This interchange is located in Lees Summit, Missouri which is one of the largest suburbs of metropolitan Kansas City. The existing system will be improved by creating flyover ramps to provide greater mobility, reliability and a safer system by reducing the number of decision points and conflict points. While providing this greater level of service to the public, the freight and transit communities will also benefit from the reduced travel time, greater reliability and safety improvements. There are currently two express routes, I-435 Express, that utilize this interchange. The 470 and US 50 interchange serves 153089 vehicles per day and 49088 trucks per day. These are freight corridors and are located within freight zones according to the Regional Freight Outlook from 2009.

10. Scope: The project purpose is to improve the operational and safety features of this interchange. The project will consist of new flyover ramps, ramp modifications, signing, bridge and roadway improvements. The proposed scope would include constructing two flyover ramps, one from WB 50 to WB 470 and the other from WB 470 to EB 50. The two cloverleaf ramps on the north side of th interchange would be removed and replaced with the two previously mentioned flyover ramps. This would require additional roadway and bridge to be constructed, but with the age of the system there will be a need for rehabilitation of the existing facilities when this interchange is redesigned.
