The work will include building the final one-mile segment on the ICC’s eastern end between Interstate 95 and U.S. Route 1 in Prince George’s County, officials said. New lanes also will be built parallel to I-95 to help traffic merge between exits for the ICC and MD Route 198, officials said.

The contract was awarded to a joint venture of Shirley Contracting Co., Clark Construction Group, Facchina Construction Co. and Trumball Corp. The same joint venture built the 3.7-mile section of the ICC between U.S. Route 29 and I-95.

The 18.8-mile toll highway opened fully between Shady Grove and Laurel in November and connects the I-270 and I-95 corridors outside the Capital Beltway. The entire project will be completed within its $2.5 billion budget, highway officials said.
