WHAT MAKES THE PROJECT UNIQUE U.S. 89 Farmington to I-84 was the first Progressive Design-Build Project in Utah built by Oak Hills Constructors. In Progressive Design-Build Projects, the owner manages only one contract with a single point of responsibility. The designer and contractor work together from the beginning as a team, providing unified project recommendations to fit the owner’s schedule and budget. The project improved connections between U.S. 89 and Main Street, S.R. 193 and Interstate 84. Some sections of new frontage roads were constructed to improve access to existing frontage roads and local streets. These changes improved local traffic access to the new interchanges and cross efficiently. The frontage roads include shared shoulders that will also function as a parallel bicycle route. CHALLENGES AND SUCCESSES This project was scheduled and started right when the COVID-19 pandemic began. Two lanes of traffic in each direction had to be maintained. With COVID and many people being at home, there were not as many cars on the road; some scheduled night shift work was able to happen during the day with the light traffic. The traffic lights had to keep working. The lights at 400 N. and Oak Hills Drive had to be relocated as a temporary fix until the bridges were built. One intersection had over a dozen traffic switches; everything had to be reconstructed while traffic was still moving. In addition to the roadwork, there were many utilities that had to be replaced, and there was a major focus on the pedestrian aspect of this project. PROJECT QUALITY The project team captured $1 million in HMA incentive with only a $4,000 disincentive on the entire project. Over 272,000 tons were placed on the project with the numerous percentages of available bonus earned. 24
