Slip ramps will be added between North and South St. Peters Parkway and MO-364 to improve connectivity between Heritage Crossing and the freeway. The westbound on-ramp would include a parallel-type acceleration lane that would end prior to the MO-364 overpass over Jungs Station Road. The eastbound off-ramp would similarly include a parallel-type deceleration lane on MO-364 beginning after Jungs Station Road. Lane widening, retaining wall adjustments and signal modifications will likely be required to accommodate the new ramps
MoDOT has received and reviewed the plans, specifications and estimate documents. A resubmittal will be necessary, which is planned for June 2020. Advertisement for construction bids could come as soon as July 2020.
