This project provides for planning and reconstructing various existing intersections in Montgomery County and for an annual congestion study to identify locations where there is a need for congestion mitigation. The project also includes the identification and implementation of corridor modifications and traffic calming treatments to enhance pedestrian safety. At these identified locations either construction begins immediately or detailed design plans are prepared and developed into future projects. The projects listed below reflect their current status

Cost Change

Increase due to the addition of FY19-20 to this ongoing level of effort project partially offset by capitalization of prior year expenditures.


Ongoing studies conducted by the Traffic Engineering and Operations Division indicate that many corridors and intersections need modifications implemented to calm traffic while improving capacity and/or vehicular and pedestrian safety.


Examples of recently completed projects: Arcola Avenue, MacArthur Blvd at Wilson Road, Wisteria Drive between Great Seneca Highway and Waring Station Drive, Middlebrook at Great Seneca Highway, Bradley Boulevard at River Road, Southlawn at East Gude Drive, Randolph Road at New Hampshire Avenue, Dale Drive between US 29 and Wayne Avenue, Glen Mill Road at Boswell Lane, Wightman Road at Montgomery Village, Emory Lane at Norbeck Road, Spartan Road from MD 97 to Appomattox Road, Homecrest Drive from Bel Pre Road to Longmead Crossing, Cedar/Summit between Saul and Knowles Avenue and Brunett Avenue from Forest Glen Road to Sligo Creek Parkway. Projects scheduled for completion in FY14 and beyond are: Sam Eig Highway from Great Seneca Highway to Diamondback Road, Midcounty Highway at Shady Grove Road, Plyers Mill Road from MD 97 Kensington Town Limit, Lockwood Drive from MD 650 to US 29, Wickham Road from Blue Bell Lane to Olney Mill Road, Longdraft Road between Great Seneca Highway and Clopper Road, Plyers Mill Road at Metropolitan Avenue, Montrose Parkway at East Jefferson Road, Democracy Blvd at Seven Locks Road, MacArthur Blvd at Sangamore, and several small undesignated projects.

Fiscal Note
