Roundabout construction briefly closing rest areas

Two Interstate 20 rest areas in Columbia County will be closed for a few days next week as preparations begin for construction of a roundabout at Pumpkin Center.

The rest areas on I-20 near the McDuffie County line will be closed Tuesday through Thursday to allow crews to relocate a sewer main associated with the planned traffic circle at the intersection of Appling-Harlem Road and Wrightsboro Road, according to Harlem City Manager Jason Rizner.

A force sewer main owned by the city of Harlem serves the rest areas and is in the Georgia Department of Transportation right-of-way. It will be relocated during the closure, according to Rizner. A city-owned water line was relocated from the right-of-way last week.

The project includes replacing the four-way stop at Pumpkin Center with a traffic circle.

The roundabout will extend 0.36 miles, according to the DOT. It will include two lanes at a width of 11 to 15 feet, sidewalks, curb and gutter, and splitter islands on each of the four approaches. It also will have a truck apron and a central island, and will be lighted.

Wow! That roundabout sounds like a mamma jamma. It will be a showpiece for traffic engineers from all around the state to come and see.

By the way, what is a "truck apron?"

Also, wouldn't it be nice if a Pumpkin Center garden club would make some attrative plantings and maintain the horticulture in the central island?

Sweet son

The roundabout will probably be great for traffic flow but

all of the landscape in the interior and on the outer rights of way will fall on CC for maintenance. Sure hope Little Lamb's suggestion is doable. The current roundabout in Evans and the one near Carmax are pretty ragged!


Modern roundabouts

clear typo. no traffic circle, let alone modern roundabout, is 1900 ft in diameter (.36 miles).
The FHWA has a video about modern roundabouts that is mostly accurate (http://www.youtube.com/watch?v=uhHzly_6lWM ).
The truck apron is the flat area around the circular island. It's for long vehicles to start or finish a turn on - rear wheel tracking usually.
