Mulligan Road Project

Mulligan Road Project

Project Description

This project consists of the construction of a new connector road (Mulligan Road) between Richmond Highway (U.S. Route 1) and Telegraph Road (VA Route 611) in the vicinity of Fort Belvoir in Fairfax County, Virginia. The project is located in Fairfax County, approximately 6 miles south of the Capital Beltway (I-495), 3 miles east of I-95, and 6 miles west of George Washington's Mount Vernon estate and the Potomac River. The U.S. Department of Defense (DoD) eliminated public access to Beulah Street (VA Route 613) and Woodlawn Road (VA Route 618) within Fort Belvoir following the events of September 11, 2001. These roads linked U.S. Route 1, a north-south principal arterial, and Telegraph Road (VA Route 611), a north-south minor arterial. The two roads are otherwise connected about two miles to the south by the east-west cross-county Fairfax County Parkway (VA 7100), and about 7 miles north via South Kings Highway.

Fort Belvoir is a garrison of the U.S. Army, comprising approximately 7,682 acres with multiple missions to support the military. The Humphrey's Engineer Center (HEC) is a 583 Acre U.S. Army Corps of Engineers (USACE) facility located contiguous to the northeast portion of Fort Belvoir. The Federal Highway Administration (FHWA) is the lead federal agency for the proposed replacement project. FHWA proposes to provide a replacement facility to the closed Woodlawn Road, in conjunction with U.S. Department of the Army Defense Access Road (DAR) Program, U.S. Army Fort Belvoir Garrison, HEC, USACE Baltimore District, Virginia Department of Transportation (VDOT), and the Fairfax County Department of Transportation (FCDOT).

This ultimate project will include the construction of a four-lane divided roadway with a median on a new alignment, construction of new bridges and large culverts at stream crossings/wildlife passages, asphalt pavement removal and reconstruction through a portion of the project limits, construction of a new shared use path along Mulligan Road, utility relocations, right-of-way acquisition/federal lands transfers, traffic signal installation, and other miscellaneous work. The proposed project would be funded in part through the DAR Program, as well as other federal, state and local sources.
