, "Many truss members were replaced with new fabricated galvanized steel. Floor system members and the open steel grid deck were replaced in the first three bays of each end span. All remaining structural steel was blast cleaned, metallized, and painted. A new wooden sidewalk was installed and renovations were made at both approaches to the bridge."

Structure

Washington Crossing Bridge is a six-span double Warren truss structure measuring 877 feet (267.3 m) in length. Its riveted-steel grid deck provides a roadway width of 15 feet (4.6 m). The roadway is made of a grate.The bridge's substructures, composed of rubble stone-faced masonry, are from the original 1831 bridge, while its superstructure dates to 1904. Five piers (one of which has been faced with mortar) and two abutments support the bridge. The downriver (south) side of Washington Crossing Bridge supports a cantilever

 were the cause of the rainfall, which totaled 3 to 5 inches (127 mm) in a 12-hour period. Flood peaks along the main section of the Delaware River were the highest since the flood of 1955. The bridge was temporarily closed.
Unusually heavy rains experienced in late March 2005 and early April 2005 combined with melting snow resulted in another flood. One of the piers of Washington Crossing Bridge had its masonry core exposed after being battered by a floating object. In the aftermath of the flood, the Delaware River Joint Toll Bridge Commission requested $500,000 in emergency flood repairs. Although the bridge remained opened for a short time following the flooding, it was closed on April 7, 2005, when receding flood waters revealed the extent of the damage to the pier. The bridge was reopened to continuous traffic on May 4, 2005, although it was closed for nighttime repairs beginning May 18.

Most recently, in 2006, the Delaware River experienced 3 to 6.5 inches (165.1 mm) of rain from June 23 to June 28. The river's peak levels were comparable to those of the April 2005 flood. Washington Crossing Bridge was closed until July 1, when it reopened to vehicular and pedestrian traffic at 10:15 a.m.
