New RTA Route 405 Service

Route 405 has been restructured to provide more local service throughout Ellicott City, including Old Ellicott City. The restructured 405 service provides connections to the new 505 route, serves as a circulator in Ellicott City, and adds service to Pine Orchard Apartments and the Goodwill Store.

New RTA Route 505 Service

Route 505 will provide stops in Catonsville, Columbia and Ellicott City. It will originate in Downtown Columbia with stops at the Long Gate Shopping Center and other destinations in Ellicott City, and then travel into Baltimore County with a stop at the Catonsville Walmart off US 40 and North Rolling Road. This stop in Catonsville will create a new connection between RTA and MTA service, while also complementing MTA’s existing Express Bus 150 service and its plans to improve bus service between Catonsville and Baltimore City later this year.

Complete Streets Policy Implementation


Howard County has adopted a Complete Streets Policy and is developing a Complete Streets Design Manual to be completed by October 2021. These initiatives were recommended in both the Howard County General Plan (PlanHoward) and the Howard County Bicycle Master Plan (BikeHoward), and were required by the adoption of Council Resolution 35-2016.


Go Howard


Transportation Demand Management is moving people, not vehicles, and creating a more efficient use of our roadways.  It's providing and encouraging Transportation Options for those who want them such as biking, walking, taking the bus or train, commuting at non-peak hours/days or even the commute you don't make: working from home. Go Howard is the Transportation Demand Management (TDM) program of Howard County, Maryland, funded by the Maryland Department of Transportation -- Maryland Transit Administration and the Howard County Office of Transportation.


Regional Transportation Agency


The Office of Transportation manages and oversees the contract under which the Regional Transportation Agency (RTA) provides fixed route bus and paratransit services in Howard County, Anne Arundel County, Prince George’s County and the City of Laurel. Funding is shared by the partner jurisdictions with support from federal and state sources to offset the gap between farebox and other revenues and capital and operating costs. The RTA runs 15 fixed routes, provides complementary paratransit service to people with disabilities, and general-purpose transportation for both elderly people and people with disabilities.


Transit Development Plan


The Howard County Transit Development Plan (TDP) is a short-term (typically a five-year period) plan to guide transit system development. The TDP provides a vision of the future public transportation system.


Transportation Studies & Projects


The Office of Transportation coordinates closely with the Department of Planning and Zoning, the Department of Public Works and state agencies to develop transportation plans and projects for all modes.
