PLANNED AS PART OF THE OUTER BELTWAY: In 1950, officials in Maryland devised plans for a "Cross-County Loop," a controlled-access highway that was to link US 240 (now I-270) in Montgomery County with the Baltimore-Washington Parkway (MD 295) in Prince George's County. It was the direct predecessor to today's Intercounty Connector and a springboard for a more ambitious highway proposal.

As plans were being accelerated for the original Capital Beltway (I-495 and I-95), the National Capital Park and Planning Commission announced in 1953 a preliminary 120-mile second beltway that was to loop through the outer suburbs of Maryland and Virginia. The Outer Beltway--as it was called then--was to enter Maryland from a new Potomac River crossing at Great Falls and continue east through the Montgomery County communities of Potomac, Rockville, and Silver Spring; then loop southeast into Prince George's County through Beltsville, Laurel, and Bowie; and back southwest through Upper Marlboro, Clinton, and Fort Washington before crossing the Potomac River again on a new bridge to Virginia.

Unlike the Capital Beltway, the Outer Beltway was not part of the Interstate highway system and thus was ineligible for 90 percent Federal financing. This meant Maryland and Virginia had to pay half the cost of the Outer Beltway. Plans for the Outer Beltway were stalled as Maryland and Virginia officials sought to accelerate completion of the Capital Beltway and other higher-priority Interstate highway projects.

Once the Capital Beltway was opened to traffic in 1964, officials shifted their attention back to the Outer Beltway. Around this time, citizen groups became more active in opposing highway projects; they had prevented construction of the Northwest Freeway--what would have been an extension of I-270 into the District--along the Wisconsin Avenue corridor.

In 1965, local groups petitioned the Maryland State Roads Commission (SRC) to move the route of the beltway north about five miles such that the Potomac River crossing would be at Block House Point instead of Great Falls. Jerome Wolff, chairman of the SRC, said the state took "a dim view" of changing route plans once they are settled, but Walter Addison, the head of the SRC's planning division, acknowledged the benefits of changing this alignment since the narrowest point between the Capital and Outer beltways (in Rockville) were only two and one-half miles apart, not enough to provide ample freeway spacing.

Even with the route of the Outer Beltway in flux, the SRC spent $3 million on rights-of-way along the original alignment throughout the 1960's, and even spent $500,000 to build a six-lane bridge to carry Connecticut Avenue (MD 185) over the proposed beltway in Silver Spring in 1968. An assistant engineer for the SRC said "some road" would go under Connecticut Avenue even if it were not the Outer Beltway.

Community groups finally succeeded in 1970 with the SRC's decision to shift the Outer Beltway to a more northerly alignment between Gaithersburg and Silver Spring; the beltway would continue on its original alignment east of Silver Spring. With the Outer Beltway planned to handle through traffic, the SRC planned a second east-west freeway--the 10-mile-long "Rockville Facility" (originally called the "Rockville Freeway")--for local traffic that was to connect Falls Road (MD 189) just west of I-270 with the Outer Beltway near New Hampshire Avenue (MD 650).

In the early 1970's, environmentalists blocked successfully any provision for a Potomac River crossing for the Outer Beltway north of the American Legion Bridge (I-495). With the northerly Potomac crossing blocked, it did not take long for Virginia officials to downscale plans for their sections of the Outer Beltway, though it was built in sections in the 1980's and 1990's as the Fairfax County Parkway (VA 7100), a partially controlled access arterial highway. Meanwhile, studies in Maryland found traffic was insufficient to build a Potomac crossing between southern Prince George's County and southern Fairfax County in Virginia. Although the Outer Beltway lingered in long-range county and regional plans, it was removed as a line item in budgets beginning in 1974 due to a deep recession, lower gas tax revenues generated from the 1973-1974 oil shock, and increased environmental concerns. By 1977, the Outer Beltway was all but dead; Maryland officials killed the beltway officially in 1980.

This map shows the project limits of the Intercounty Connector:

  • Contract A (in green): I-370 east to MD 97; completed in February 2011

  • Contract B (in purple): MD 97 east to US 29; scheduled completion early 2012

  • Contract C (in yellow): US 29 east to I-95, including new C/D lanes on I-95 south of the proposed EXIT 31 (MD 200 / ICC); scheduled completion early 2012

  • Contact D (in light blue): new C/D lanes on I-95 north of the proposed EXIT 31 (MD 200 / ICC); scheduled completion to be determined

  • Contract E (in red): I-95 east to US 1; scheduled completion to be determined

FROM THE ASHES OF THE OUTER BELTWAY: One section of the Outer Beltway--the section from I-270 in Gaithersburg east to the Baltimore-Washington Parkway (MD 295) in Beltsville--survived the planners' axes and in 1975, the Metropolitan Washington Council of Governments supported the Maryland State Highway Administration's (SHA) planning and engineering study for the route. The route, which was first called the "Intercounty Connector" (ICC) in 1977, was to provide a direct east-west link between I-270, I-95, and BWI Airport while removing traffic on congested local roads. Plans for the Intercounty Connector, whose cost originally was estimated at $221 million, actually had preceded those for the Outer Beltway by three years.

