Traffic on East Main Street has been diverted to one lane just before South Fifth Street in front of the Post Office, after city crews noticed a depression in the asphalt following some rain and snow last week. WYDOT Public Relations Specialist Cody Beers said a four-inch void was discovered under the concrete at the spot.

“We knew that the road was swampy in that area but the police department closed it, and the city put up the barriers,” Beers explained. WYDOT officials are working to find a company that is available to rehab the section now.

Beers said the likely solution is something called “slab jacking” that involves pumping a substance — even styrofoam can be used — to fill the void. That would stabilize the roadway and avoid the need to tear up the street just as winter weather begins.

The roadway was constructed in 2004, and crews first noticed a depression forming along the drivers’ side of the westbound lane. WYDOT came in and drilled down, discovering the air-filled gap.
