The SEPTA Trolley Tunnel that connects West Philadelphia with Center City will close for more than two weeks beginning Friday, July 9, which means that trolley routes 10, 11, 13, 34, and 36 will temporarily divert to 40th and Market. The annual trolley tunnel maintenance/construction project, “Trolley Tunnel Blitz”, will begin at 10 p.m. on Friday and continue until Monday, July 26, at 5:00 a.m.

During the “Blitz”, trolleys will continue operating in West Philadelphia. SEPTA customers may transfer to the Market Frankford Line at the 40th Street station (40th and Market) at no additional charge.

This year, tents will be available as a temporary shelter for customers transferring from trolleys/Market Frankford Line. For late night travel, customers can transfer to Market-Frankford Line Night Owl bus service.

Maintenance and construction work during this year’s “Blitz” includes demolishing and rebuilding the full length of the eastbound 22nd Street platform, replacing worn curved rail at 37th Street eastbound and 15th Street westbound, and other projects. SEPTA crews will also do some heavy cleaning and improvement at underground stations, including painting, lighting, and graffiti removal.
