Pittsburgh’s annual summer festival dedicated to pickles, Picklesburgh, is an even bigger dill this year, with an additional day of festivities between July 16-19 and an expanded footprint that now includes Downtown’s new Arts Landing complex.

Pittsburgh Regional Transit has had to adjust its bus routes accordingly, with detours that begin days before the festival and end days after to account for setup and teardown.

From Sunday, July 12 to Tuesday, July 21, all bus routes that typically traverse the Roberto Clemente Bridge, the Andy Warhol Bridge, or Fort Duquesne Boulevard between Seventh Street and Stanwix Street will instead use the Rachel Carson Bridge.

The bus stop at Sandusky Street and Isabella Street on the North Shore will also be inactive during this time.

The following routes will be affected:

• 1-Freeport Road

• 2-Mount Royal

• 6-Spring Hill

• 8-Perrysville

• 11-Fineview

• 12-McKnight

• 13-Bellevue

• 15-Charles

• 16-Brighton

• 17-Shadeland.

Fourth Avenue will close between Stanwix Street and Wood Street from Tuesday, July 14, to July 21. These bus routes will take a detour via Liberty Avenue, Sixth Avenue and Smithfield Street:

• 51-Carrick

• 52L-Homeville Limited

• 53L-Homestead Park Limited

• 54-North Side-Oakland-South Side

• 58-Greenfield.

Those interested can view a full map of Picklesburgh on the festival’s website to plan their commutes.