Almost immediately, the truncated route stoked controversy. Environmentalists feared the then-planned eastern terminus of the Intercounty Connector at the Baltimore-Washington Parkway would encroach on the Patuxtent Research Refuge, a large plot operated by the US Fish and Wildlife Service. In acknowledgement of these concerns, the National Capital Planning Commission (NCPC) recommended to the SHA in 1983 that the connector be shortened from MD 295 four miles west to I-95 to avoid damage to the reserve.

Other critics such as then-Montgomery County Executive Charles Gilchrist said construction of the Intercounty Connector was "infeasible" at least prior to 2000. Gilchrist suggested widening local roads such as MD 28, MD 182, MD 650, and MD 198 between Rockville and Burtonsville to minimize community and environmental impact. The $83 million price tag for this alternative was about one-third the cost of the proposed ICC. The most ardent environmentalists opposed any road construction and favored transit use in this corridor, while pro-ICC forces--including one official at the NCPC--derided Gilchrist's alternative as "penny-wise and pound-foolish."

Through much of the 1980's, the Intercounty Connector was considered a project to be built in conjunction with the Rockville Facility; the local press often referred to the combined project as "ICC / RF."  Hopes for building the Rockville Facility were dashed in 1989 when the SHA turned over 102 acres of right-of-way over to the state's Department of Natural Resources, which designated the land as Matthew Henson State Park.

I-370 AND THE ICC: One early success along the Outer Beltway / ICC route was the development of I-370, which was conceived as a 2.5-mile-long connecting route between I-270 and the then-proposed Metro-Red Line extension to Shady Grove. The Shady Grove extension was approved in 1975, and two years later, I-370 was approved with Interstate highway transfer funds--mostly from unbuilt Baltimore highways--as a controlled-access link between the station and I-270 to be built in the Outer Beltway right-of-way. Work on the I-370 connector did not begin until 1984; the SHA opened the $169 million connector to traffic on December 22, 1988.

THE ICC VERSUS GLENDENING AND "SMART GROWTH": Throughout the 1990's, proponents of the ICC appeared to lose momentum as the tenets of "smart growth" grounded in densely populated communities connected by mass transit came into vogue. In 1992, the U.S. Environmental Protection Agency (EPA) began studies on the proposed route that culminated in a draft environmental impact statement five years later.

The 1997 draft statement stated the "master plan alignment" of the highway would destroy at least 145 acres of parkland, remove 22 acres of wetlands, cut across 77 streams and affect 27 species of birds. A northerly alignment would have had a reduced environmental impact, but would require the condemnation of 84 homes. Given these two potentially unpalatable choices, Governor Parris Glendening requested the state abandon plans for the ICC, reversing a campaign pledge he made to build the highway in his gubernatorial campaign. (Interestingly, Glendening supported the ICC as Prince Georges County Executive in the early 1990's, often locking horns with Montgomery County Executive Neal Potter, who opposed the project.)

However, stopping the ICC ultimately proved difficult. As the state already owned much of the land, pro-ICC proponents would have been able to stop such a sale at the Maryland Board of Public Works (BPW), which must approve excess right-of-way transactions back into public hands. The Montgomery County Planning Board said removing the ICC from their master plan would take six or seven years.

The ICC favored heavily in the 1998 election, and as "smart growth" initiatives gained traction that year across the country, Glendening--the Democratic candidate coasted to victory over GOP challenger Ellen Sauerbrey. Nevertheless, Glendening convened a panel called the Transportation Solutions Group (TSG) to study the proposed route, and in February 1999 the panel voted eight to four in favor of building a four-lane toll road (with two lanes in each direction) along the route of the ICC.

Transportation consultant and TSG member Kenneth Orski told the
Toll Roads News web site the following about the approved ICC plan:

The favored plan represents a compromise between those who oppose any new road and a full-fledged freeway sized to cater fully to projected (unpriced) demand. It will be a pioneering project because the panel is fully persuaded that only by using pricing in a creative way will it be possible to finance the road and also to contain demand to the dimensions of a road that we believe will have minimal environmental impact.

