Summit County Improved Project

Project Overview

UDOT is working on a four-fold project that encompasses areas around I-80 at Kimball Junction, the westbound US-40 to westbound I-80 flyover, eastbound and westbound US-40 (between SR-248 and I-80), and the SR-248 interchange. Construction crews will improve drainage and ride quality, reduce congestion, and preserve the underlying infrastructure of asphalt and concrete roadways.

Work began in June 2024 and is currently in a wintertime suspension. Elements of the project at the US-40/SR-248 interchange require warmer temperatures. Work to place a surface treatment at the interchange will take place in the spring of 2025.
