The Old Chain of Rocks Bridge formerly carried historic Route 66 over the Mississippi River. Currently the bridge carries bicycle and pedestrian traffic, and is a popular location for ‘eagle watching’ during the winter months. This bridge has a unique feature with a 22-degree bend near the middle. This project consisted of various steel and concrete repairs, as well as painting of the structure entrances. Most of the repairs required special equipment to gain access to the work. In some of the spans an interesting problem had developed; without the load of vehicular traffic the concrete deck had raised off of the structural steel below. Part of our contract was to shim and attach the concrete deck to the roadway beams below. With the age of the structure various connection plates were deteriorated to the point of needing replacement. Finally the entrances were painted to add an aesthetic appeal.
