Route 27 is an arterial road, with a 45 mph speed limit and three lanes in each direction. The bridge links Northern Virginia to the North Parking of the Pentagon, Arlington Cemetery, and downtown Washington, D.C. The original six-lane overpass bridge on Route 27 was built in 1946 within view of the newly constructed Pentagon. The passage of nearly 70 years and 10 million cars and trucks has necessitated the replacement of the bridge’s superstructure.
OHLA USA company, Judlau Contracting, Inc., commenced work on this highly visible project in April 2015. The new bridge superstructure will be a 460’ long, six-span, slightly curved structure that is 9’ wider with three 12.5” lanes in each direction, a protected 8’ sidewalk on the west side, and a protected 14’ shared use path on the east side. The granite stone facing currently on the abutments will be removed, cleaned, and reinstalled. New abutments and new piers will be supported on drilled shafts with permanent steel casings. The structure will be demolished and rebuilt in four phases, to allow for four lanes of traffic to flow at all times.
