St. Louis (KMOV) - Area drivers will soon have more construction to navigate.
MoDOT broke ground on a project at I-270 and Dorsett Rd. Crews will build what they call a diverging diamond interchange.
This type of interchange allow free left turns for motorists, meaning vehicles will not cross opposing traffic.
The project is expected to begin after the new I-64/Highway 40 opens in mid to late December.
