Rockland Detour 

(WABI) – Downtown Rockland was restricted to one lane Tuesday morning, after part of the town’s retaining wall gave way Monday night.

Authorities say a large portion of the wall fell off, damaging Main Street.

A minor tear has been found in the road so far, and there’s concern the undermining might continue.

Knox County Sheriff’s dispatchers say they expect delays throughout the day Tuesday…and are advising drivers to find alternate routes through downtown Rockland.
