General Information

G8.1 Project title: US 56 & I-35 Interchange Improvements
G8.2 Project description: The existing interchange is a large rural diamond with a single loop ramp. The design will address improvements needed to accommodate near-term development and identify the future interchange configuration needed to handle full development of the US-56/175th Street corridor. The project will be designed to accommodate all vehicle types and provide access across I-35 for pedestrians and bicyclists. With the addition of KCATA transit routes from downtown KC to Gardner and Edgerton, the interchange will assist in improving local and regional mobility, increase long-term economic development and attract and retain residents and businesses by connecting people to regional jobs.

G1. Project Type: Road & Bridge - Roadway Capacity
G2. Funding Stream: STP
G3. TIP Number:
G4. State: Kansas
G5. Project county: 1. Johnson
G6. Project municipality: 1. Gardner 2. Johnson County
G7. Multiple agencies / jurisdictions? No
G8.4 Purpose and need: Much of the area around the interchange is currently undeveloped. Olathe has already had significant development occur to the east. Olathe and Gardner will continue to have new development that will significantly increase traffic through the interchange. Traffic studies for potential development indicate that signals and additional turn lanes at the interchange will be needed soon. To avoid spending money on interim improvements it is important that the ultimate interchange configuration be determined. This will also accommodate the large amount of freight trucks coming through Gardner on their way to the intermodal facility in Edgerton.

G10. Functional Classification: Principal Arterial
G11. In Transportation Outlook 2040? Yes   Decade:   2010
G12. Muli-Agency Plan? Yes
The City of Olathe has great interest in improvements to the interchange, as it will benefit them as well. They have had significant development recently east of the interchange and anticipate the development to continue. Their TMP shows it as a future 4-lane with turn lanes.
G13. Included in a CIP? Yes
This project is included in the Citys Transportation Master Plan and on the current draft CIP.
G14. Planning stage: Conceptual Plan
G15. Reviewed by state DOT? No
G16. Right-of-Way acquisition: All acquired or none needed
G17. ROW by local public agency process manual? Yes
G18. Other unique local goals and objectives? No
G19. Transportation Disadvantaged Population: There are 141 households in Gardner with no motor vehicle and the highest percentage of veterans living in Johnson County, reside in Gardner. These vulnerable populations require safe and accessible routes to schools, grocery stores, public transportation and other services. The project will provide improved access across I-35 to future commercial development thru the addition of sidewalks where there currently are none. This will positively affect all of the disadvantaged populations.
G20. Relevant Public Engagement: The Citys Business and Economic Development Dept held public meetings to discuss future development possibilities for the area east of this interchange. The discussions included potential improvements to the local roadway network and the interchange. Additional public engagement and market research occurred through the recently completed Main Street Corridor PSP study. The charrette provided guidance for the vision of the corridor, including the area around the I-35 interchange.
G21. Planned Public Engagement: Key stakeholders will be identified and met with on an individual basis to gather input. A public meeting will be held for all citizens to attend and provide comments. The City of Gardner has standing committees of citizens that are regularly engaged in the public process. These advisory committees include: ADA; Economic Development; Parks and Recreation; Streets, Sidewalks and Stormwater; and Citizens Police Advisory Committees. Public engagement has been an integral part of all recent planning projects and many Council decisions. The City is fortunate to have active participants in five standing citizen advisory committees. There is also a full-time Communications/Public Information Officer to respond to citizen inquiries & provide community updates through newsletters & social media postings. In addition to financial support, the City demonstrates its commitment by utilizing staff expertise as needed to maintain the project budget.
G22. Sustainable Places Criteria: ---------------- Complete Street Design--------------- ------------Integrated Trail System--- ---------------- ---------------- ------
G22.1. Describe CSP relationship: This project will help connect people to places by creating a corridor that provides transportation choices, accommodates walking, biking, and public transportation as well as the automobile. This will create better access to more destinations using different modes of transportation. It will also improve public health through the encouragement of more walking and biking and a future connection to parks and trail systems.
G23. Implements Sustainable Places Initiatives? Yes
The City recently completed a PSP project for the Main Street (175th/US-56) corridor. The plan did not make specific recommendations for the I-35 interchange but the changes being considered are consistent with the recommendations for Main Street near the interchange.
G24. Serves Regional Activity Center? No
G25. Environmental justice tracts? No
G26. Reduces greenhouse gas emissions? Yes
During peaks traffic backs up onto southbound I-35. The project will significantly reduce delays by more efficiently moving traffic with a combination of turn lanes and signals. By improving traffic flow, it decreases idle times. Providing walkability and biking options will reduce per capita vehicle miles traveled and improve air quality. By improving traffic flow, it decreases idle times. Providing walkability and biking options will reduce per capita vehicle miles traveled and improve air quality.
G27. Natural Resource information: Best management practices for erosion control will be implemented during construction to prevent sediment from being carried offsite and into downstream communities and parks. Practices like soil conservation, tree planting and native landscaping will be utilized.
G28. Community Links at Watershaed Scale: Site development plans will incorporate rather than replace the natural landscape, especially trees.
G29. Explain local land use or comprehensive plans: The Citys Comprehensive Plan specifically identifies this interchange as needing improvements to meet future traffic demands.
