​Drivers Advised to Remain Alert for Daytime Flagging Operation; Signal Activation Scheduled for Spring Completion 

(February 13, 2024) – The Maryland Department of Transportation State Highway Administration will begin construction this month for the new traffic signal on MD 179 (Saint Margarets Road) at the Pleasant Plains Road / Old Mill Bottom Road intersection in Anne Arundel County. Starting Wednesday, February 14, State Highway Administration crews will begin work using a flagging operation on weekdays during off-peak hours. 

The new signal will alternate access between traffic along MD 179 and traffic entering from Pleasant Plains Road and Old Mill Bottom Road. The signal is equipped with cameras that will detect and efficiently regulate traffic flow on MD 179 between the two side streets – when the Pleasant Plains approach receives a green indicator to move traffic through the intersection, the Old Mill Bottom approach will be stopped with the red indicator. Then, Old Mill Bottom Road will receive the green indicator and Pleasant Plains will get the red.

Additional work will include upgraded signing and new pavement markings. Contractor McClean Contracting Inc., of Glen Burnie, will use a flagging operation, temporary traffic signs, barrels and cones to guide motorists through the work zone. Construction completion and signal activation is expected in the spring, weather permitting.

The State Highway Administration appreciates customer’s patience during this necessary work to maintain and improve the transportation system. Drivers are asked to stay alert, stay focused, look for reduced speed limits as well as driving pattern changes and slow down in construction zones. Motorists in need may dial #77 on their mobile devices for roadside assistance.
