Q: Why is this project necessary?

A: A study completed in 2007 identified safety and operational problems with the I-235 interchanges at Kellogg Avenue and Central Avenue.   Geometric improvements to these interchanges to safely and efficiently accommodate current and projected traffic volumes are the primary reason for the project.

Q: What did the previous study conclude?

A: The study identified a four-level directional interchange for I-235 and Kellogg Avenue and a tight diamond interchange for I-235 and Central Avenue connected with auxiliary lanes along I-235. Additionally, the study identified braided ramps between the I-235 interchange and the West Street interchange on Kellogg Avenue. The study also proposed interim improvements to Central Avenue to ease congestion in the short term. These interim improvements to Central Avenue have already been built. For more information, the final study report can be found on this website.

Q: What improvements are being proposed?

A: The proposed project will include a four-level directional interchange at I-235 and Kellogg Avenue, a tight diamond interchange at I-235 and Central Avenue, and modifications to the single-point urban interchange at Kellogg Avenue and West Street. Interstate 235 will be reconstructed from south of Kellogg Avenue to north of Central Avenue. The reconstructed I-235 will be raised to provide better clearance at the bridges over Kellogg Avenue, Maple Street, and Central Avenue. An auxiliary lane for both northbound and southbound I-235 will be provided between the Kellogg Avenue and Central Avenue interchanges. Kellogg Avenue will be reconstructed to provide wider shoulders and lanes from west of the Big Ditch to the Meridian/Southwest Boulevard interchange. A braided ramp system will be constructed between I-235 and West Street. West Street will be reconstructed lower under Kellogg Avenue to provide more clearance.  Central Avenue will be reconstructed from Boyd Street to Hoover Road.

Q: How can the public provide input?

A: There are several ways the public can provide input and find information. Information about the project can be found on this web site. You can give feedback on this web site via email. Input can also be provided by attending public meetings which will be announced through various media.

Q: When will construction take place?

A: Due to the size of the project it will likely be constructed in phases over many years.  A first project, the “Red” Project, has been identified and is funded as part of T-WORKS. The Red Project includes a partial reconstruction of the I-235 and Kellogg Avenue interchange and will greatly improve the safety and operational issues currently experienced at this location. Future construction phases will be planned when funding sources are known.

Q: How will traffic be impacted during construction?

A: Traffic on I-235 and Kellogg Avenue will be maintained throughout construction although traffic delays will likely be worse during this time. Narrow lanes with barriers on either side will be necessary at some locations to provide safety for construction workers. Four lanes on I-235 will be provided throughout construction with some short-term lane closures possible. Kellogg Avenue may experience lane closures for periods of time. The major movements at the I-235/Kellogg Ave interchange will be maintained if possible. Access across the Big Ditch will also be maintained.

Q: What is the cost of the project?

A: The preliminary estimated cost of constructing all of the improvements in today’s dollars is $299 million. The first project planned to be built, the Red Project, is estimated to have a construction cost of $116 million.

Q: Will any businesses or residences be taken as a result of this project?

A: Areas of potential right-of-way have been identified along the entire project that include some businesses and residences. However KDOT is primarily focusing on purchasing right-of-way for the funded Red project. The process of purchasing right-of-way for the Red project will begin in 2013 and will continue through 2015.

Q: Will there be access provided at Maple Street?

A: No. KDOT considered a new interchange on I-235 at Maple in 1999 during a previous study. At that time, KDOT concluded that there were serious safety and operational problems with adding a new interchange at this location due to the proximity of the Kellogg Avenue interchange. Since 1999, safety and operational conditions have worsened and the proposed improvements to the Kellogg Avenue interchange will push even closer to Maple Street.

Q: Will noise walls be constructed as part of this project?

A: KDOT has completed a highway traffic noise study along the entire project that used a noise evaluation based on the KDOT Highway Traffic Noise Policy. This study concluded that noise walls did not meet reasonable criteria and noise walls will not be constructed along this project.

Q: Are additional Wichita-Valley Center Floodway crossings planned?

A: While it will be necessary to construct new bridges for Kellogg Avenue and several ramps over the Wichita-Valley Center Floodway, additional crossings are not part of this project.
