The Missouri Department of Transportation is changing the way drivers will cross U.S. 63. Current crossovers at intersections will be removed and replaced with “J-turns.” The median on U.S. 63 will be narrowed, allowing MoDOT to shift U.S. 63’s southbound lanes into the existing median and build a new outer road in their place.

COLUMBIA—Two J-turns between Discovery Parkway Interchange and Bonne Femme Creek will open at 10 a.m. Wednesday.

This opening marks the completion of the first part of the Missouri Department of Transportation's U.S. 63 and H interchange project.

The J-turns are supposed to promote safer driving than the previous cross-over intersections. But, Charles Sullivan, the department of transportation's resident engineer, said drivers unfamiliar with the J-turns should watch the traffic in front of them and drive cautiously. 

The J-turns will also help with traffic flow.

"There's a learning curve on everything," Sullivan said. "But I believe this will be an easy curve (for drivers) to learn."

Supervising editor is Emilie Stigliani.

The illustrations of the current (past) crossovers on 63 are kind of misleading. They make it appear that there was barely enough room for 1 car to wait between traffic when in fact you could have 2-3 cars there waiting their turn.
