Phase 4 Improvements

Phase 4, the final phase of the overall project, will construct the following improvements:

  • Replace the US 6 bridge over Wadsworth Boulevard;
  • Change the interchange configuration from a cloverleaf to a diamond interchange with a loop ramp in the northwest quadrant. This will remove the loop ramps in all other quadrants and replace them with new longer on- and off-ramps;
  • Lengthen on-ramp acceleration lanes;
  • Realign the frontage road in the northeast and northwest quadrants to accommodate the diamond ramp configuration;
  • Widen Wadsworth to three lanes in each direction under the interchange to match the roadway north and south of the interchange;
  • Construct a detached 10-foot-wide shared-use path along both sides of Wadsworth to connect to existing paths north and south of the interchange built in the prior phases;
  • Improve crosswalks and add push-button-activated flashing beacons at unsignalized ramp crossings;
  • Install crosswalks with pedestrian-activated flashing beacons at free-right turn movements of the on-ramps and off-ramps;
  • Add a pedestrian underpass at the US 6 loop ramp to provide continuous safe pedestrian access along the west side of Wadsworth;
  • Add a westbound auxiliary lane on the north side of US 6 between the US 6 on-ramp and Carr Street off-ramp;
  • Add noise walls in the northeast, northwest, and southeast quadrants of the interchange along US 6 and Highland Avenue;
  • Add new curb, gutter, and storm sewer throughout the improvement area.

Construction on Phase 4 began in October 2026 and will conclude in late-2029.
