About the Project
This project is modifying and repairing the Route 27 (Washington Boulevard) bridge over Route 110 (Jefferson Davis Highway) in Arlington County. The original bridge, located adjacent to the Pentagon, carried three lanes of traffic in each direction and had a concrete sidewalk on each side and a six-foot-wide concrete raised median. The bridge, built in 1941, was in poor condition prior to reconstruction. In 2002, Route 110 was realigned just south of the bridge.
The bridge is being widened by nine feet to 105 feet, to accommodate a 14-foot shared-use path on the east side (10 feet wide on the bridge approaches), and an eight-foot sidewalk on the west. The superstructure is being replaced and widened, expanding the length of the bridge to 470 feet by adding two new end spans. The slab vault structure behind the abutments is being 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 original 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
On Dec. 26, 2017, the permanent shared-use path for bicyclists and pedestrians along eastbound Route 27 opened. On the night of Dec. 27, 2017, eastbound Route 27 traffic shifted to the right onto the newly constructed portion of the bridge; this allows crews to demolish the middle portion of the original bridge and rebuild it.
Traffic on Washington Boulevard has been reduced from three lanes to two in each direction and will remain as such for the duration of the project. VDOT is maintaining a minimum of two lanes in each direction on both Routes 27 and 110.
As of 2013, Route 27 carries 71,500 vehicles per day and Route 110 carries 61,500 vehicles per day.
