City explores options to solve issue on Eggleston, Frost streets

A growing sinkhole at the corner of Eggleston and Frost streets in Seligman has been visible for seven months and has grown to two feet in diameter.

According to Brian Nichols Seligman city clerk, the sinkhole started out as about an eight-inch hole that kept taking in dirt.

“It has gotten to about two feet now,” Nichols said. “It’s not just a bottomless hole, it just continuously sinks in. Over about a month, there was about a foot-and-a-half-drop in the hole.”

Nichols said it appeared about seven months ago, and the city hasn’t gotten an answer on what exactly it is.

“We have tried using cameras but the hole isn’t big enough to determine what’s going on there,” Nichols said. “It could be as simple a convert that has broken under the asphalt and created a bit of a void under it. It’s hard to say, we don’t know exactly what it is.”

Nichols said instead of closing down the intersection and ripping up the asphalt there, which would amount to a major repair, the city is trying to find some alternative options.

“MoDot wouldn’t be able to be of assistance because it is on the city streets,” Nichols said. “I have been in contact with DNR to see if there is some option as far as borrowing equipment like a ground penetrating radar, but there is some obstruction issues with asphalt.”

The city has the area roped off to make sure there isn’t any vehicle traffic, and at the moment they don’t see it being a large cavern under the road that is going to collapse.

“We are still just trying to figure out what is going on,” Nichols said. “It’s still in early stages, and we are trying to get a handle on it before it does potentially get worse. We are still exploring options.”

In other city business, the cemetery on Berry Avenue in Seligman is experiencing vehicle traffic getting too close to headstones.

“You get in there with a big truck and with the small intersections it can be hard to turn,” Nichols said. “People will start getting off the actual pathway.”

Nichols said the city wants to make sure there is no damage to the headstones, and there isn’t vehicle traffic over grave sites.

Instead of closing access to the roads, it was decided to rope off the corners of the pathway.

“We will drive at least three posts there and add some high-visibility chains between the posts,” Nichols said. “That way we don’t have individuals cutting into the corners and starting to get of onto grave sites.

“We want to solve the problem before it becomes a problem.”
