A Butler County farmer says local produce is safe as health officials investigate 11 cases of cyclosporiasis.

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.

A Butler County farmer says local produce is safe as health officials investigate 11 cases of cyclosporiasis. The Allegheny County Health Department has confirmed 11 cases of sye-clo-spor-eye-uh-sis and is investigating whether they're connected. The illness is linked to contaminated food or water and is not spread from person to person. Sorgel's Orchard's Adam Voll, a sixth-generation Butler County farmer, tells the Big K Morning Show consumers shouldn't be afraid to buy fresh, locally grown produce. Health officials say anyone experiencing symptoms should contact their healthcare provider, while Voll reminds shoppers to thoroughly wash fresh produce before eating or preparing it.

Even with temperatures in the mid 90s, PennDOT says work on the Commercial Street Bridge replacement is moving ahead.

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.
