Scope of Work
Cianbro replaced the deck on the 6,000 lf Woodrow Wilson Bridge.

Project Details
  • Diverted two-way traffic to one side of the bridge
  • Performed night work from 8:30 p.m. to 5:30 a.m.
  • Employed a 7 ft rotary saw to cross-cut the deck into 46 ft by 12 ft sections
  • Removed deteriorated deck panels with a crane and lowered them to a barge below
  • Sandblasted and coated the exposed steel work
  • Installed 1,026, 46 ft by 12 ft precast, post-tensioned (longitudinally and traversely) concrete deck panels
“We should take notice here in Congress that someone, somewhere in the great bureaucracy had found a corporation that allows the construction of a bridge to be completed not only on schedule but ahead of schedule.  I commend whoever it is who owns that corporation.” 
Congressman Dan Mica - Congressional Record
  

Project Awards

Completing this project seven months ahead of schedule, Cianbro received the following recognition:
  • Engineering News Record (January 5, 1984) “Those Who Made Marks in 1983”
  • AGC’s Build America Award
  • AAA’s Commendation Award on the behalf of 135,000 daily users of the bridge

Unique Challenge



The Cianbro team successfully designed and fabricated steel grid, precast, concrete deck panels, which quadrupled the rate of deck replacement and allowed for the 6-lane, peak rush hour traffic during the day. Scaffolding was also used to prevent debris from contaminating the river and national parkland beneath the bridge. This allowed the area to remain open to the public throughout construction.
