Allen Road, between Alta Road and Hickory Grove Road, will be reopened to traffic Thursday afternoon.
Motorists are advised to use caution and watch for new traffic signals at the intersection of Allen and Wilhelm Roads.
With the opening of Allen Road, however, comes the closing of a portion of Wilhelm Road.
Wilhelm Road, from Allen Road to Northfield Lane, will be closed for Phase 2 of the construction project.
This portion of Wilhelm will only be accessible to local residents and emergency crews.
Wilhelm is expected to reopen in November.
