MTA Detours 3 Baltimore Routes for Construction

Three major Baltimore bus routes are running on detours between Fayette Street and Montford Road due to construction work, transit officials said. The Maryland Transit Administration rerouted CityLink Blue, CityLink Orange, and LocalLink 40 starting March 19 at 7:56 PM, with service scheduled to return to normal by 2:00 AM on March 20. The overnight detour affects riders traveling between Johns Hopkins Bayview, West Baltimore MARC, and Essex.

Construction Work Triggers Route Changes

The temporary detour stems from construction work along the regular route corridor, according to Service Alert 26226. Transit officials didn't specify the exact nature of the construction project or which agency is performing the work. The MTA categorized the disruption cause as "Other Cause" in its alert system. Construction-related detours typically require buses to use alternate streets when roadwork blocks normal routes, though officials haven't detailed the specific streets being used for this detour.

Three Routes Share Detour Path

CityLink Blue connects CMS to Johns Hopkins Bayview, while CityLink Orange runs between Essex and West Baltimore MARC station. LocalLink 40 also uses the affected corridor. All three routes are following the same detour path between Fayette Street and Montford Road, transit officials said. The MTA didn't release information about how many riders typically use these routes during overnight hours or how much additional travel time passengers should expect. Officials said the detour affects regular service patterns for all three lines.

Six-Hour Detour Ends Early Thursday

The detour began Wednesday evening at 7:56 PM and is scheduled to end at 2:00 AM Thursday, creating a roughly six-hour service disruption. Transit officials advised riders to allow extra travel time during the detour period. The MTA said passengers can contact the Transit Information Contact Center at 410.539.5000 for route-specific guidance. Officials didn't say whether additional detours are planned for future nights as construction continues.

Riders Can Track Detoured Buses

Passengers using the affected routes should expect temporary changes to stop locations and travel times during the overnight detour period. The MTA provides real-time bus tracking to help riders navigate service changes, though officials didn't specify whether detoured buses will serve temporary stop locations. Moovit offers real-time updates and trip planning for MTA routes, helping riders track detoured buses and find alternate connections during construction-related service changes.
