The Town of Erie, working with the City of Lafayette, is making improvements along Arapahoe Road to keep traffic moving safely and efficiently as the area grows. Crews will begin installing new signal equipment the week of Sept. 8, with updated timing plans in place by the end of the month. Additional work includes lane striping changes to improve turn movements and a project in late 2025 to widen 111th Street at the Arapahoe intersection by adding new northbound and southbound left-turn lanes.

Explore the map below to see the locations of each improvement and learn more about what’s happening at each spot along the corridor.
