    Hwy. P to Glen Cove Road: ATC has completed the transmission line work, but restoration work along the trail may continue into May 2015 depending on weather and ground conditions. ATC will reopen the trail as soon as it is safe to do so.

    Glen Cove Road to Golf Road: ATC began the pre-construction activities in March 2015 to replace the transmission structures. The trail is expected to be closed through summer 2015.
