Project Overview

The I-15 Nephi Bridges project is a $17.8 million project that is part of UDOT’s effort to preserve infrastructure and extend the life of the pavement and bridges across the state. This project occurs along a 19-mile stretch of I-15 through Nephi and will replace two existing bridge decks, repair nine other bridges, and replace sections of concrete pavement. 

Work and traffic impacts are expected daily and construction is anticipated to last through spring 2024.

I-15 through Nephi is an active construction zone with reduced speed limits, lane closures, and traffic delays. Please plan for extra travel time and slow down for the safety of yourself and the construction crews.

See the "Traffic Impacts" tab for more details!
