Route 94 and Route D Improvements include the following:
- Providing a second westbound Route 94 through lane at the Route D intersection and extending that approximately 0.25 miles to the east Francis Howell High School entrance.
- On Route D, add a second left turn lane from southbound Route D to eastbound Route 94.
- Converting the rear Francis Howell High School entrance into a three-quarter access driveway (left-in; right-in/right-out) while widening Route D to add left-turn lanes at the same intersection.
- Installing new signals and lighting at the intersection of Route 94 and Route D.
Route 94 Widening includes the following:
- Widening Route 94 from two lanes to four lanes for approximately 1.0 miles from Route D to the I-64 interchange.
To make these improvements, provide drainage and safe slopes, and maintain a utility corridor, additional right of way will be required, including a 0.80-acre section from the August A. Busch Conservation Area (Conservation Commission of Missouri) and a 0.13-acre section of Weldon Spring Conservation Area. MoDOT will begin outreach to affected property owners soon.
Access will be maintained during construction, and no direct impacts are expected to the nearby Hamburg Trail and Busch Greenway. Travel delays and short-term detours may be encountered during construction.
