General Information

1. Project name: I-70 (I-435 to I-470) Corridor Improvements
2. City(ies), County(ies), State: Missouri Department of Transportation
3. Routes, interchanges and/or intersections: Interstate 70 from I-435 to I-470
4. Primary project mode: Highway/roadway 
5. Supplementary project mode(s): * Active Transportation * Bridge * Highway/Roadway )
This corridor is located in Kansas City and Independence. The existing system will be improved by constructing operational and safety improvements to the corridor. These improvements may include adding a lane on I-70 to accommodate the traffic, as well as TSMO strategies that include ramp metering and a potential for hard shoulder running for busses during peak hours, along with bridge and pavement improvements throughout the corridor to improve the system condition. This corridor is one of the most congested areas in the Kansas City area. The crash statistics along the corridor would be improved by reducing the number of crashes and improving the travel speed to be more reliable. 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. This project is part of the National Highway Freight Network Routes as a Primary Highway Freight System Route.
6. Project Purpose: * System expansion (added capacity) * System preservation, rehabilitation or replacement * System operations and management )

8. Total budget in 2019 dollars: $150000000
9. Project description: This section of I-70 has a completed First-Tier Environmental Impact Statement. The preferred alternatives for this study were to add general lanes for all traffic to use or the implementation of hard shoulder running for busses. The study went on to have five main purposes for this project: 1. Improve Safety along the corridor by reducing the crash rates and crash severity along I-70. 2. Reduce Congestion by removing key bottlenecks, reduce potential for ramp back-up onto the freeway, and improve multimodal travel times in coordination with plans put forward by local and regional agencies. 3. Restore And Maintain Existing Infrastructure by improving bridge and pavement conditions on I-70 and implement cost-effective investment alternatives. 4. Improve Accessibility by providing travel options for all residents, increase safe access across I-70 for non-motorized travel, and support local and regional land use plans. 5. Improve Good Movement by improving the efficiency of freight movement on I-70.
10. Scope: The key strategies that have been identified include: 1. Remove the key bottlenecks that occur at Lees Summit Road, Noland Road and I-435. 2. Add auxiliary lanes and/or extend acceleration and deceleration lanes to key locations to facilitate easier merge and diverge decisions for the traveling public. 3. Address all or most of the location with crash rates above statewide average by having targeted solutions that may include additional signing or high friction surface treatment. 4. Restore or Maintain the existing infrastructure. There will be one additional bridge (RR bridge, west of Noland Road) that will need to be replaced to accommodate additional capacity. The pavement condition will be addressed during this project, this section of I-70 has pavement from 1960s that should need rehabilitation before it is widened. 5. Improving the accessibility for non-motorized modes by created or improving the bicycle or pedestrian accommodations. This section of I-70 serves 124,481 vehicles per day and 46,708 trucks per day at the western limit of I-435 and 112,204 vehicles per day and 41,147 vehicles per day on the eastern limit of I-470. Also, this project is part of the National Highway Freight Network Routes as a Primary Highway Freight System Route.
11. Project schedule: The project is composed of only 1 phase. The estimated completion date for this project will be 2020-2030.
