Open Houses were previously held in late January/Early February 2018 to educate the public and gather community input on the MD 355 project. Click here for the Open House materials (29MB) or here for the virtual open house.


  • The MD 355 Bus Rapid Transit (BRT) will provide upgraded, frequent, and reliable service between Downtown Bethesda and Clarksburg along the MD 355 (Wisconsin Avenue/Rockville Pike/Frederick Road) corridor.
  • The Montgomery County Department of Transportation (MCDOT) is studying different alternatives for the MD 355 BRT. Upon completion of the study, MCDOT will identify a single “Recommended Alternative” – which includes the BRT route, station locations, and engineering features – that can be advanced toward design and implementation in phases.
  • The MD 355 BRT will be part of the County’s Flash BRT system with amenities like upgraded stations, real-time information, free Wi-fi, and quick boarding features.


The new BRT service on MD 355 between Bethesda and Clarksburg will be designed to meet the needs of residents, businesses, and visitors along this busy route. This project is part of the Countywide Transit Corridors Functional Master Plan.

There are several major existing and planned activity centers along the MD 355 corridor that have importance for the entire county and region. The MD 355 BRT will improve frequent transit connections between the corridor and destinations within Montgomery County and other parts of the region.


Over the past decade, MCDOT and the Maryland-National Capital Park and Planning Commission, as well as the Cities of Gaithersburg and Rockville, have completed land use and transportation studies advancing the concept for the BRT, and supporting the vision of transforming the corridor into a series of walkable and prosperous nodes of commercial, residential, and civic land uses and activities.

From 2015 to 2017, the Maryland Department of Transportation (MDOT) conducted a study (“Phase 1”) to identify options for the MD 355 BRT. Through that study, MDOT identified several options, called Conceptual Alternatives, for the BRT. MCDOT is now leading Phase 2 of the study, which involves further study and evaluation of the Conceptual Alternatives from Phase 1 to identify one Recommended Alternative for the BRT.


To identify the Recommended Alternative in Phase 2, MCDOT will be looking at various alternatives, addressing whether and where the BRT should run in a dedicated median or curb lane or in mixed traffic, which route it should take, and which stations should be included in the Recommended Alternative. The alternatives will be evaluated according to a set of criteria that address considerations such as travel times and reliability, ridership, accessibility to jobs and other destinations, support for redevelopment, costs, and impacts to the environment and properties. MCDOT is also developing a preliminary service plan for the BRT and complementary local bus routes.

For more information about the alternatives MCDOT is studying in Phase 2, see MD 355 Alternatives.

The BRT’s features and amenities will include:

  • Frequent, reliable service
  • Dedicated lanes, where feasible
  • New, enhanced vehicles that accommodate bicycles onboard and are equipped with Wi-Fi and USB ports
  • New, comfortable stations that provide weather protection, pre-payment stations, and real-time transit information (via message boards)
  • Community-friendly design with enhanced pedestrian and bicycle facilities
  • Level boarding through all doors, allowing for easy boarding and alighting for all riders, including those in wheelchairs
  • Transit Signal Priority (TSP) to support faster and more reliable BRT operations


Local governments, stakeholders, advisory committees, and the public have been involved in the project since 2015, and their input will continue to be sought during this Phase 2 study. To get involved and stay informed about the project, you can:

Other BRT routes in the County that are currently being considered or designed include:


RELIABLE Frequent service, dedicated lanes, and green light priority signaling keep BRT vehicles moving.

EFFICIENT One BRT vehicle can take up to 90 cars off the road, making our transportation network more efficient and your commute easier.

CLEAN BRT reduces harmful greenhouse gas emissions, making our air cleaner.

COMFORTABLE New BRT stations will feature real-time travel info and provide a place for you to wait comfortably and pay your fare before boarding.

COST-EFFECTIVE You can save money by riding BRT instead of driving a car.
