Here’s a reminder that the trolley tunnel closes tonight at 10 p.m. for Trolley Tunnel Blitz, a 17-day maintenance and construction project. During this time, SEPTA Trolley Routes 10, 11, 13, 34 and 36 will operate only west of 40th Street. Passengers traveling east of 40th Street can switch to the Market-Frankford subway line at 40th and Market where all the trolleys will divert to. You can also take a bus (Routes 42, 21).

The trolley service in the tunnel is expected to resume on August 18 at 4 a.m. We’ll keep you posted if there are any changes.
