Design-Build Information

Download the MoDOT Design-Build flyer by clicking here.


As per Sec. 227.107, RSMo, MoDOT was given the authority for three pilot projects using the design-build project delivery technique: The New I-64, kcICON and the Safe & Sound Bridge Improvement Program. Each was completed ahead of schedule and on, or under, budget.

Subsequently, the statute was amended to give MoDOT the opportunity to enter into design-build contracts on no more than two percent of the total number of all state highway system projects awarded to contracts for construction from projects listed in the commission’s approved statewide transportation improvement project for that state fiscal year.

Design-build is a delivery method that includes hiring one contracting team to complete the design work and build the highway improvement under one contract. MoDOT provides the project goals, budget and schedule and the contractor team completes the work. This technique has been known to significantly save time and provide cost savings.

Design-Build Projects in Procurement


Aug. 14, 2020 – For immediate release        

MoDOT Takes the Next Step to Building a New Buck O’Neil Bridge

JACKSON/CLAY COUNTIES After an extensive and exhaustive evaluation process, the Missouri Department of Transportation has developed a list of qualified design-build teams to compete for the contract to build a new U.S. Route 169 Buck O’Neil Bridge. Each of the teams come from a diverse mix of experienced local and national companies who submitted exceptional proposals.

“We are excited about the interest we have received in the project. Five teams have been selected to compete for the contract to oversee the design and construction of this bridge project,” said MoDOT Project Director Mary Miller.

The following teams (in no particular order) were selected to further develop their proposals on the project:

  • American Bridge/Parsons Team
  • Lunda Construction Co.
  • Massman-Clarkson, a joint venture
  • Traylor Ames Joint Venture
  • The Walsh Design-Build Team

Design-build projects combine both the design and construction phases into one contract. The selected contract team completes the design and construction in parallel instead of in succession, which saves time and resources.

From this group, the Missouri Highways and Transportation Commission will select a best-value proposal from a design-build team to deliver the project. The selection is expected in February 2021, with construction beginning later that year.

The John Jordan “Buck” O’Neil Memorial Bridge (formerly the Broadway Bridge), is a triple arch bridge carrying U.S. 169 over the Missouri River, and serves as a key regional connection between downtown Kansas City and communities north of the river.

While safe, the bridge is nearing the end of its projected lifespan. Opened in 1956, the bridge recently celebrated its 60th year of operation. 

Since that time, neighborhoods and communities on both sides of the bridge have changed significantly and now nearly 50,000 vehicles use the bridge daily.

“Thank you to everyone who expressed interest and put in the time and effort to deliver a SOQ for consideration,” Miller added.

Project Goals:

  1. Construct an innovative, low-maintenance Missouri River Bridge that will provide a century of service within the program budget of $247.5 million.
  2. Provide a safe, connective and accessible transportation facility that improves regional and local system performance.
  3. Manage the impact to the travelling public during construction. 
  4. Complete the project by December 1, 2024, utilizing a diverse workforce.

Upcoming Design-Build Projects


    The Central District Americans with Disabilities Act project will bring specific ADA pedestrian facilities located throughout the district into compliance to the maximum extent feasible in accordance with MoDOT Standards and the Public Right of Way Accessibility Guidelines.  For more information, Project Director Chris Brownell at, or (573) 526-4567.


    Mid MO ADA Project Status Update

    The Mid MO ADA Design-Build Project was postponed in April of this year due to anticipated loss of MoDOT’s fuel tax revenue as a result of the national shutdown of businesses surrounding the national pandemic.  MoDOT was tasked by the US DOT to keep our STIP projects moving forward as planned.  This project was moved out to a later fiscal year to help alleviate Central District revenue losses in the short term.  Currently, the Mid MO ADA Project has been placed in the first quarter of fiscal year 2022 and Central District is committed to maintain this award date.  Team meetings are again underway and the project is moving forward to a project advertisement later in 2020 or early 2021.  As the project progresses and more details are ready to be shared, they will be posted on the project website at


    Project Goals:

    1. Deliver the project within the program budget of $13.6 million.

    2. Bring designated pedestrian facilities into ADA compliance.

    3. Use innovation to maximize improvements that provide a long-lasting and safe pedestrian facility.

    4. Safely deliver a project that minimizes and mitigates construction impacts through construction staging and communication efforts.

    5. Complete the project no later than December 1, 2022.




    Projects with Scoping Only


    The purpose of this section is to identify potential future highway and bridge projects. These projects may be in the evaluation stage, which is called project scoping, or may be further along in the preliminary design process. Projects listed in this section are not commitments to construct or implement an improvement. These commitments won’t be made until the NEPA process is completed. These projects are being included in the STIP for the scoping or preliminary design phase only, and subsequent phases have not yet been determined or are beyond the STIP horizon period.
