Boaz puts on a hard hat and a reflective vest to explore the construction site on the Roberto Clemente Bridge for this installment of Yinzer Backstage Pass. Mike Burdelsky, assistant deputy director of the bridge, construction, and contracting divisions of the Allegheny County Department of Public Works, shows us around the site, takes us behind those giant fabric tents and even leads us onto the temporary suspension bridge that they’ve specially constructed under the bridge.

Check out last week’s episode to get a tour of Covestro, the Pittsburgh company who’s probably responsible for your mattress, bowling ball and LEGOs.
