Phase 2 of the Johnson County Gateway Project is scheduled to be complete by December 31, 2016.
Construction will begin in mid to late May 2014. You will see some activity along the entire project route (utility marking, surveying, etc.) through the Spring.
Will there be any improvements seen to the following direction of travel: The congestion resulting from drivers coming North on I-35, then taking the exit to I-435 West who have to quickly get over 2 lanes of high speed traffic to avoid inadvertently exiting at Lackman Rd or K-10?
Yes. Improvements in this area will alleviate the need for drivers to have to cross 2 lanes so quickly.
Will there be any improvements seen to the following direction of travel: The congestion resulting from drivers coming from Lackman Rd trying to get onto I-435 East while drivers on I-435 heading south-east are trying to get over as quickly as possible to take the exit for I-35 South?
Yes. The improvements at this area are among the most significant improvements in the whole project area.
What effort(s) will be taken by KDOT to minimize the amount of congestion and traffic backups resulting from this construction, such as overnight or weekend work?
KDOT is committed to keeping you informed about construction and traffic impacts. The project website: www.jocogateway.com will be the primary location for up-to-date information about the project. Project communication will be shared via traffic alerts, Twitter, Facebook, text messages and electronic project updates. While you will see night and weekend work, this is a very large project and some of that work will be in addition to what will be going on during the day in order to get everything done in 2.5 years.
Will afternoon rush hour drivers coming North on I-35 from Olathe toward Lenexa who use the I-435 West exit ramp to go to 87th Street be impacted by this construction in the evening?
Yes. This ramp is scheduled to be closed for up to 45 days during construction. Closer to the date of the closure, the website will have that information posted and we will be providing that information through traffic alerts, social media updates and text messages. Be sure to sign up on the project website for text messages.
Will morning rush hour drivers coming from Lenexa who use I-435 South to get onto I-35 South to head towards Olathe be impacted by the Lackman Road/435 construction?
The ramp at that location will not be closed, but you will likely see traffic back-ups in that area during construction.
Are the lane closures going to impact drivers using Lackman Road to get onto I-435 or drivers I-435 getting off at Lackman Road or both?
Yes both directions will be impacted at various times throughout the project.
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.
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.
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.
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 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.
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.
All of the improvement options will enhance EMS access into and through the interchange.
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.
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.
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 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.
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 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.
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 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.
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.
KDOT will work with local partners to strike a balance between visually pleasing improvements and fiscally responsible and maintainable improvements.
All current plans take into consideration multimodal transportation solutions and do not preclude future use of transit, bus on shoulders, additional shoulder use, managed lanes or high occupancy transportation (HOT) lanes, ramp metering, etc. Additionally, all current plans allow for future bike and pedestrian access for crossings on the local street network so the highway is viewed as less of a barrier for transportation. Additional transit routes do not fully address the capacity needs of the interchange area. In other words, adding additional buses alone will not reduce congestion enough.
KDOT has conducted a series of focus groups, workshops and online surveys to gather input from stakeholders and the public on project priorities and traffic impacts during construction. We also worked with our Advisory Group and local communities to discuss input and issues over the past several years, beginning with the Concept Study. The input gathered from these activities will influence requirements in the Request for Proposals (RFP), such as Maintenance of Traffic. For example, the input received helped establish a framework for levels of tolerance for the traveling public that will help put parameters on how long portions of the roadway network can be closed. We understand there will be inconveniences during construction and the input received will help KDOT communicate more effectively and efficiently with the traveling public and its stakeholders.
1.27M square yards for the entire Project. This includes the yet-to-be-determined Blue Phase.
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.
Broad guidance will be provided.
Yes, 10% of the RFP amount. There is also a trainee goal of 10,000 hours.
KDOT and the City of Lenexa have agreed to include this project as part of the Phase 2 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.
In general, KDOT design criteria will be used on the Project.
Tolling is not a part of this Project.
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.
Yes. KDOT and the cities of Olathe and Lenexa have agreed to include this project as part of the Phase 2 Project.
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.
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.
Construction is anticipated to start by Summer 2014.
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, this work is currently underway with preliminary engineering.
The right of way footprint is currently being established as part of preliminary engineering.
KDOT will use a fixed price/best design procurement strategy for this Project.
The final budget for the Gateway RFP will be $285 million. The Design-Build teams are competing to provide the best project for that $285 million fixed budget. The final budget now includes the T-WORKS construction funding of $250 million, additional funding from local participants and funding for design and engineering work. KDOT is confident that we will receive a great project for the budget.
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
