ST. CHARLES COUNTY – Drivers traveling westbound on Route 370 wishing to access eastbound Interstate 70 need to consider alternate routes as bridge repair work will close the Route 370 flyover exit ramp to eastbound I-70 for one month starting Wednesday, April 13, weather permitting.

St. Charles County plans to realign the intersection of Route N and Route Z to a new four-way signalized intersection east of the current offset/”bowtie” intersection. Due to considerable existing traffic delays at the intersection, MoDOT was able to get federal funds through the East-West Gateway Council to reconstruct the intersection.

A project decades in the making reached another milestone on November 17, 2021, when the new David Hoekel Parkway (DHP) interchange officially opened to traffic at Interstate 70 in Wentzville. A ribbon-cutting ceremony was held on November 17 to commemorate its completion.

The East-West Gateway Council of Governments (EWGCOG) Board of Directors voted on Wednesday, October 27, 2021, to approve $39 million in its Transportation Improvement Program (TIP) to fix the #1 bottleneck in the St. Louis region: the Wentzville “Curve” on I-70 near the interchange of I-64/I-70/US 61.

Work to reconfigure and improve the intersection at Hwys. N and Z has been delayed.
