A stretch of road in Miamisburg and Miami Twp. reopened last week following significant erosion forced officials to close it in 2018.

Lower Miamisburg Road has been closed between South Union Road and Dee Avenue since spring of last year. The road was completed on the June 28, ahead of schedule.

“Construction went well and I think that has to do with the fact that it was a cooperative effort between the City of Miamisburg, the county, and the county engineers,” said Miamisburg City Engineer Bob Stanley.

One of the main purposes behind the emergency renovation is preventing erosion and landslides, as the road runs along a hillside with a stream below.

“It’s a fairly significant failure as you can see from the drop in elevation,” Stanley said after the road was damaged. “It’s mainly the water, the saturation, the heavy rain.”

Hillside terrain near the edge of the road as well as heavy spring rains last year contributed to the asphalt buckling, according to Stanley.

The first phase of the project included installing three sections of wall, including 70, 30-inch diameter concrete reinforced drill piers.

Phase II of the project included fixing the road itself, Stanley said. This work involved reconstructing both lanes, and storm drainage work on Lower Miamisburg’s north side.

Stanley says that both phases of construction went smoothly and as planned.

“Both phases went very well, we didn’t experience any hiccups,” Stanley said. “The road opened ahead of the date originally planned.”

Miamisburg used a state loan to help pay for the $1.1 million repair work. Most of the funding was spent on a wall to prevent erosion that caused deterioration beneath the asphalt, leading to increased landslide conditions.

“A huge portion of (the cost) is in the wall,” Stanley said. “The rest of it’s in the drainage and the road work.”

Although the newly renovated section is low volume in terms of traffic, Stanley says the response from the community has been positive.

“We’re very pleased it’s open and you can just tell from the feedback from the residents in the area.”
