Roundabouts


How to drive a roundabout

In 2001, Chattanooga Traffic Engineering introduced to Chattanooga residents a new concept in intersection traffic control with the building of a roundabout at the intersection of Westside Drive at 29th Street on the west end of Bachman Tunnel on the side of Missionary Ridge. The modern roundabout design is a relatively new design concept in the U.S., with the first modern roundabout being built in 1990 in Nevada. Since then many other states have adopted this design strategy.

The intersection of Highway 153 access ramps, Lake Resort, and Access Road has been redesigned and is Chattanooga's first two lane roundabout. The following files will help you familiarise yourself with how to navigate this intersection.
