The City of Clinton would like to provide an update on ongoing construction activities associated with the South Bluff Boulevard improvement project.
College Avenue & South Bluff Boulevard Closure
The intersection of College Avenue and South Bluff Boulevard is scheduled for reconstruction beginning August 31, 2026, through September 21, 2026. During this time, the intersection will be closed to all traffic.
Motorists are encouraged to use the designated detour routes, including:
2nd Avenue South to South 4th Street, Mill Creek Parkway
The purpose of this closure is to complete all remaining underground utility work and street paving at the intersection. Completing this work now will ensure that the intersection will not require an additional closure later in the South Bluff Boulevard project.
