Summary of I-35/I-670/US-71 Downtown Loop Improvements

MoDOT

Project Number:	1353
Organization:	MoDOT
Project Name:	I-35/I-670/US-71 Downtown Loop Improvements
City(ies), County(ies), State:	Missouri Department of Transportation
Routes, interchanges and/or intersections:	I-35, I-670 and US-71
Primary Project Mode:	Highway/roadway
Supplementary Project Mode(s):	* Active Transportation * Bridge * Highway/Roadway ) These interchanges are located in Kansas City, Missouri. 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.
Project Purpose:	* System expansion (added capacity) * System preservation, rehabilitation or replacement * System operations and management )
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-35, I-670 and US-71 and implement cost-effective investment alternatives. 4. Improve Goods Movement by improving the efficiency of freight movement on the interstate.
Scope:	Since this project is forecasted for 2040-2050, 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. This project 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, ramp and interchange reconfigurations, or relocate a bridge to provide greater access for the communities. On I-670, the construction of two through lanes in the EB direction would provide better lane balance and traffic flow through the corridor. 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.

These improvements are well needed! However, the local community wants the Northloop (i70) removed and it is of great importance that these improvements support that goal.

Enter comment hereWe need to strong consider REDUCTION and not just restore/maintain. I strongly support the reduction of highway capacity in favor of building out a more robust complete streets and public transit network in their place). If a reconstruction of this highway must be done, I would suggest i35 is relocated to the west away from its current alignment next to the Crossroads. These are all views that I often hear echoed by others in the area.
