Missouri Gov. Mike Parson called it the worst bridge he saw on a statewide tour in 2019.Â
Now the Highway AD bridge between St. Clair and Union has been replaced, with the new span over Happy Sac Creek open to traffic.
The $1.4 million bridge project was completed in November, with the exception of some backfill and signs needing to be installed. Work started in January.
âThe project went well,â said Stephen OâConnor, Missouri Department of Transportation (MoDOT) area engineer for Franklin and Jefferson counties.
The old bridge was built in 1958, with 600 vehicles crossing it each day, according to MoDOT. It had been repaired several times over the years, including rebuilding its support columns and repairing most of the bridge deck, but it still was built on a curve with limited sight distance.
