MoDOT



Project Number: 1236
Organization: MoDOT
Project Name: I-70 and I-470 Interchange Improvement
City(ies), County(ies), State: Missouri Department of Transportation
Routes, interchanges and/or intersections: Interstate 70 and Interstate 470
Primary Project Mode: Bridge 
Supplementary Project Mode(s): * Highway/Roadway )
This interchange is located in Independence, Missouri which is one of the largest suburbs of metropolitan Kansas City. The existing system may be improved by constructing a turbine interchange or collector-distributor type system 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 I-70 and I-470 interchange serves 191,595 vehicles per day and 64,639 trucks per day. This project is part of the National Highway Freight Network Routes as a Primary Highway Freight System Route. This project currently has two Express Transit routes, Lees Summit Express and Blue Springs Express.
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 may consist of constructing a new turbine interchange with ramp modifications, signing, bridge and roadway improvements or some sort of collector-distributor partial turbine. The preferred alternative has not been decided. This interchange is located in Independence, Missouri which is one of the largest suburbs of metropolitan Kansas City. The existing system will be improved by creating direct connections without cloverleaf 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 I-470 and I-70 interchange serves 191,595 vehicles per day and 64,639 trucks/buses per day. This project is part of the National Highway Freight Network Routes as a Primary Highway Freight System Route.
Scope: The project purpose is to improve the operational and safety features of this interchange. At this stage, the project has several alternatives for ramp configurations. It may consist of constructing a new turbine interchange, or other direct connection points that do not involve cloverleaf ramps, but would include ramp modifications, signing, bridge and roadway improvements. The proposed alternatives have been attached to this application. With all the alternatives that have been discussed, at least two cloverleaf ramps within the interchange would be removed. 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. The existing system will be improved by creating smoother connections 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 I-470 and I-70 interchange serves 191,595 vehicles per day and 64,639 trucks/buses per day. This project is part of the National Highway Freight Network Routes as a Primary Highway Freight System Route.
