Work on the first of Atlantic Crossing’s two blocks is underway, with activity staged to minimize inconvenience for neighbors and visitors. Excavation has begun for the first underground garage. A covered walkway is in place along NE 6th Ave. for pedestrian safety. FPL, Comcast and AT&T are relocating old utility lines so new lines can be underground. The only street closure is NE 7th Ave. north of NE 1st St., implemented at Palm Trail neighbors’ request, with bike and pedestrian access remaining open.
