Overnight parking restrictions are in place in portions of the MBTA’s Alewife Station parking garage in Cambridge to make way for repair work that started last month.
Rockland-based Heritage Restoration Inc. is doing almost $3 million in work at the garage, including repairs to concrete columns and beams, removing and replacing expansion joints, replacing damaged skylight panels, and repairing broken drain pipes, according to the MBTA.
Alewife is the westernmost stop on the Red Line.
The work is expected to continue until March 2014, according to the MBTA’s website. Most of it will be done during the overnight hours, and the garage will remain open during construction.
But in order to complete the work on schedule, the contractor is allowed to close up to 250 of the facility’s 2,700 parking spaces, according to MBTA spokesman Joe Pesaturo.
Heritage Restoration has blocked off 125 spaces on the fourth and fifth floors of the garage for repairs to the concrete decking on both levels, with the work in those sections expected to be finished by next Friday.
Blocking off the parking spaces protects motorists and their vehicles from debris falling from the reconstruction work, Pesaturo said.
Heritage Restoration is also beginning the cleaning and inspection of the Alewife garage’s draining system, according to the MBTA.
The work is being done between 10 p.m. and 5 a.m., and Pesaturo said during the day there is sufficient capacity in the garage to accommodate vehicles.
