MD 170 sign
Daytime Single-Lane and Shoulder Closure Scheduled on Northbound MD 170 for Pipe Replacement
(January 12, 2023) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will begin a project this Friday, January 13, to replace an underground pipe on
MD 170 (Aviation Boulevard) between Mathison Way and MD 176 (Dorsey Road) in Anne Arundel County. The work will take place weekdays between 9 a.m. and 3 p.m., and is expected to be complete in late-February, weather permitting.
MDOT SHA’s contractor will close the northbound MD 170 shoulder and is permitted to close a single lane on northbound MD 170 on weekdays when work is underway. Equipment and crews will work from the northbound MD 170 shoulder to access the Stony Run stream.
This work zone is part of the BWI Thurgood Marshall Airport loop. Signs, barrels, and cones will guide drivers through the work zone. Pedestrians and cyclists will continue to have access to the BWI Trail pedestrian bridge during construction.
Maryland’s Move Over Law requires motorists to make a lane change or slow down when approaching any stopped, standing, or parked vehicle displaying hazard warning lights, road flares, or other caution signals. The expanded law is in place to protect emergency responders and motorists who encounter a roadside emergency. Motorists in need may dial #77 on their mobile device for roadside assistance.
