General Information

1. Project name: Kansas River Bridge at De Soto, KS
2. City(ies), County(ies), State: Johnson County, Leavenworth County, City of De Soto
3. Routes, interchanges and/or intersections: From the intersection of Wyandotte and 82nd Streets in De Soto, north across the BNSF Railway and the Kansas River to touchdown on Leavenworth County Route 2 (166th St.)
4. Primary project mode: Bridge 
5. Supplementary project mode(s): * Active Transportation )
The replacement of the 55-year old existing bridge (load posted, narrow, fracture and scour critical) will provide for unrestricted vehicular movement across the Kansas River, a significant natural barrier in the metropolitan area. Currently, this structure is the only access across the Kansas River between Eudora and K-7 highway. Loss of the structure, if not replaced at the upcoming end of its service life, would result in long detours and would significantly increase the vehicle miles traveled and time delays for area motorists. In addition, pedestrian and bicycle modes will be included with the structure design to provide a vital link for active transportation modes between Johnson and Leavenworth Counties.
6. Project Purpose: * System preservation, rehabilitation or replacement * Other (Add bike/pedestrian)
7. Project sponsor: Geoffrey Vohs
8. Total budget in 2019 dollars: $14000000
9. Project description: The purpose of the project is to replace an aging structure that provides one of the few crossings of the Kansas River in the western portion of the metropolitan area; a link that will be vital as development in the western metropolitan region continues. The primary users will be motorists. Pedestrian and bicyclists will also benefit with the addition of cross-sectional elements that are conducive to active transportation modes. Although this is not a freight route, the elimination of the load posting would benefit the movement of local freight.
10. Scope: The overall project would be approximately one-half mile long. A structure with 2-12 foot lanes, 6 foot shoulders and a separate non-motorized path on one side is envisioned. The shared use path would provide safe crossing for less experienced cyclists/pedestrians by separating them from traffic. Unlike many other Kansas River crossings, which are located on high volume state highways, this project is on a city street/rural secondary road. This non-highway type of environment would be more palatable to the inexperienced cyclist. It is likely that experienced cyclists, regardless of the presence of the shared path, would opt to use roadway shoulder in lieu of the shared path. Metal rails satisfactory for cyclist protection would be placed above concrete vehicle barriers to provide a safe railing for cyclists utilizing the shoulder. In order to avoid a 2-year shutdown of the route, it is probable that an offset alignment would be used to allow the existing structure to carry traffic during construction. The existing structure would be removed at the end of the project.
