Roundabout on Dennis Avenue at Proctor Street in Silver Spring

The purpose of this notice is to inform you of an upcoming traffic improvement project in your neighborhood. Montgomery County Department of Transportation (MCDOT) proposes to modify the existing intersection by constructing a new traffic roundabout. The new traffic pattern resulting from the roundabout construction is anticipated to improve traffic safety for motorists and pedestrians.

This project was developed to address community concerns related to traffic safety and operation along Dennis Avenue between MD 193 (University Boulevard West) and Sligo Creek Parkway. MCDOT evaluated conditions along Dennis Avenue and developed a design concept for the proposed roundabout, which was presented to residents at a virtual meeting on October 14, 2021.

The roundabout design concept plan is attached. Construction will primarily occur within the existing County right of way boundaries, minimizing the project’s impact on adjacent properties. Limited, temporary construction easements must be obtained at 740, 816, and 820 Dennis Ave to complete reconstruction of the driveways and sidewalks. At the completion of construction, all disturbed areas will be graded and restored using grass seed, topsoil, and straw. Excavated sidewalk will be replaced in kind and all affected residential driveway aprons will be reconstructed. Dennis Avenue will remain open to traffic during construction using a flagging operation (see the attached Flagging Control schematic, for example), but will include brief periods of full road closures that may last up to two hours.

MCDOT appreciates your patience and understanding as this project advances. If you have any questions or comments, please contact Michael Baccari, Project Manager at [email protected] or 240-777-2190.
