MOUNT DESERT — Pre-construction work has begun on the project to replace the bridge over Stanley Brook on Route 3 at the beach in Seal Harbor.
Alternating one-way traffic over the bridge will begin on Sept. 6, and the beach parking area will be closed so it can be used as a construction staging area.
Starting Sept. 19, Route 3 at the bridge will be closed to all traffic for up to five weeks. Traffic will be re-routed onto Jordan Pond and Stanley Brook roads.
