By Irwin Rapoport CEG CORRESPONDENT

The Colorado Department of Transportation (CDOT) is investing $114 million to upgrade the Interstate 25 and U.S. Highway 50B interchange in Pueblo to improve safety and traffic on roads built in the 1950s.

SEMA Construction began working in December 2024 and will have crews on-site until summer 2027.

The project is financed by Colorado Bridge and Tunnel Enterprise, among other sources.

The work zone covers I-25 from mile point 99.7 to 101.4 and U.S. 50B from mile point 315.9 to 316.6.

Crews are building five new bridge structures, retaining noise walls, embankments, drainage and erosion control along the impacted roadway, as well as reconstructing the

roadway, ramps and other safety improvements.

The new interchange will address deteriorating roadways and bridges and non-standard road characteristics on I-25. The bridge structure over I-25 does not meet current standards. And it will improve local and regional mobility within and through the city of Pueblo, meeting existing and future travel demands.

“The new I-25/U.S. 50B interchange is a priority for CDOT because the current interchange poses safety concerns with many trucks on the interstate hitting the low clearance bridge or getting stuck on the interchange itself,” said Shane Ferguson, CDOT Region 2 transportation director. “The new diverging diamond interchange [DDI] will help improve traffic flow on this important freight corridor and increase safety and mobility for all road users.”

When completed, the new interchange will be just north see INTERCHANGE page 6

UAPA Hosts Successful Utah Asphalt Conference 2025

T

he Utah Asphalt Conference (UAC) 2025, hosted by the Utah Asphalt Pavement Association (UAPA), marked a successful event under new leadership.

Held on Feb. 19-20 at the Mountain America Expo Center in Sandy, Utah, the conference saw increased attendance, strong sponsorship support and positive feedback from participants.

Rick Johnson, UAPA’s new executive director, who assumed the role in June 2024, expressed his enthusiasm for the event’s achievements.

“Sponsorships and attendance were up this year, and the feedback from people has been overwhelmingly positive,” he said.

The conference featured more than 28 educational seminars and a comprehensive trade show. The conference offered 35 classes, where 800 attendees earned Continuing (L-R): Sy Harrison, Paul Jeo, Wyatt Davis and Christel Education (CE) credits for their professional development. of Sync Aggregate were ready to discuss your Attendance surpassed previous years, with more than 1,100 Fuentes project. registered participants and an additional 300 local high school students engaging in the event — a testament to the industry’s outreach efforts and focus on workforce development, according to Johnson.

The conference began with breakfast and a keynote address from Carlos Braceras, executive director of the Utah Department of Transportation (UDOT), who provided insights into the future of Utah’s transportation infrastructure.

The trade show floor featured exhibitors showcasing essential services such as asphalt maintenance, paving, repair, seal coating, crack sealing and striping and marking — highlighting the industry’s ongoing commitment to quality and innovation.

A standout moment of the event was a successful raffle supporting UAPA’s scholarship fund, which awarded four $1,500 scholarships to local students pursuing degrees in horizontal construction.

With its programming, enhanced attendance and impactful networking opportunities, UAC 2025 reaffirmed its role as a cornerstone event for advancing Utah’s asphalt and construction industries.  CEG (All photographs in this article are Copyright 2025 Construction Equipment Guide.

Mayo Clinic Announces $1.9B Expansion of Phoenix Campus

While the Mayo Clinic's $5 billion Unbound developments in downtown Rochester, Minn., is the famed medical center’s larger program, it’s also spending $1.9 billion to expand its Phoenix, Ariz., campus, according to postbulletin.com.

Mayo Clinic will expand its campus in Phoenix and add 1.2 million sq. ft. of space by significantly expanding an existing building and constructing a new one.

Crews Build Five New Bridges as Part of Pueblo Project INTERCHANGE from page 1

of the existing location and operate as a DDI to increase safety and mobility for drivers.

Approximately 30,000 vehicles use the interchange daily.

The lifespan of the bridges will be 80 years.

In 2000, the Federal Highway Administration (FHWA) and CDOT initiated a study of I-25 through Pueblo.

“The study process analyzed transportation conditions and identified transportation needs in the 7-mi. corridor from just south of Pueblo Boulevard to just south of the U.S. 50/CO 47 Interchange,” Ferguson said.

“This is the second project to be built as part of that study.”

The project was designed by AtkinsRealis.

Construction activity is occurring adjacent to the roadway to minimize the impacts on I-25 and U.S. 50 traffic during the first year of construction.

SEMA Construction efforts thus far have focused on structures, earthwork and drainage, with crews using Cat excavators (317s, 352s and 328s), drill rigs; a Cat D6 dozer; Cat 950 and 960 loaders, a Cat 140M motor grader, and Cat 745 articulated trucks. “[The challenges include] construction coordination with railroads, work near Fountain Creek, dewatering and complex

NM House Committee Passes $1.5B Road Funding Legislation A bipartisan bill authorizing $1.5 billion in transportation bonds cleared its first legislative hurdle on Feb. 20, 2025, winning unanimous approval from the House Transportation, Public Works & Capital Improvements Committee to help address New Mexico’s $5.6 billion road funding shortfall.

The House Appropriations and Finance Committee will next consider House Bill 145, sponsored by Reps. Dayan Hochman-Vigil, Patricia A. Lundstrom, Art De La Cruz, Cathrynn N. Brown and Nathan P. Small. The legislation would empower the State Transportation Commission to issue bonds for highway projects, backed by federal funds and state transportation taxes.

“This bipartisan legislation represents a smart, fiscally responsible approach to funding our state’s critical transportation infrastructure needs,” said Rebecca Roose, infrastructure advisor for Gov. Michelle Lujan Grisham. “I want to thank Reps.

Hochman-Vigil, De La Cruz, Lundstrom, Brown and Small for their leadership.”

In January, a TRIP report revealed that 57 percent of state and local roads are in poor or mediocre condition, costing New Mexico drivers $3.6 billion annually.

“We can’t afford to fall further behind in tackling the list of road projects needed statewide,” said NMDOT Cabinet Secretary Ricky Serna. “This bonding creates sustainable and adequate funding for roads in New Mexico.”

Under HB 145, total outstanding bonds cannot exceed $1.12 billion. Eligible projects would be identified through the Statewide Transportation Improvement Program.

The department of transportation relies on two main funding sources: federal government allocations and the State Road Fund, which draws revenue from fuel taxes, vehicle registration and truck weight fees.

The bond authorization aims to address several mounting challenges associated with increased construction costs and projected decreases in road fund revenues. 
