About the Project
This project will modify and repair the Route 27 (Washington Boulevard) bridge over Route 110 (Jefferson Davis Highway) in Arlington County. The existing bridge, located adjacent to the Pentagon, carries three lanes of traffic in each direction, has a concrete sidewalk on each side and a 6-foot-wide concrete raised median. The bridge was built in 1941 and is considered structurally deficient. In 2002, Route 110 was realigned just south of the bridge.
The bridge will be widened by 9 feet to 105 feet, to accommodate a 14-foot shared-use path on the east side, and an 8-foot sidewalk on the west. The superstructure will be replaced and widened, expanding the length of the bridge to 470 feet by adding two new end spans. The existing slab vault structure behind the abutments will be completely replaced by two new piers and abutments, adding an additional span at each end of the bridge.
The new bridge superstructure will be shallower than the existing bridge superstructure, increasing the westbound Route 110 vertical clearance from 15 feet 4 inches to 17 feet.
The new bridge's aesthetics include decorative wrought-iron picket fencing, low-level LED pedestrian lighting, gateway pillars, a recessed concrete pattern on parapets and forest-green color. The crowning touch will be signature medallions on the bridge’s gateway pillars honoring each of the four branches of the U.S. Military: Army, Navy, Marine Corps, and Air Force.

Estimated project costs:
Preliminary engineering: $2.5 million
Right of way: $30,000
Construction: $29 million
Total: $31.5 million
Estimated completion: May 2018
Traffic on Washington Boulevard will be reduced from three lanes to two northbound and southbound for the duration of the project. VDOT will maintain a minimum of two lanes in each direction on both Routes 27 and 110, other than temporary night closures to install bridge girders. Pedestrian traffic will be shifted to a temporary bridge in 2016.
As of 2013, Rt. 27 carries 71,500 vehicles per day and Rt. 110 carries 61,500 vehicles per day.
