6/7/2010MD 725 Bridge over Federal Springs Branch Rehabilitation Project




SHA Will Replace the Existing Bridge on MD 725 in Prince George’s County;

Project Made Possible Through ARRA Funding


Next week, the Maryland Department of Transportation’s State Highway Administration (SHA) will begin a $2 million bridge replacement project on MD 725

(Old Marlboro Pike) over Federal Spring Branch in Upper Marlboro, Prince George’s County.  Weather permitting, construction will be complete summer 2011.


The project includes removing and replacing the existing bridge with a wider structure that will accommodate a new 558 foot sidewalk and 5 ½ foot wide shoulders.   Other work includes constructing a new temporary bridge and approaching roadway, reconstructing 940 feet of the roadway leading up to the existing bridge, installing new pavement markings, and a temporary stream diversion through two 66-inch pipes.  The stream diversion work must be complete before any other work can begin.


During construction, crews will close the existing MD 725 Bridge and all traffic will be shifted to a temporary bridge located eight feet north of the existing bridge.  The temporary bridge will maintain both lanes of traffic during construction.   SHA will first complete the stream diversion work between June and September 2010.  Once the stream is diverted, SHA can begin work on the temporary bridge.  It is anticipated that traffic will be shifted to the temporary bridge fall 2010 and the existing MD 725 Bridge will be closed until summer 2011.


The MD 725 Bridge, originally built in 1928, serves the local traffic of Upper Marlboro and routinely floods during periods of heavy rain.  This project is part of SHA’s bridge preservation and replacement program.


When construction on the temporary bridge begins, drivers will encounter single lane closures Monday through Friday between 9 a.m. and 3 p.m., and overnight Sunday through Thursday between 9 p.m. and 5 a.m.


The contract was awarded to Chevy Chase Contractors, Inc.  SHA will provide variable message signs, jersey barrier wall, drums, and arrow boards to guide motorists through the work zone. 


When workers are on the road, THINK ORANGE, which is the color of construction signs, barrels and warning devices.  Please slow down, stay alert and expect the unexpected.  Choose to make work zone safety your business at