The TSG's rendition of the ICC called for a four-lane tollway with variable pricing and free or discounted use for carpools (i.e., high occupancy toll or HOT lanes). Pricing would range from 13 cents per mile in off-peak periods to 17 cents per mile in off-peak periods; it was assumed most ICC travelers would travel short distances and not the entire length. The width of the proposed TSG alternative was to be only 80 feet and the right-of-way only 164 feet, approximately half the right-of-way required by the state's official proposal. Nevertheless, Glendening rejected the TSG's findings on the grounds that it was incompatible with "smart growth" initiatives.

EHRLICH MOVES THE ICC TO THE FAST TRACK: By 2002, however, the focus had shifted to stimulating growth, creating jobs, and relieving congestion, and Republican gubernatorial candidate Robert Ehrlich, who campaigned on an anti-congestion platform, won the election that year. The 2002 election also ushered in a slate of new members on the Montgomery County Council who like Ehrlich favored construction of the ICC. As the official consensus began to sway in favor of the ICC, the National Capital Regional Transportation Planning Board (TPB) voted in 2004 to include the highway in its regional transportation plan, determining the ICC met air quality goals and that funding could be obtained through tolls.

On July 11, 2005, Governor Ehrlich announced plans to build the ICC along Corridor 1, most of which ran along right-of-way purchased already by the state for the long-dormant Outer Beltway. This plan would require the condemnation of 57 homes on land not purchased already for the route. The northerly alternative, now called Corridor 2, would have had a reduced environmental impact, but would have required the condemnation of 83 homes and more significant outlays for land purchases. It also would have encroached on the Rocky Gorge Reservoir--which is an important water supply for the Washington area--and doing so effectively would have jettisoned the project altogether.

Ehrlich appealed to President George W. Bush to move the ICC to the fast rack; its approval as a high-priority project meant would Federal resources would be directed and the approval process would be streamlined for the ICC. The BPW approved the selection of Corridor 1 on August 31, 2005, and the Federal Highway Administration (FHWA) followed suit on May 30, 2006, stating that Maryland had satisfied "all environmental, economic, and community requirements" in order to build the ICC.

Engineers and landscape architects applied their expertise to blend the Intercounty Connector (MD 200) into the surrounding landscape. These simulated photos show (top) a typical overpass on the ICC and (bottom) the ICC crossing Rock Creek. (Photos by Maryland State Highway Administration.)

THE ICC TAKES SHAPE: Ehrlich broke ground for the ICC on October 25, 2006, but even as he lost the governorship to Democratic party challenger Martin O'Malley less than two weeks later, O'Malley pledged to continue work on the ICC. Work on the first of the construction contracts began on November 13, 2007.

Work on the ICC, which is being undertaken jointly between the SHA and the Maryland Transportation Authority (MdTA)--the toll agency that will take over the highway upon completion--is divided into the five separate contracts. Work on the initial 7.2 miles under Contract A has been completed, while two additional contracts remain under construction.

CONTRACT A: Begun on November 13, 2007 and opened to traffic on February 23, 2011, Contract A extended from the western limit of the ICC project at the I-370 / MD 355 (Frederick Road) interchange east to the MD 97 (Georgia Avenue) interchange. The cost of this 7.2-mile-long section was $479 million. This section is expected to carry approximately 100,000 vehicles per day (AADT).

  • MD 355 (Frederick Road) in Gaithersburg: rebuilt as modified directional-T interchange with single roadway leading to MD 355; eliminated eastbound slip ramp to Shady Grove Road

  • Spur to Metro-Shady Grove in Gaithersburg: built as directional-T interchange; there is an existing curve from I-370 into the Shady Grove spur

  • MD 97 (Georgia Avenue) in Rockville: built as modified cloverleaf, reserved land at southwest corner of interchange for future park-and-ride lot

The Intercounty Connector continues the exit numbering scheme of the adjacent I-370 eastward, though mileposts are marked for MD 200. The passenger car toll using EZ-Pass is $0.25 per mile in peak periods (Monday through Friday 6:00-9:00 AM and 4:00-7:00 PM), $0.20 per mile in off-peak periods, and $0.10 per mile in overnight periods (11:00 PM-5:00 AM every day), with a $3 surcharge for non-EZ-Pass users.

Note the wide right shoulder through the tunnel, which may be used in the future for an additional lane in the eastbound direction. (Photo by C. Patrick Zillacus.)

This 2010 photo shows the southbound I-95 at the future EXIT 31 (MD 200 / Intercounty Connector) in Laurel. This section of MD 200, along with new collector-distributor (C/D) roads along I-95 between EXIT 29 (MD 212) and the new EXIT 31, are scheduled for completion in early 2012. However, an extension of the I-95 C/D roads north to EXIT 33 (MD 198) has been postponed indefinitely. (Photo by Steve Anderson.)

