Summary of I-470 Capacity Project US 50 to 39th Street


Project Number: 1497
Organization: MoDOT
Project Name: I-470 Capacity Project US 50 to 39th Street
City(ies), County(ies), State: This project is within Jackson County, Missouri, and touches the cities of Lees Summit and Independence.
Routes, interchanges and/or intersections: This project will add capacity to I-470 and make operational improvements to I-470. The project includes the interchange with US 50, Douglas Road, Colbern Road, MO 291, Woods Chapel Road, Strother Road, Lakewood Boulevard, US 40 Highway, I-70 and 39th Street.
Primary Project Mode: Highway/roadway 
Supplementary Project Mode(s): * Freight * Highway/Roadway )
This project will add capacity from US 50 in Lees Summit to 39th Street in Independence. This corridor carries between 60,000 and 80,000 vehicle trips per day, including about 4,700 truck trips. This project will help alleviate congestion points in the corridor, improving vehicular flow and safety for travelers in single occupancy vehicles, carpools or vanpools. I-470 is also a Tier 1 roadway in the Statewide Freight Plan and 12 to 20.5 million tons of freight move along I-470 each year. This improvement will help freight move along this portion of the interstate corridor in a more efficient manner. There is some express transit in this project corridor. However, additional capacity would support future transit services. Non-motorized modes are incompatible with high speed low access interstate travel, and not encouraged in the right-of-way.
Project Purpose: * System expansion (added capacity) * System preservation, rehabilitation or replacement * System operations and management )
Project Description: This project is located along I-470 between two large suburban communities (Lee’s Summit and Independence). This project will add a lane of thru traffic in each direction to improve traffic flow and improve congestion. As Lee’s Summit, Independence, and communities to the east continue to grow, I-470 provides a connection to commercial and industrial areas along I-470, as well as, employment concentrations in the south Kansas City and Johnson County, Kansas. While the congestion and crash rates in this corridor are not the highest in the district, as eastern Jackson County continues to develop, traffic volumes and congestion are projected to continue to increase in the future. I-470 is a Tier 1 Freight corridor in the Statewide Freight Plan. The amount of truck traffic is expected to increase from 4,700. The addition of capacity should improve Goods Movement by improving the efficiency of freight movement and access to the local road network. This project may include other improvements, as well. If there are bridges that need to be rehabilitated, those may also be added to the project. Many of the interchanges within the corridor may need operational and geometric upgrades.
Scope: I-470 is a four-lane interstate that is grade separated in the project corridor. Traffic volumes range from an average of 60,000 to 80,000 vehicle trips per day with about 4,700 trucks per day. I-470 is a Tier 1 freight route in the statewide freight plan. The Kansas City region is one of the busiest freight hubs in the nation, and freight volumes are projected to continue to increase in the future. This project is expected to be programmed between 2030 and 2040. Since this project is forecasted for 2030-2040, the complete range of solutions for this project are not completely defined. Additional capacity is needed, but other options may include peak hour bus-on-shoulder or auxiliary lanes to accommodate higher volumes of large trucks as the transportation system evolves over the next decade. This project includes several bridges that may need replacement or serious rehabilitation treatments. It makes sense to include the improvements to traffic flow and bridges are as the new lane is added to the corridor. Some bridges may need to be lengthened to accommodate the additional lanes, and some might need to relocated to provide greater access for the communities.

Our region doesnt need more highway lanes. Already ourregion has more than twice as many highway miles per capita as the next highway clogged city. Environmentally we cannot seriously consider putting driving needs at the forefront of our problems. Focus improvements on regional transit and concentrated growth patterns.
