In June 2018, an improvement project began at the interchange with I-280 and CR 508 (Central Avenue). The project involves widening the entrance ramp to the parkway southbound from one to two lanes and adding a second deceleration lane on the parkway northbound. To accommodate the wider roadway, the overpass carrying Central Avenue over the parkway is being rebuilt. Five nearby bridges are also being rehabilitated as part of the project. The project is expected to cost $63 million and be completed in August 2022.
