Highlights
We coordinated with the City of Austin & The Parks and Recreation Dept. to shut down the 800-1100 blocks (4 lanes) of W. Cesar Chavez Street in order to build the entire 225,000 lb. substructure of the pedestrian bridge in one weekend. We shut the road down at 8pm on September 17th, and by 10 pm on September 19th, we had erected 4 structural steel girders (including 2 air splices), 26 floor beams, 13 lateral braces and wood decked the entire length of the walkway.
Another interesting aspect of the bridge is the Brazilian hardwood railing, called Ipe Ironwood. The railing lines both sides of the pedestrian walkway, including 32 directional lights for nighttime use, and adds a touch of Austin to make this bridge a prominent part of the town lake experience.
Due to the variance in elevation between the bridge and the future park below, the design had us import 5,000 CY’s of embankment encased in 1,500 SF of mortared stone veneer revetment and 420 LF of a mortared block stone seatwall.
Integral colored concrete spans the entire length of the bridge from the tie in on the South side of Cesar Chavez to the North side roundabout of the Lamar Corridor.
