The National Park Service is moving to pull out the protected bike lane on 15th Street that cuts through the National Mall, turning that federal stretch back over to motor-vehicle lanes. The decision has local riders and advocacy groups on edge and has set up a tense back-and-forth over who really calls the shots on the Mall's streets.
What the Park Service ordered
As reported by Axios, the National Park Service will remove the portion of the 15th Street protected bike lane that sits inside the National Mall and convert the roadway from Constitution Avenue through the Tidal Basin back to car traffic beginning Monday. Because the Park Service controls that land, NPS crews, not the District, are carrying out the switch. The removal cuts what had been a continuous protected corridor linking downtown to the monuments.
Park Service frames move as event and safety work
NPS told Axios the conversion is tied to major events and Mall maintenance. "With the upcoming National Cherry Blossom Festival and preparations underway for America's 250th anniversary, ensuring safe access for residents, commuters, visitors, and emergency services is a shared priority," the agency said in comments reported by Axios. The Park Service has also been overseeing construction and landscape work around the Tidal Basin that will keep parts of West Potomac Park in a temporary state of flux through the spring.
What DDOT's evaluation found
A city before-and-after review of the 15th Street project showed sharp safety gains once the protected facility went in, including a reported 46% drop in all roadway crashes and a 91% reduction in bicycle injury crashes, according to a local summary of DDOT materials. That evaluation was highlighted by neighborhood outlets that linked out to the agency's online documents and maps. PoPville summarized the findings and directed readers to DDOT's posted materials.
Advocates mobilize
Local groups say the call was abrupt and unnecessary, and they are organizing in response. The Washington Area Bicyclist Association has labeled the change "federal meddling," says it is exploring legal options, and has urged volunteers to keep an eye on the corridor. WABA previously helped stage protest rides when talk of removal first surfaced in February. WABA has been one of the most visible voices pushing back on the move.
Big events could mean more temporary changes
The Mall's packed 2026 calendar helps explain why agency staff are reworking streets. Organizers are planning the National Cherry Blossom Festival and an America 250 lineup of events, including the Freedom 250 Grand Prix on the Mall later this summer, which is slated to use stretches of Pennsylvania Avenue and nearby streets. The official America 250 event calendar lists the Freedom 250 Grand Prix on the Mall for Aug. 21–23, a weekend expected to require major street staging, according to DC250.
Rider options and what to watch
Cyclists who rely on the Mall corridor will need to shift to parallel downtown routes and watch for posted detours. DDOT bike maps show nearby protected and lower-traffic streets that can absorb displaced riders while the Park Service makes its changes. Riders should keep an eye on DDOT and National Park Service notices for the official closure timeline and any short-term mitigation plans. DDOT.
