​Drivers Advised to Plan for Extra Travel Time on MD 30 During Construction

(December 9, 2022) – The Maryland Department of Transportation State Highway Administration (MDOT SHA), the Maryland Department of Emergency Management (MDEM) and the Maryland National Guard (MNG), will improve the intersection of MD 30 (Hanover Pike) at Rue St. Lo Drive in Reisterstown.  Weather permitting, the work will begin Monday, December 12 and be complete spring 2023.

Contractor crews will perform roadside slope rehabilitation and highway drainage improvements, construct new curb and gutter, upgrade traffic barriers and mill and resurface the pavement at the intersection. Motorists can expect daytime single lane closures on MD 30 with flagging operations in effect between 9 a.m. and 3 p.m., Monday through Friday. The lane closures will be suspended on Monday, December 26, and Monday, January 2, 2023, for Christmas and New Year’s.

MDOT SHA contractor Concrete General, Inc. of Gaithersburg will perform the work on this $500,000 project, which was funded by the Department of General Services (DGS).  Customers who have questions about the work on MD 30 may contact the MDOT SHA District 4 Office Construction Division at 410-229-2300 or toll-free at 1-866-998-0367.

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.
