MoDOT

Project Number:	1203
Organization:	MoDOT
Project Name:	I-470/US 50 Interchange Improvement
City(ies), County(ies), State:	Missouri Department of Transportation
Routes, interchanges and/or intersections:	Interstate 470 and U.S. 50
Primary Project Mode:	Bridge
Supplementary Project Mode(s):	* Highway/Roadway ) 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.
Project Purpose:	* System expansion (added capacity) * System operations and management )
Project Description:	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. 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. The 470 and US 50 interchange serves 153,089 vehicles per day and 49,088 trucks/buses per day. These are freight corridors and are located within freight zones according to the Regional Freight Outlook from 2009.
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.

Next to the addition of traffic lanes on I-470 between 39th St. and 50 Hwy, this is one of the most needed infrastructure improvements in the KC metro area and one that needs to be addressed sooner than later. As a first responder who responds to traffic accidents on this stretch of interstate and at the 470/50 interchange on a regular basis, this is something that should have been addressed years ago as it continues to cause accidents and slow traffic on almost a daily basis. While MoDOT is asking for these funds for improvements, THEY should have also planned for these improvements in their short range goals and funding many years ago. There is absolutely no reason that the eastern portion of the state continues to receive highway funding for additional lanes on I-270 while the KC metro gets passed over.
