Why are road crews doing this on I-279?

If you happened to see the lane closure markers and road crew vehicles, you still may have missed this on I-279 Monday morning.

Video captured from the shoulder shows two men on tiny roller seats, rolling around and pounding on the concrete with hammers.

If you are wondering what they’re doing and why, you are not alone.  Seeing this piqued the curiosity of our head “Rabbler”.  We have reached out to PennDot for an answer.

Thanks for PennDOT District 11 Media Contact Steve Cowan for sharing the following news release from last week.

He says he will try to find out some specifics and get back to us once he has a better answer.

We’d love to hear your thoughts.

Share them on Facebook and Twitter and maybe give us a “Like” and/or a “follow”.
