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
Final plans, specifications, and estimate have been submitted to MoDOT for approval. Advertising for bids is anticipated in July with a bid opening in August. Construction could start as soon as September 2020.
