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 I-270.[citation needed]
MoDOT applied for an interstate highway designation of Interstate 370, but AASHTO rejected this in favor of the designation of Interstate 870. MoDOT did not want this because I-870 was their intended designation for what is now Interstate 255.[3]
On December 16, 1992, the first section of the highway opened allowing direct access to
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.[citation needed
