Project Complete

About the Project

Phase 3, completed in January 2025, focused on improvements in the southwest quadrant of the US 6 and Wadsworth Boulevard interchange to enhance pedestrian connectivity and mitigate traffic noise. Improvements included:

  • Installing 10-to 12-foot-tall noise walls along the frontage road south of US 6 between Meadowlark Drive and the Wadsworth Boulevard off-ramp
  • The noise walls included a concrete guardrail on both sides to protect the wall from errant vehicles
  • Realigning a portion of the southwest frontage road
  • Adding an auxiliary lane along eastbound US 6 from the Carr Street on-ramp to the Wadsworth Boulevard off-ramp
  • Adding a detached 10-foot-wide multi-use path on the west side of Wadsworth Boulevard from just south of 5th Avenue to Highland Avenue north of the interchange
  • Installing pedestrian crosswalks with flashing beacons at five of the on- and off-ramps
