Frequently Asked Questions

The project will use a process known as “box jacking” to install the new underpass without any service interruptions to the trains. This innovation, developed in Italy, involves placing a temporary bridge (the Verona Method) to support the rails while the box that will serve as the underpass for 14600 South is gradually pushed or jacked beneath. This is the first time this process has been used in the United States.

This construction method is necessary to prevent service disruptions to both Union Pacific Railroad and the UTA FrontRunner line. 

An Environmental Study is a high-level study that identifies and studies the impacts and large infrastructure projects and determines mitigation measures. These studies are conducted before the design and construction of a project to understand how proposed improvements can be implemented safely and responsibly. Environmental Studies analyze several different factors in an area where improvements are proposed, such as land use, zoning, land acquisition, noise, water, species, archeological resources, and more. Once a decision is made to move forward with a project, further analysis of the environment, such as geotechnical exploration and soil analysis, is performed as part of the design stage.

An environmental study for this project was conducted in 2022. As part of this study, a public meeting was held where the results of the study were provided for public review and comment on December 7, 2022.

As we work on the improvements, increased noise, dust, and vibrations may be present. 

Normal hours of operation are 7:00 a.m. to 5:00 p.m. During the installation of the Verona Method and the Box Push, the contractor will be working around the clock to meet Union Pacific Railroad (UPRR) and Utah Transit Authority (UTA) restrictions.

The crew prioritizes safety and will keep the site clean and contained. 

Vibrations are monitored to stay within safe, typical construction levels. 

Our Emergency Manger has identified alternate routes throughout our community that can be used during emergencies.  Before a safe route can be established, onsite crews will evaluate the area and decide on the safest way for egress and ingress into an area. Like with traffic accidents, any emergency may cause temporary difficulties as crews arrive and assessments are made. 

 A recent example shows how this plan works. On Monday, January 19, 2026, a contractor installing fiber hit a gas line at approximately 1200 West 14600 South. 911 was called at approximately 1:35 pm and immediately dispatched Bluffdale Fire and Police Departments to the scene. Upon arrival, the priority of the crew was to assess and create a controlled area, including evacuating the park and nearby homes. Once the perimeter was established, Fire Chief Matt Evans was able to implement the Emergency Access Plan and by 2:15 pm opened the Jordan River Parkway Trail to allow egress and ingress to Spring View Parkway. Traffic was able to move through this access point until approximately 4:15 pm, when the road to the main entrance was safe to use again.

For immediate concerns, call the 24-hour hotline at 385-247-0775.

Bluffdale is part of a quiet zone with the Federal Railroad Administration (FRA) that includes cities in Salt Lake County and Utah County. However, Union Pacific is federally mandated to give a warning when entering a construction zone. We have no control over how or when they use their horns. They also do not provide information to us about when they will be using their horns.
