HERRON AVENUE BRIDGE TO TEMPORARILY CLOSE

Published on May 28, 2025

Pittsburgh, PA – Out of an abundance of caution and based on recommendations from structural inspection consultants, the City of Pittsburgh will temporarily close the Herron Avenue Bridge to all traffic beginning at 8:00 AM on Wednesday, May 28.

“Following emergent findings from the City’s bridge inspection consultant and PennDOT, we are moving quickly to close the Herron Avenue Bridge in the interest of public safety,” said Zack Workman, P.E., Acting Chief Engineer. “Barricades and ‘Bridge Closed’ signage will be in place starting Wednesday. A designated detour route will guide motorists via the Bloomfield Bridge.”

The City’s Department of Mobility and Infrastructure (DOMI) is currently in the preliminary engineering phase of a full bridge rehabilitation project, tentatively scheduled to begin construction in 2028. In the meantime, DOMI is collaborating closely with PennDOT and the inspection team to explore options for a safe and earlier reopening.

“Since the start of my administration, I’ve had to make the tough call to close bridges more than once—but I’ve never regretted putting public safety first,” said Mayor Ed Gainey. “Proactive steps like this are how we ensure our infrastructure remains safe for every Pittsburgher.”

Repair plans will proceed following a detailed structural analysis. In the interim, travelers should follow the posted detour:

-Southbound traffic: Southbound detour route will utilize Liberty Avenue to Bloomfield Bridge to Bigelow Boulevard:

-Northbound traffic: Northbound detour will utilize Bigelow Boulevard to Bloomfield Bridge to Liberty Avenue:
