The Project will address the primary areas of concern identified in the Concept Study, and will deliver the highest value improvements possible within the T-WORKS budget. The following will be included in the planning:
- Right of way acquisition
- Utility relocation
- Undermined remediation
Preliminary Concept Map:
Yes, this work is currently underway with preliminary engineering.
Will a Conditional Letter of Map Revision (CLOMR) or a Section 404 Permit be required on this Project?
Yes, because of impacts to existing detention areas and streams. These agency approvals are being coordinated as part of preliminary engineering.
Yes, since this is a Federal Aid Project.
KDOT will make available on the Project website utility relocation plans after the design for the relocation plan has been completed and the utility has approved the relocation plan. KDOT will include in the RFP to D-B proposers preliminary and final utility relocation plans, whichever KDOT has at the time the draft RFP is distributed to D-B proposers. KDOT will update utility relocation information throughout the RFP process as updates become available.
Improvements currently under construction are the I-435 & U.S. 69 Red Project. The Gateway Yellow Project improvements added two auxiliary lanes in the northbound and southbound directions along I-35 between 119th Street and I-435. These improvements were substantially complete in December 2012. The additional surfacing and pavement marking work was completed in the Spring 2013. The I-435 & US-69 Red Project improvements will add an auxiliary lane in each direction between I-35 and Quiviria Road. These improvements are scheduled to be complete by November 2013.
Construction is anticipated to start by Summer 2014.
It will be necessary to close some interchanges during construction. However, it is unlikely that two adjacent interchanges will be closed at the same time.
Are there any plans to improve College Boulevard to help with increased traffic during construction?
Yes. KDOT and the cities of Lenexa and Olathe have agreed to include improvements to College Boulevard between Renner Boulevard and Ridgeview Road as part of the Phase 2 Project.
Yes. KDOT and the cities of Olathe and Lenexa have agreed to include this project as part of the Phase 2 Project.
KDOT has been planning for these projects to be closely coordinated for several years. For example, the Red Project noise walls and berms were designed to accommodate the Purple Project improvements.
There are existing undermined areas near K-10 and Renner Boulevard and the advance mine remediation project will stabilize voids with rock material beneath the proposed roadway improvements. This work will occur in 2013, in advance of selecting a design-build team.
KDOT has the right to reject any proposals that are deemed unacceptable.
Yes, a stipend in the amount of $500,000 will be paid to each of the unsuccessful shortlisted proposers.
The selection process will follow a two-step procurement process including a Request for Qualifications (RFQ) and a Request for Proposals (RFP). Additional detail on the procurement schedule can be found at the following link:
KDOT shortlisted three of the most highly qualified teams.
No previous teaming is required.
Tolling is not a part of this Project.
In general, KDOT design criteria will be used on the Project.
Will the aesthetics on this job be required to match the aesthetic theme to the east of the Project?
Aesthetic requirements have not yet been determined.
KDOT and the City of Lenexa have agreed to include this project as part of the Phase 2 Project.
Yes, there will be a Draft RFP in May 2013. Industry reviews will take place in June 2013. A final RFP will be issued in June 28, 2013 and the Final RFP with Addenda will be released in October 2013.
Yes, 10% of the RFP amount. There is also a trainee goal of 10,000 hours.
Appropriate information from the preliminary design will be made available in early 2013.
Broad guidance will be provided.
KDOT will provide designs for both rigid and flexible pavement sections. The Design-Builder may use those sections or propose Alternative Technical Concepts (ATCs) for pavement sections.
1.27M square yards for the entire Project. This includes the yet-to-be-determined Blue Phase.
KDOT recognized the need to study this area based on traffic and congestion in the area as well as the age of the pavement. The I-435/I-35/K-10 Interchange area was also identified as a priority need by the local communities to improve safety and mobility through this area.
The study area was defined as I-435 from Quiviria Road to 87th Street, I-35 from 95th Street to 119th Street and K-10 from Woodland to I-435. A half-mile area adjacent to the highway on either side will be evaluated for potential impacts.
The study was completed in about 30 months and had three phases: Phase 1 – evaluate existing and future conditions; Phase 2 – determine feasible alternatives and select a preferred improvement concept, and Phase 3 – develop a phasing plan which prioritizes improvements over time.Download a Study Schedule
Yes. KDOT is committed to engaging the public to learn what types of transportation investments are important. For the Johnson County Gateway project there were two public meetings, electronic outreach including a website with a blog, online surveys, focus groups, community presentations, media relations, public official’s briefings, advisory group meetings, and two issues workshops.
The Concept Study developed recommendations for future improvements to the interchange. Phase 1 (the Yellow Project) will be completed in late 2012. Phase 2 is scheduled to begin in 2014. The completion of Phase 3 is dependent on funding.
Since the interchange area is multi-jurisdictional, KDOT engaged the cities of Olathe, Lenexa and Overland Park, Johnson County, the Mid-America Regional Council and the Federal Highway Administration as Study partners.
The Johnson County Gateway: I-435/I-35/K-10 Interchange is one of the most congested interchanges in the state. Accident rates are above the statewide average and the existing pavement needs to be replaced. Continued economic development in the region depends on a safe and efficient Gateway Interchange. Improvements will reduce congestion and improve safety in the area.
The proposed improvements are designed to enhance safety and reduce congestion through the I-435/I-35/K-10 interchange area. By adding new lanes and using collector-distributor roads to reduce the weaving of ramp traffic with mainline traffic, the driver experience through the area will be safer and more efficient.
The study recommendations were completed in 2010. The study identified ways to improve traffic flow. Phase 1 (the Yellow Project) began in 2012 and added auxiliary lanes from I-35 from 119th Street to I-435 in both directions. Phase 2, scheduled to begin in 2014, will address the majority of the existing issues in the area. The completion of Phase 3 will be dependent on funding.
Total improvement costs are estimated to be $600 million (2016 dollars). Projects will have to be phased in over time. Pending future programming decisions, design, right of way, and utility relocations, it could take 20 years to complete the entire interchange improvements.
All of the improvement options will enhance EMS access into and through the interchange.
Even with multiple transit strategies employed, traffic models suggest it is unlikely we will be able to shift enough people from single-occupancy cars to buses to solve the congestion problem. Thus, improvements to existing routes will still be required. No one strategy by itself will solve the congestion problems we anticipate. A range of strategies is needed. This will likely include some combination of additional capacity (e.g., HOT lanes, managed lanes), mode shift (e.g., carpools, transit), travel demand management (e.g., staggering work hours, ramp metering, coordinating land use planning with transportation on a regional scale), and other appropriate traffic management solutions. Johnson County Transit has implemented Bus on Shoulder use during peak travel on I-35 to increase transit opportunities along the I-35 corridor.
This interchange is one of the busiest in the state of Kansas and very important to the economic vitality of the region. It is a huge priority for Kansas and the local communities. This interchange system is a critical link for the metropolitan area and the state, as several important trade routes pass through this interchange. If improvements are not made soon, traffic delays and unreliable travel will hurt the economic vitality of the surrounding communities. Given the interchange’s importance to the region and the state, this Study was one of two Preliminary Engineering (PE) Only Projects in Johnson County and one of three in the KC Metro Area.
It is one of the most important needs in the region and the state. It’s important to plan ahead for any transportation improvement since it takes years for actual construction to occur.
This may increase the time it takes for trucks to get from my business to the highway. How will I be compensated?
There will not be any compensation for any increase in travel time to your business. Planned improvements will reduce congestion and travel times, and improve safety and reliability, which will help businesses in the area.
The first phase, the Yellow Project began construction in 2012. The Yellow Project will add auxiliary lanes to I-35 from 119th Street to I-435 in both directions. This will relieve some of the more significant congestion areas which people experience today.
The local communities were engaged as partners in this Study. They had the opportunity to provide input into all aspects of the Study process. The Study partners asked rigorous questions and requested additional information (e.g. traffic analysis of specific options) to address their comfort level with the proposed concepts.
