A parking lot under the Interstate 95 underpass on Riverside Avenue (Lot No. 6) will be closed from Saturday to approximately Sept. 4, as work crews replace a retaining wall, repair storm drains and repave the lot, according to Deputy Police Chief Foti Koskinas.

The parking lot on the opposite of Riverside Avenue (Lot No. 5) that has been closed since Aug. 5 is scheduled to reopen Saturday.
