- Zero safety incidents
Tooele County is one of the fastest-growing counties in Utah. The project has significantly improved mobility and provides a smoother, safer continuous auxiliary lane for the 40,000-plus motorists who drive on it daily. The enhancements improve the traffic flow by adding a new exit-only lane on westbound I-80 and an auxiliary lane from the off-ramp of State Road 201 to the on-ramp of State Road 36. The new auxiliary lane connects the off ramp at SR-201 and the on ramp to SR-36 in one continuous lane, allowing for a safer, more efficient commute through this area.
The project team met a 2020 opening goal and completed the project six months ahead of schedule with zero rework, all during the height of the COVID-19 pandemic. This is a testament to the project team’s dedication to safety, quality and thorough activity planning.
The team relied on 3D modeling to save time, improve precision, and reduce waste. Additionally, through proactive planning, close subcontractor coordination, and partnership with the supplier to expedite long-lead materials needed for the project, Sundt’s team accelerated the schedule.
In an effort to ensure the integrity and longevity of the new roadway, the project removed unsuitable sections of the existing grade and replaced it with crushed concrete layers reinforced with geotextile high-strength fabric.
The project team also worked closely with local governments and organizations, including the Daughters of the Utah Pioneers, to move two historical Oregon Trail markers to a new site nearby when they were impacted by the closure of viewing areas along the westbound I-80.
UDOT’s vision for good health, better mobility, strong economy and connected communities are encapsulated by the I-80 project. Emergency services and daily commutes are no longer threatened by a traffic chokepoint, and these changes support the region’s growth.
