UDOT made the final modification to I-15 Tech Corridor and completed a 10-year expansion project



LEHI — For Utah drivers, their ten-year highway construction journey may finally be over.

The Utah Department of Transportation announced Friday the completion of the I-15 technical corridor project, which will extend the highway from four lanes between Lehi Main Street and Interstate 92 to six lanes. This milestone marks the final phase of I-15 reconstruction over the past ten years, in Utah in northern Utah, which has increased the capacity of vehicles on the road from the Bangerter Highway to the Spanish fork.

This latest project cost $415 million and includes the state’s first one-way frontage road system, as well as two redesigned overpasses and new trails for pedestrians and cyclists.

UDOT project director Boyd Humphreys (Boyd Humphreys) said: “Before the project started, there was a bottleneck in this 4-mile section. Now, we have eliminated this bottleneck.”

; “We plan to travel time throughout the project. See the benefits in the process, which will enable people to better enter the area.”

The I-15 Technical Corridor started in May 2018. Together with the I-15 CORE project, The Point project and the Access Utah County project, it is considered the last part of the reconstruction of the highway in northern Utah. All work was completed in 2010. Said that the cost is only slightly more than 2.1 billion US dollars.

He pointed out that although the COVID-19 pandemic has had a great negative impact on the Wasatch front line, at the beginning of the outbreak, the flight attendants used fewer vehicles to complete more work.

“During this time, we were able to close some lanes and do things that are usually not possible due to heavy traffic, so there are indeed some benefits that really help the project,” he said.

UDOT stated that some of the remaining work will require the closure of the carriageway by mid-November to complete the installation of multi-purpose trails for pedestrians and cyclists, including a new pedestrian bridge and tunnel, as well as existing local and regional trails.

Humphries said that as the highway widens, drivers may feel a greater sense of openness, which may affect their driving style. He urged drivers to be extra careful when entering the highway.

He said: “People should follow the speed limit and drive out of there safely.” “Yes, the lane is open, it feels like you can drive fast, but we want people to be safe.”

UDOT spokesperson John Gleason said that the additional lanes on I-15 are designed to keep traffic flowing in busy areas and improve the quality of life of residents and commuters. He added that the travel time from the corner of the mountain to Lehi Street in the afternoon commute will be reduced by as much as 50%, which will benefit the increasing number of vehicles driving in and around northern Utah.

For us, staying ahead is very important. Important-able to deal with the future and provide the best transportation system.”

According to the press release, these bridges have been redesigned to accommodate the new lanes on I-15, frontage road systems and new active traffic functions, which are designed to last for 75 years.

He said: “When you look at the changes in Lehi in the past ten years, it is really amazing. It has gone from a small town to one of the technology centers in the world today.” “This is really a point, so we To ensure that we are doing everything we can to cope with this growth, and to ensure that highways and national highways are ready to accommodate the growth we are seeing here, and we will continue to look at it.”
