Award of Merit - Transportation

The existing Adelaide Bridge over North Third and Broadway in St. Louis was built in 1972. Located directly above two rail systems, it is the only thoroughfare for the area’s trucking industry to get to and from the industrial businesses on Hall Street.

Many who travel the bridge regularly voiced concern for their safety as the 30-plus-year-old bridge deck showed obvious signs of deterioration.

In order for traffic to continue on the bridge, MoDOT needed to make the necessary maintenance improvements, including demolition and reconstruction of the superstructure, widening of the roadway, new drainage system, upgraded lighting on and below the bridge and upgraded ADA accommodations.

The new bridge is welcome news for St. Louis motorists and the trucking industry, as it has improved the safety and capacity of Adelaide Street.

Total length of the improvement was 1,505 ft.
