General Information

1. Project name: I-29 and I-35 Corridor Improvements
2. City(ies), County(ies), State: Missouri Department of Transportation
3. Routes, interchanges and/or intersections: Interstate 29 and Interstate 35
4. Primary project mode: Highway/roadway 
5. Supplementary project mode(s): * Active Transportation * Bridge * Highway/Roadway )
This interchange is located in Kansas City, Riverside, Northmoor, and Gladstone. The existing system may be improved by adding auxiliary lanes, improving the acceleration and deceleration lanes, and improving the traffic flow along the corridor. There are signficiant delays along this corridor in the AM and PM Peak Hour travel periods. This corridor is one of the highest traveled and congested areas in the Kansas City area. The safety 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. Also, 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 )
7. Project sponsor: Griffin Smith
8. Total budget in 2019 dollars: $120000000
9. Project description: There are several purposes for this project: 1. Improve Safety along the corridor by reducing the crash rates and crash severity. 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-29 and I-35 and implement cost-effective investment alternatives. 4. Improve Accessibility by providing travel options for all residents, increase safe access across the interstate for non-motorized travel, and support local and regional land use plans. 5. Improve Goods Movement by improving the efficiency of freight movement on the interstate.
10. Scope: Since this project is forecasted for 2030-2040, the scope of the solutions for this project are less defined than others, but it is clear that the system is at capacity during the peak travel times, so looking at options that may include peak hour bus-on-shoulder or adding auxiliary lanes to provide a smoother merge time for the motorists can provide those improvements. This project also has several bridges that are at the point of needing replacement or serious rehabilitation treatments that it makes sense to make the improvements to traffic flow when the bridges are being rebuilt. This would be the time to lengthen the bridges to provide additional capacity or relocate a bridge to provide greater access for the communities. This section of I-29 and I-35 serves on average 84,898 vehicles per day and 27,729 trucks per day. 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.

I-29/I-35 entrance ramps has been giving drivers stressful moments. The lack of acceleration lanes increases the chance of a rear-end or a side-swipe collision. This corridor desperately needs traffic flow improvements to reduce collisions or near-collisions.
