STV provided construction management and program management services on behalf of the Maryland Transportation Authority (MDTA) for comprehensive improvements along eight miles of Interstate 95 in Baltimore County. The project included 12 new bridge structures, 2 bridge replacements, 5 new noise barrier systems, and construction of the state’s first 2-lane express toll lanes to reduce traffic congestion.

This segment of Interstate-95, otherwise known as the “Spaghetti Bowl Interchange,” was the most congested portion of the highway north of Baltimore due to the complex geometry of its ramps. STV developed a manual to guide all construction management activities and processes with designated management staff for each of the construction contracts.
