Pittsburgh drivers, brace yourselves—major I-579 bridge repairs are about to shake up your commute! Expect new traffic patterns, ramp closures, and detours starting Sunday as crews fix deteriorating bridge piers. The southbound I-279 to I-579 route will shift into HOV lanes, and several ramps (including Route 28 to I-579) are closing. Only two lanes will stay open, so plan for delays and check detours before you hit the road. Northbound changes are coming later! #Transportation #PittsburghTraffic #Roadwork
