Westbrook ? Motorists traveling in the vicinity of the Cumberland Street bridges spanning the Presumscot River in Westbrook need to be aware of traffic delays effective immediately. Crews have initiated a tree removal operation that will continue through Saturday evening, Jan. 7th. Alternating one way traffic will cause delays, therefore motorists are advised to allow extra time or seek an alternate route. This tree removal work is being done in advance of building a temporary bridge that will be used during the replacement of the Westbrook Cumberland bridges.
