Project Description

US 29 Flash is in Phase 2:

  • Flash on US 29 is currently in service.  For information on current US 29 Flash operations, visit RidetheFlash.com.
  • The Montgomery County Department of Transportation (MCDOT) recently completed construction on a new transit line, the Flash, along US 29.  Flash is a bus-based rapid transit (BRT) system with features that improve reliability, so you can get where you need to go quickly.  US 29 Flash is currently operating between Burtonsville and Silver Spring.  MCDOT recently completed the US 29 Mobility & Reliability Study to identify improvements to the US 29 Flash that would improve corridor travel time, increase pedestrian and bicycle access, and improve reliability for all transportation modes along the corridor.  Based on this study, the median bus lane hybrid alternative has been selected to move into design.
  • MCDOT has initiated work to complete preliminary engineering (35% design) for US 29 BRT Phase 2, which includes the recommended median bus lane hybrid concept.  The study area includes the existing US 29 Flash BRT corridor from Sligo Creek Parkway to Tech Road.  Task order activities will include community outreach, stakeholder engagement, design development, and cost estimate development.

Corridor Advisory Committee (CAC)

Corridor Advisory Committees (CACs) were created in 2015 as part of the Montgomery County Department of Transportation’s (MCDOT) planned Bus Rapid Transit (BRT) service on US 29 from the Burtonsville to downtown Silver Spring. The committee is made up of residents, business owners, and other stakeholders along the corridor. The CAC meetings allow MCDOT to both give updates on the project to members of the community and to gather feedback from stakeholders along this portion of the corridor.

For more information on this corridor, see the Countywide Transit Corridors Functional Master Plan.

The US 29 BRT Phase 2 preliminary engineering project (35% design) is funded through a combination of State and local funding sources. A detailed view of the project funding, budget, and additional data can be found on Montgomery County’s Capital Budget website here.
