Drivers affected by the closure will be detoured using Merrimack Street, Parker Street, Amesbury Street, Lawrence Street and Essex Street to the adjacent river crossing at the Casey Bridge. Traffic leaving from the area of the Lawrence General Hospital will be detoured using Prospect Street, Marston Street and the lower portion of the double decker O’Reilly Bridge to Merrimack Street.
Construction began on the $19.9 million project in April 2009. Crews have relocated utilities located on the existing bridge and completed other advance work items in order to minimize the duration of the closure.
This project is part of MassDOT's Statewide Road and Bridge Program. Further changes to the detours and traffic set ups will be announced in advance. The project is expected to be completed in Spring 2013. Temporary signs and Variable Message (VMS) Signs will alert drivers to the changes and detour route.