TWO SECTIONS STILL UNDERWAY, TWO OTHERS POSTPONED: Work continues on 10.7 miles of MD 200 from MD 97 east to I-95. The entire length of this section, which is being undertaken in two separate contracts, is slated to open in early 2012. However, the extension of MD 200 from I-95 east to US 1, as well as the C/D roads on I-95 north of MD 200, have been postponed indefinitely.

CONTRACT B: Begun on January 16, 2009 and scheduled for completion in early 2012, Contract B extends from the MD 97 interchange east to the US 29 (Columbia Pike) interchange. The projected cost of this 7.0-mile-long section is $560 million. Upon completion, this section is expected to carry approximately 65,000 vehicles per day.

  • MD 182 (Layhill Road) in Silver Spring: build as diamond interchange

  • MD 650 (New Hampshire Avenue) in Silver Spring: build as single-point urban interchange ("SPUI")

  • US 29 (Columbia Pike) in Silver Spring: build as modified three-level "stack" interchange, with one cloverleaf loop for the MD 200 eastbound to US 29 northbound movement (all other movements on conventional and flyover ramps

CONTRACT C: Begun on April 7, 2008 and scheduled for completion in early 2012, Contract C extends from the US 29 interchange east to the I-95 interchange in Laurel. The projected cost of this 3.7-mile-long section and the 1.9 miles of C/D roads on I-95 is $514 million. Upon completion, this section is expected to carry approximately 85,000 vehicles per day.

  • Briggs Chaney Road in Silver Spring: build two slip ramps to eastbound MD 200 and from westbound MD 200 (no direct access from eastbound MD 200 or to westbound MD 200; these movements would be completed via nearby US 29)

  • I-95 in Laurel: build modified cloverleaf interchange, but with flyover ramps from eastbound MD 200 to the I-95 northbound C/D road and from the southbound I-95 C/D road to eastbound MD 200; this part of the project includes the extension of the I-95 C/D roads from the new EXIT 31 (MD 200 / Intercounty Connector) south to EXIT 29 (MD 212) in Beltsville

CONTRACT D: This contract entails the extension of three miles of C/D roads on I-95 north from EXIT 31 to EXIT 33 (MD 198 / Sandy Spring Road) in Laurel, resurfacing of 4.9 miles of I-95 north from EXIT 29 to EXIT 33, and construction of a new EXIT 32 "parclo" interchange with Contee Road (realigned Van Dusen Road) that would serve Konterra Town Center. The $85 million Contact D was slated for completion in late 2011, but given the recession and weak commercial real estate markets, which have delayed construction of Konterra Town Center (despite its approval by Prince Georges County officials in February 2009), as well as the postponement of a bond issuance amid turmoil in the credit markets, the SHA and MdTA deferred contract D under further notice.

CONTRACT E: Scheduled to begin construction in the fall of 2009 and be completed in late 2011, Contract E extends from the I-95 interchange east to the terminus at US 1. The $65 million project originally was scheduled to begin construction in the fall of 2009 and slated for completion in late 2011, but like Contract D, this contract also was postponed pending future development at Konterra Town Center. The projected cost of this 0.9-mile-long section is $65 million. Unlike the westerly sections of MD 200, which are to be built with six lanes (three in each direction), this final section of the ICC is to be built with only four lanes; upon completion, this section is expected to carry only about 40,000 vehicles per day.

  • Virginia Manor Road in Laurel: build two slip ramps to westbound MD 200 and from eastbound MD 200 (no direct access from westbound MD 200 or to eastbound MD 200)

  • US 1 (Baltimore Avenue) in Laurel): build grade-level signaled intersection with US 1; reserve land at northwest corner of intersection for an MdTA maintenance facility

This diagram shows a typical cross-section of the Intercounty Connector (MD 200). Built within a 250-foot to 300-foot right-of-way, the ICC is to be built with two three-lane carriageways separated by a 36-foot-wide grassy median. However, the shoulders are to be only 10 feet wide, not the 12-foot-wide Interstate standard adopted in recent years. (Diagram by Maryland State Highway Administration.)

EXTEND THE ICC EAST TO (AT LEAST) THE BW PARKWAY: The Intercounty Connector should be extended east of US 1 to the Baltimore-Washington Parkway (MD 295) in the vicinity of MD 197 (Laurel-Bowie Road). The ICC extension would provide a more direct link to Fort Meade and BWI Airport to the north and the NASA-Goodard Space Center to the south. Upon completion, the ICC should receive the I-470 designation, denoting its status as a key link between I-270, I-95, and MD 295.

Some suggest extending the ICC further southeast to John Hanson Highway (I-595 / US 50) to provide additional relief to the Capital Beltway (I-95 / I-495). However, heavy development near Bowie likely will preclude this extension.
