PITTSBURGH (KDKA) – The Parkway East will be closed all weekend and PennDOT is suggesting you avoid the detour route.

PennDOT District 11 Executive Cheryl Moon-Sirianni says when they used this same detour during the rebuilding of the Squirrel Hill Tunnel, “The detours were in the time frame of an hour, to two hours, upwards some times to three hours.”

Those kinds of delays are possible this weekend because all the Parkway Traffic will be detoured down Forbes Avenue through the heart of the Oakland Business District.

After a jog over to Fifth Avenue, the detoured traffic will make a right onto Penn Ave in Point Breeze and into the single lane run through the Wilkinsburg business district.

“We do want you to avoid the Parkway, and the detour routes do have a lot of traffic signals on them,” Moon-Sirianni says.

In fact, there are 41 traffic lights on the detour route.

Moon-Sirianni says there will be police officers strategically placed to keep traffic rolling.

“I don’t want to say smoothly, just it can keep it moving,” she says.

With PennDOT suggesting you avoid the area, here are a couple of alternatives to consider.

If you are trying to reach Kennywood, you could use Carson Street out of the Southside and follow Rt 837 all the way to the park.

You could also take Second Ave out of downtown and go up through Greenfield to the Homestead Grays Bridge.

And if your destination is to Monroeville or points east, PennDOT suggests you use Route 28 to the Pennsylvania Turnpike and back down to Monroeville.

The work will wrap up and the Parkway East will reopen just in time for Monday morning rush hour.

While the contractor has until 5 a.m. Monday morning, they will reopen the road earlier if the work is finished.

PennDOT says they are squeezing two weekends worth of work into this weekend so they can finish up the project and reduce the inconveniences to drivers.
