I-470 construction under way

Road Const OdDrivers need to find alternate routes during construction on a section of westbound I-470 near Kansas City, Mo., that collapsed July 17.

Repairs are scheduled to be finished no later than Sept. 15, according to the Missouri Department of Transportation.

A portion of the I-470 interchange to I-435 collapsed. A new 225-foot bridge extension will be added to the existing stable bridge at that location, MoDOT said.
