Route description

History
Construction on Route 370 began in the early 1990s. It was built to replace the section of St. Charles Rock Road, then designated as Route 115, west of Interstate 270. On December 16, 1992, the first section of the highway opened allowing direct access to St. Charles at Route 94 from I-270. It replaced the crumbling Old St. Charles Bridge that carried Route 115 traffic. On April 1, 1993, the road was designated as Route 370. In 1993, the Great Flood of 1993 surrounded much of the highway which is built on top of an embankment. As the flood waters surrounded the highway, many of the new exits had been shut down because the roads it connected to were underwater. Despite the flood, construction resumed on the highway until it was completed in 1996.
