Process to Fully Open Both Roadways Starts Friday Evening; Motorists Are Urged to Pay Attention to New Traffic Patterns

(November 5, 2014)  – Beginning Friday evening, November 7, crews will begin opening the final section of the Intercounty Connector (ICC) / MD 200 to US 1 in Prince George’s County.  During this same time, crews also will begin opening the I-95 / Konterra Drive (formerly Contee Road) Interchange, located between the ICC and MD 198.  Both the ICC and the new interchange will open to traffic by morning rush hour on Monday, November 10, weather permitting.

The last segment of the ICC extends 1.5 miles from I-95 to US 1 in Laurel.  This project also includes a partial interchange at Konterra Drive and a signalized intersection at US 1 (click here for fact sheet) near the MARC commuter station on Muirkirk Road.  Commuters will have improved access to the Muirkirk MARC Station by traveling eastbound on the ICC/MD 200 to Konterra Drive (Exit 20), turn right, then left at the traffic signal on Muirkirk Road over US 1 to a left into the entrance for the MARC station.  The final ICC contract included improvements to I-95 to create new collector-distributor (CD) lanes for access to and from the new Konterra Drive, the ICC and MD 198 interchanges (click here for project map).  The consolidated exits improve safety by separating slower exiting and entering traffic from mainline travel lanes.

The portion of the ICC between I-270/I-370 and MD 97 opened February 2011 and the remainder to I-95 opened to traffic November 2011.  The State Highway Administration (SHA) designed and built the toll highway, which is operated and maintained by the Maryland Transportation Authority (MDTA).  The ICC is an all-electronic, variably priced toll facility, where higher tolls are charged during peak-travel times (Monday through Friday, between 6 - 9 am and 4 - 7 pm) and reduced tolls are charged during off-peak and overnight hours.  ICC tolls are collected at highway speeds using E-ZPass® and Video Tolling to maintain relatively free-flowing traffic conditions.  The ICC per-mile toll rates will remain the same with the opening to US 1.

Simultaneous to the opening of the final segment of the ICC, SHA will open a new I-95 interchange at Konterra Drive.  Located along I-95 between the ICC and MD 198, the new interchange will serve Konterra Drive, which extends from Old Gunpowder Road to the west to Muirkirk Road to the east, providing better access to the Laurel Regional Hospital and a future 2,200-acre mixed-use development at Konterra.

Motorists should use caution when traveling through the area over the weekend as crews will open the connecting ramps, roads and CD lanes in phases.  Drivers are urged to follow signs, watch for construction crews and prepare for new traffic patterns.

SHA’s contractor for the final ICC project was a joint venture design-build team including Shirley Contracting Company, LLC, Clark Construction Group, LLC, Facchina Construction Company, Inc. and Trumbull Corporation.  The lead design firm was Dewberry & Davis, LLC.   The contractor for the I-95/ Konterra Drive interchange was American Infrastructure, Inc.

Motorists Should Anticipate Heavy Traffic & Delays on Nov. 9


WHAT:  Weather permitting, the eastbound span of the Bay Bridge (US 50/301) will be closed temporarily to traffic.

Two-way traffic operations will be in place on the westbound span. One lane of traffic will operate in each direction on the westbound span, with the center lane closed to traffic.  NOTE:  The center lane may open to traffic intermittently to help reduce westbound delays.

In addition, two detours will be in place on the Eastern Shore due to the race:

  • The off-ramp from US 50 eastbound to MD 8 will be closed during the event. A detour will be in place to direct motorists to the next exit at Thompson Creek Road. From there, motorists will travel westbound on MD 835 to the signal at MD 8.
  •  The on-ramp from southbound MD 8 to westbound US 50 also will be closed during the event. All traffic attempting to access westbound US 50 will be directed to MD 18, to the roundabout at Castle Marina Road and onto US 50 west.

WHEN:  Sunday, Nov. 9, from approximately 2 a.m. - 2 p.m.                         

WHY:  The "Across the Bay 10K" running event will be held on the eastbound span.  For additional information on the event, visit

Motorists using the Bay Bridge on Nov. 9 will experience significant delays throughout the day and early evening.  To avoid delays, motorists are urged to travel prior to 6 a.m. or after 6 p.m.
