Beginning at 7 a.m. Monday, work crews from Miller Pipeline Co. will be rehabilitating a sanitary sewer main in Alley 1-130, which runs from Jonathan Street, behind University Plaza, to the North Potomac Street parking deck.
That section of the alley will be closed to all vehicular traffic.
Vehicles will still be able to reach the rear of the parking deck using Alley 1-135, Hays Alley, beside the University of Maryland.
The contractor expects that the alley will remain closed until the work is completed on Wednesday morning.
Emergency vehicles will not be able to pass through this alley while the work is being performed.
