2025 Construction Plans
Work is scheduled to resume in spring 2025, with project completion targeted for late 2025.
Next year’s construction will concentrate on completing the retaining wall near Nassau Creek, intersections with Highway 4 at the Pool Station Road and Appaloosa Road, as well as the northern end (final 1 mile section) of the new, realigned Highway 4 mainline.
When work restarts, a temporary closure will be necessary to reconfigure the intersection of Highway 4 and Pool Station Road. Specific details, including dates, times, and detour routes will be provided as they become available.
