February 23, 2017 Update:

Construction of the parking lot and project staging area will continue at 114 Liberty Street. Exploratory excavations will begin along Liberty Street and North Avenue to identify potential project conflicts before construction crews reach these areas. This insures a smooth work progression in the future and avoids project delays.  Residents and businesses can expect temporary, moving lane closures throughout Liberty Street and North Avenue during this locate process. All exploratory excavation areas will be fully backfilled the same day as the work occurs and fully restored as part of the construction contract. All roads will be fully opened at the end of each working day. All work is weather dependent and the timeline and progression may be altered as necessary.
