This project will design and construct a new bus rapid transit (BRT) line on MD 355 between Rockville and Germantown. The project includes dedicated BRT lanes, new BRT stations with level boarding and off-board payment, Transit Signal Priority (TSP), purchase of new zero-emission BRT buses, and other associated pedestrian and bicycle improvements along the corridor. In addition, the project includes planning for a new transit center near the Montgomery College Rockville Campus and preliminary design for a relocated and expanded Lakeforest Transit Center to support the project. Planning conducted by the Maryland Department of Transportation Maryland Transit Administration (MDOT MTA) resulted in several alternatives retained for detailed study in 2017 for BRT along MD 355 from Bethesda to Clarksburg. Final design and construction of the North and South segments will occur as a separate project.

Project planning was completed in FY19. Preliminary engineering of the busway was completed in FY24. Environmental documentation for the purposes of submitting for federal funding is underway and will be completed in FY26. Final design will be procured in FY25 and is estimated to last approximately two years. Construction activities, including right-of-way acquisition and utility relocations, may begin as early as FY27. Construction of the BRT is estimated to be completed in FY31, with operations beginning that year.

Cost increase due to extension of project from Montgomery College Rockville to Rockville Metrorail Station and addition of design funding for Lakeforest Transit Center.

MD 355 Flash will transform mobility options with the implementation of a 22-mile, premium, branded, limited-stop BRT service along MD 355 between Clarksburg and Bethesda. This new service will improve transit travel time and increase opportunity for a broad range of users along a highly congested corridor. MD 355 Flash will improve passenger transit mobility by connecting riders to high-density housing and employment centers. MD 355 Flash is being phased to accelerate delivery. This phase will implement BRT between Rockville and Germantown. Extensions to Bethesda and Clarksburg will follow. A new transit center near the Montgomery College Rockville Campus will provide increased space to accommodate both the MD 355 BRT and Veirs Mill Road BRT operations as well as improve overall transit access and operations at this location. The Lakeforest Transit Center is currently undersized for existing operations and a new transit center is being designed in coordination with the Lakeforest redevelopment.

The County intends to secure federal funding for this project through the Federal Transit Administration's (FTA) Capital Investment Grant (CIG) New Starts program. The project was granted entry into the New Starts Project Development process in Fall 2024. Programming of funds through final design and construction improves the project's eligibility for funding.

The amended FY21-26 CIP added $6 M in State grants. Additional State aid in FY23-25 includes State grants for capital projects in Montgomery County programmed and/or preauthorized during the 2022 and 2023 Maryland General Assembly sessions, including $150,000 in the 2023 session specifically identified to support planning and design of a new transit center near Montgomery College in Rockville. $10.23 million of State Aid appropriated to the MD 355 South/North project (P502309) was moved to the this project in FY26.

This project previously assumed funding from Op Lanes Maryland revenue proceeds, which have been pledged by the Maryland Department of Transportation to fund high priority public transit projects in Montgomery County. However, given the uncertainty in timing for that funding source, it was replaced in FY26 with revenue from the State Bus Rapid Transit Fund.

The State Bus Rapid Transit Fund was created by the Maryland General Assembly using State lottery proceeds, and is available to Maryland jurisdictions to fund eligible BRT projects. Long-Term Financing in this project reflects the intention to issue debt backed by this funding source as authorized under State law.

FY24 funding switch from Recordation Tax Premium to Impact Tax to reflect prior year actuals and other adjustments.

A pedestrian impact analysis will be performed during design or is in progress. The County Executive asserts that this project conforms to the requirement of relevant local plans, as required by the Maryland Economic Growth, Resource Protection and Planning Act.
