McComas Avenue Neighborhood Greenway

The McCommas Avenue Neighborhood Greenway project aims to improve pedestrian and bicyclist safety on McComas Avenue near Wheaton Mall. The project limit is from St. Paul Street to Georgia Avenue including portions of Douglas Avenue and Windham Lane.

McCommas Avenue Neighborhood

Neighborhood Greenways are streets with low motorized traffic volumes and speeds, designed and designated to give walking and bicycling priority. McComas Avenue was designated a Neighborhood Greenway by the 2018 Montgomery County Bicycle Master Plan . Neighborhood Greenways use signs, pavement markings, and speed and volume management measures to calm traffic and discourage through trips by motor vehicles to create safe, convenient use of streets by pedestrians and cyclists. Design elements can include traffic diverters at key intersections, traffic circles or mini-roundabouts, traffic calming, shared lane markings, crossing improvements, and wayfinding signage to guide bicyclists along the route and to key destinations among other things. More information about the difference types of improvements can be found here .

November 2022 Updates

In order to better serve the needs of the community, MCDOT seeks public input throughout the project. MCDOT is conducting a community survey to assess the specifics of improving pedestrian safety on Upton Drive. Results will be used to guide the direction of this study, such as current concerns related to roadway safety, ideas of improvements, and community pedestrian and bicyclists needs.

Your participation before January 9, 2023 will be greatly appreciated.

What is a neighborhood greenway?

A Neighborhood Greenway is a street where the safe movement of bicyclists and pedestrians is prioritized, and the fast, through movement of vehicles is minimized. This is achieved by using different treatments to slow down drivers or discourage them from using the street. Tools can include speed treatments such as speed humps and diversionary treatments.

What are "speed treatments"?

Speed treatments are traffic calming tools added to the street that encourage motorists to drive more slowly. They can include things like "chokers" that make the road narrower, "chicanes" that introduce a weave to the roadway, and “mini-roundabouts” that require drivers to move through intersections more slowly. These are just a few examples:

What is “access management?”

Access management refers to treatments installed to reduce drivers’ ability to move through the network. Treatments can include making a street one-way at the end of a block, installing a median so that drivers can only turn right at an intersection, or full closures for portions of the street. Other tools are available. This is only a sample of treatments
