The Missouri Department of Transportation is ending its five-year experiment with variable speed limit signs on Interstate 270.

Crews began removing the 70 digital signs from along the highway Wednesday. The work should be done in about two weeks.

MoDOT installed the signs in 2008 as a way to get traffic to slow down if there was congestion ahead. For the first three years, the speed limits they posted were enforceable, but MoDOT made them advisory-only in 2011.

Some rural, four-lane highways in Illinois will now have a 70 mph speed limit thanks to a bill signing by Illinois Governor Pat Quinn today.

Illinois will join 36 other states with speed limits of 70 mph or higher when the law takes effect on Jan. 1, 2014, Quinn's office says.

But, Illinois drivers in portions of St. Louis' Metro East might not be seeing the change - Quinn's office explains in their release:

Transportation officials are making changes to Interstate 270 and Interstate 255’s controversial variable speed limits.

MoDOT says a new study finds that they have helped traffic flow slightly since they were instituted in 2008, and accidents are down on the busy highway. So MoDOT engineer Tom Blair says they’ll make the variable speed limits simply "advisory" by this summer.
