Construction picked back up on the Cooper Landing Bypass Project this week, and the state is cautioning motorists to be aware of flaggers and delays along the affected portion of the Sterling Highway. Construction on the project paused in October for the winter.

The Alaska Department of Transportation and Public Facilities shared in a social media update Tuesday that construction season on the Sterling Highway MP 45-60 project, also known as the Cooper Landing Bypass Project, began Monday. Motorists, the department said, should expect single-lane closures between Mileposts 56 and 58 of the Sterling Highway, as well as detour routes and flagging operations.

The project, when completed, will add 10 miles of road starting at about Milepost 46.5 off the Sterling Highway and is meant to reduce congestion through Cooper Landing. The new section of highway will cross Juneau Creek via a steel arch bridge before rejoining the highway around Milepost 56. Construction is already underway, with final completion tentatively scheduled for 2027.
