Wentzville Parkway South Phase 1

Phase 1:
The interchange improvements to Wentzville Parkway at I-70 will remove the existing eastbound on-ramp and fold it to move the ramp terminal to the outer road. Traffic southbound on Wentzville Parkway attempting to head east on Interstate 70 will make a right turn at the south outer road (Veterans Memorial Parkway), and then a U-Turn at a proposed roundabout to access the interstate. This configuration allows the predominate movement at the interchange, southbound to eastbound, to be performed through a series of right turns, rather than a left turn at a signalized intersection. The relocations of the eastbound on-ramp also allow for a longer acceleration lane for this movement in advance of a curve along the interstate.
