The Missouri Dept. of Transportation tentatively has set September 15 as the target date to restore access between I-470 and I-435 in southern Kansas City, following an existing fill-supported ramp collapse on July 17.
Pyramid Contractors, Olathe, Kan., was awarded the contract to build a 225-ft-long, four-lane replacement structure currently being designed by HNTB, MoDOT’s engineering consultant. Expected to cost about $4.46 million, the precast structure will be built atop two bents with drilled shaft foundations socketed to bedrock.
