Philadelphia, PA: SEPTA will be closing the Subway-Surface trolley tunnel for a full month starting today, July 11th 2025 at 10 pm, to perform extensive maintenance.
This means all stations east of 40th Street on the SEPTA Metro 
and 
lines will not be served. In this event, all 
lines will be diverted to serve 40th St on the 
Lines to allow for passengers to continue via free transfer to the SEPTA Metro 
for Center City stops. The closure of the trolley tunnel for maintenance during the summer is referred to as the Trolley Tunnel blitz.
The reason why this year’s Tunnel Blitz is longer than previous years Trolley Tunnel Blitzes, is because this year PennDOT will also be working on the tunnel under the Schuylkill River.
The Following stations will not be served by any SEPTA Metro Service:
- 40th St Portal
- 37th-Spruce
- 36th-Sansom
- 36th St. Portal
- 33rd St
- 22nd St
- 19th St
However, service on the following stations will continue to be served by trains (despite not being served by SEPTA Metro lines):
- Drexel Station at 30th
- 15th Street
- 13th Street
Passengers getting off at any of the unserved stations are urged to transfer to nearby bus service. The graphic below provided by SEPTA is meant to assist with navigating the system.
Due to the amount of events that are due to take place next year, there will be no Trolley Tunnel Blitz in 2026.
That means this year, being the thirteenth year of the annual Trolley Tunnel Blitz, will end the streak of the blitz taking place every year.
