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


Feb. 3, 2021 – For immediate release

Massman-Clarkson selected as design-build team for the new Buck O’Neil Bridge in Kansas City


LEE’S SUMMIT – The Missouri Highways and Transportation Commission today selected Massman-Clarkson, A Joint Venture for the design-build contract to replace the Buck O’Neil Bridge, formally known as the Broadway Bridge. Construction is anticipated to begin in spring of 2022 and be fully completed by late fall of 2024.

“We are thrilled by the decision and look forward to working with Massman-Clarkson, A Joint Venture,” said Missouri Department of Transportation Kansas City District Engineer Dave Silvester. “This is such an important regional project that wouldn’t happen without the partnership between the City of Kansas City and MoDOT. We expect great things from this successful team effort.”

Massman-Clarkson, A Joint Venture competed against two other design-build teams (American Bridge and Traylor-Ames), both of whom had local and national experience. Their dynamic project proposal demonstrated a best-value design for the City of Kansas City, which made them the top choice. The Massman-Clarkson team includes the following firms: Massman Construction Co., Clarkson Construction Co. and HNTB Corporation – all of Kansas City.

The winning contractor had to meet or exceed several goals, which included: providing a direct connection between U.S. Route 169 to Interstate 35, building a new bridge that can be reasonably maintained and will provide a century of service, and minimizing the impact to the travelling public during construction.

“This is a significant milestone for the project, and the City of Kansas City is glad to see this progress,” said City Manager Brian Platt. “We will continue working with the state to ensure the project employs a diverse workforce as we build this vital and transformative economic link between downtown KCMO and our northland region. This will benefit our residents and visitors by adding bike and pedestrian facilities, improving access to the downtown airport and decreasing traffic congestion, especially on our local streets.”

The new Missouri river bridge will cost close to $220 million dollars to construct and will provide a safe, connective and accessible transportation facility that improves regional and local system performance.

The John Jordan “Buck” O’Neil Memorial Bridge is a triple arch bridge carrying U.S. Route 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 service life. Opened in 1956, the bridge is nearly 65 years old. Nearly 50,000 vehicles use the bridge daily.

MoDOT Moves Ones Step Closer to Building a New Rocheport Bridge

JEFFERSON CITY – Following an extensive evaluation process, four qualified teams have been selected to compete for the contract to design and construct a new Missouri River Bridge on Interstate 70 near Rocheport.

The Missouri Department of Transportation has received Statements of Qualification from potential design-build teams for the Rocheport Bridge project.

     “We are very pleased with the interest we received in working on the Rocheport Bridge project. The four short-listed teams are all very experienced and capable of producing a successful project,” said Project Director Brandi Baldwin. “We look forward to moving forward in the process and selecting the final design-build team.” 

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

  • Traylor-Ames Joint Venture Team - Traylor Brothers, Inc.; Jacobs Engineering Group, Inc.; Ames Construction, Inc.
  • American Bridge/Garver Team - American Bridge Company; Garver, LLC; Hg Consult, Inc.; Terracon
  • Rocheport Bridge Constructors - Massman Construction Company; HNTB Corporation; Emery Sapp & Sons, Inc.
  • Lunda Team - Lunda Construction Co.; Parsons Transportation Group, Inc.; Dan Brown & Associates; Hugh Zeng United

There are still opportunities for additional consultants and subcontracting firms to be added to each team. A networking opportunity for Disadvantaged Business Enterprises will be offered this spring.

Design-build projects combine both the design and construction phases into one contract. The selected team completes the design and construction in parallel instead of in succession. MoDOT provides the project goals, budget and schedule, and the contractor team conducts the work. This technique has been known to significantly save time and money. For more information about design-build or to see other similar project across the state, visit

This $240 million project was made possible by the July 2019 award of a $81.2 million Infrastructure for Rebuilding America (INFRA) grant from the U.S. Department of Transportation. The project will replace the existing I-70 bridge as well as reconstruct the Route BB interchange just east of the bridge.

MoDOT has established design-build goals for the project. The contractor team will be selected using an apparent best-value process to determine the team who can best meet or beat the goals.  To view the full list of goals and project timeline visit

MoDOT will issue the request for proposal later this month. Proposals will be due in June and the design-build team is expected to be selected in July, with construction beginning as early as later this year with completion by the end of 2024.

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.
