Little Hills Expressway & Mel Wetter Roundabout Sponsor Saint Charles Project No. RB18-000008 Project Type New Road TOTAL FUNDING Total County Sponsor Federal $2,000,000 $500,000 $500,000 $1,000,000 Project Description The Mel Wetter and MO 370 Interchange Study has identified the intersection of Mel Wetter Parkway and Little Hills Expressway to have significant traffic delays and experiencing an increase traffic volume due to new developments. A recent traffic impact study prepared for the Villages of Provence, a new residential development on Mel Wetter Parkway south of MO-370, forecasts increasing traffic volumes that will warrant intersection improvements at Mel Wetter Parkway and Little Hills Expressway. Multiple conceptual layouts were developed during the Mel Wetter and MO 370 Interchange Study with County and MoDOT participation. After a detail evaluation, Alternative A with a roundabout at Mel Wetter Parkway and Little Hills Expressway was the preferred alternative. Summary of Alternative A: Expand the MO-370 interchange at Route 94 to include access to Mel Wetter Parkway through the addition of a collector distributor (C-D) road system; redesign the intersection at Mel Wetter Parkway and Little Hills Expressway with a roundabout; new signalized intersection on Mel Wetter Parkway with the south C-D road. The City of Saint Charles is requested County funds for the design and construction of the roundabout at Mel Wetter Parkway and Little Hill Expressway. The roundabout will be constructed within existing City Right-of-Way. The roundabout will be designed and constructed to accommodate future MO 370 ramps and connection to the north collector distributor C-D road. The City of Saint Charles will be applying for Federal CMAQ Funds for the roundabout. The funding, design, and construction of the C-D roadway system, additional ramps, and interchange improvements will be further discussed with MoDOT and will be a future project. The new roundabout will improve traffic flow, safety, and reduce emissions at the intersection. The roundabout will be designed to accommodate the forecasted 2040 traffic volumes and improve the overall level of service at the intersection. According to the FHWA Office of Safety, roundabouts are a Proven Safety Countermeasure because of their ability to substantially reduce the types of crashes that result in injury or loss of life. Roundabouts are designed to improve safety for all users, including pedestrians and bicyclists, by reducing speed of traffic and reducing the angle of conflict.
