By MyFM's Rick Michaels - Construction resumed earlier this month and work continues on the Washington Street Corridor Improvements Project in downtown Holliston. Underway is installation of foundations within the existing sidewalks for the huge traffic signal arms that overhang Washington Street. In a project update released yesterday, once that work is complete the contractor will begin to install new curbing along portions of Washington Street. That will require some temporary sidewalk restrictions with some restrictions on parking downtown. However, access to businesses will be maintained at all times as the month of May draws closer. Milling and repaving of the roadway is expected to begin.
