PARK ROAD OVER/UNDER TUNNELS: PROBLEMS AND SOLUTIONS

The Park Road Tunnels is a 3220-foot (1056 m) connector between two stations in an over/under configuration down a narrow public right-of-way. An over/under configuration was chosen to avoid the necessity of taking a church and 15 residences. Other design problems included known hydrocarbon contamination and squeezing a double deck fan shaft and emergency exit into a small footprint. This project is one of five that comprise the Mid-City E Route segment of the Washington Metropolitan Area Transit Authority's (WMATA) effort to fast track construction of the remaining 13.5 miles (8.4 km) of the system.
