State DOT crews installing barriers in I-75, I-16 medians

Georgia Department of Transportation crews are installing cable barriers in the medians of Interstate 75 and Interstate 16 in and around Macon.

The project eventually will cover about 14 miles of the interstates, starting in the area of Walnut Creek beneath I-16 and continuing to the Ocmulgee River, then starting again just north of Arkwright Road and continuing into Monroe County along I-75.

A trench is dug, concrete is laid down, metal posts are sunk into the concrete and strung with metal cable.

The idea, DOT spokeswoman Kimberly Larson said, is to prevent head-on collisions by keeping out-of-control cars from crossing the median.

Cabl barriers are used because their maintenance costs are significantly less than those of traditional guardrails, according to information from the American Association of State Highway and Transportation Officials.

The total cost of the project, which should be complete by the end of October, is about $2.2 million, Larson said. Nationwide Construction Group, of Michigan, is handling the project.
