The bridge at Clarks Pond, which is part of the Lenape Trail is closed. Not sure if/when it will be open. The best detour is to take a right onto Broughton Ave at Demarest Elementary School instead of taking a left. Then a left onto Watchung Ave and a right on Claire St to pick up the trail again at Mohr Ave.
That would be a left onto Watchung and a left onto Clair and a right onto Mohr (just before you hit the soccer fields to your left). You could also just stay on Watchung and the trail joins back up onto Watchung 4 blocks up at the intersection of Clubb St.
