Roundabout coming to County Road 73

Jefferson County Highways and Transportation will soon begin a $2 million project to widen a portion of County Road 73 in Marshdale, which includes adding a roundabout at the intersection with North Turkey Creek Road.

The road improvements address safety concerns cited in traffic studies in recent years, according Gary Campbell, a construction manager with the department who will oversee the project.

Other improvements will include the addition of a center turn lane that will be built from the roundabout to the nearby Evergreen Professional Center.

The project, a half-mile in length, will affect traffic from North Turkey Creek to Thimbleberry Lane.

“There are so many businesses and driveways to access along that stretch ee we are really trying to improve the safety,” Campbell said. “Traffic studies show a lot of rear-end collisions there. That is the reason for the center turn lane — to get the traffic out of the through lane.”

The focal point of the project is the roundabout that Campbell describes as a three-legged design.

The county was able to negotiate the purchase of private land in that area, and no condemnations were necessary, he said.

It will be one of about a half-dozen roundabouts in the county, by his estimate.

Highways and Transportation expects the entire construction project to take about six months, from March through September of this year.

It will also include building 6-foot-wide shoulders on both sides of County Road 73 in that vicinity and completing limited drainage improvements.

American Civil Constructors won the bid for the project, Campbell said. That’s the same contractor that completed the road improvements to County Road 73 about two years ago near the Flying J Ranch, and the company finished that project “way ahead of schedule,” he said.

“I am keeping my fingers crossed that that will happen here too,” Campbell said.

A contract with the builder stipulates that entryways to businesses remain open throughout construction, he said.

But Campbell said commuters on County Road 73 should expect some delays and lane closures.

“It’s a construction zone — it’s going to be inconvenient — but the road will be open.”
