Public-Private Partnership Delivers Innovative Interchange and Savings
New Interchange at US 50/63 and East McCarty Street; Civil and Site for Commercial Development
The project was championed by a unique public-private partnership between Jefferson City, Cole County, the Missouri Department of Transportation (MoDOT) and a national retailer. As a regular consultant to MoDOT and the retailer, Crawford, Murphy & Tilly (CMT) was able to call upon its fluency in both entity’s procedures and design requirements to execute the many complex aspects of the project which involved design of the interchange in tandem with civil and site design for the 30-acre retail development.
Key to the project’s success was the use of innovative funding mechanisms, including the creation of a transportation development district (TDD), participation by the MoDOT Cost Share Program and local funding.
Another aspect that made the public-private partnership ideal was the remarkable compatibility in earthwork needs between the interchange project and the retailers site development that resulted in a combined site savings of $2.5 million.
The project also features the first parclo interchange with roundabouts in Missouri and the first known two-quadrant type-A Parclo interchange with roundabouts in the US. In designing the interchange, CMT employed MoDOT’s Practical Design philosophy to reduce costs without compromising safety and meeting the purpose and need of the project, resulting in a savings of approximately $1.4 million in public funds.
