History

Construction on SR-370 began in the early 1990s. It was built to replace the section of St. Charles Rock Rd, 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 SR-115 traffic. On April 1, 1993 the road was designated as SR-370. Later in 1993 a great flood 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.
