The old Commercial Street Bridge on the Parkway East is history.

Demolition of the Commercial Street Bridge on the Parkway East came suddenly this morning. The explosion happened a few minutes after 8 a.m. followed by a large cloud of dust obscuring for a time what was left of the old bridge. PennDOT's Jason Zang updated reporters about the replacement project at a 10:30 news conference. The closure was expected to last 25 days through August 3rd.

Even with temperatures in the mid 90s, PennDOT says work on the Commercial Street Bridge replacement is moving ahead as planned. District 11 Executive Jason Zang says he's concerned about the safety of crews working in the high temperatures, but says there are no plans to slow or stop the project. Zang says it takes committed men and women to do this kind of work, adding he's proud of the crews for pushing forward while making safety the top priority.

Things are going rather smoothly on this first business day of the Parkway East closure.

This morning, we saw the full extent of the Parkway East shutdown on morning drive traffic. Many expected Oakland would see a lot of detour congestion, but on the Big K Morning Show, Michael Bartley told PennDOT's Jason Zang is wasn't much of a problem. The demolition of the Commercial Street Bridge will take place this week.
