Location

The bridge was built in 1960 and rehabilitated in 1994. Its main span was 550.7 feet (167.9 m) and had a total length of 3,017.2 feet (919.6 m). Its deck width was 60.3 feet (18.4 m), allowing for four lanes of traffic (two in each direction) and minimal shoulders. Vertical clearance was 20 feet (6.1 m).

In 2019, the Missouri Department of Transportation received a $81.2 million federal INFRA grant which provided the remaining necessary funding to replace the aging bridge.[1][2] On July 1, 2021, MoDOT selected the Lunda Team as the design-build contractor for the project. The design includes two bridges (one for each direction of travel); each bridge will accommodate three travel lanes and full-width shoulders. Construction on the first bridge began in October 2021.[3] The first was done in summer 2023 carrying both westbound and eastbound, will eventually be only carrying westbound only. The original bridge was imploded on the morning of September 10th of the same year. Fog delayed the implosion by over an hour.[4] The second bridge for eastbound will be constructed afterwards. The entire project is scheduled to be completed by the end of 2024.[5]
