Sacaton Road Bridge Replacement Project Receives ENR Southwest Merit Award

The Sacaton Road Bridge Replacement project recently received an Award of Merit: Highway/Bridge from ENR Southwest. The Sacaton Road Bridge was the first Accelerated Bridge Construction (ABC)/slide-in type or preassembled bridge structure built on Arizona tribal lands. The project utilized the SHRP-2 toolkit (Strategic Highway Research Program), and the Construction Manager/General Contractor (CM/GC) delivery process.

The two-span structure extents across the Gila River, acting as the main outlet to the Phoenix area and connects the Gila River Indian Community to SR-87. The old bridge, built in 1961, was frequently overtopped during rain events, and the community sought a new bridge to improve roadway safety and hydraulic capacity.

Horrocks Engineers provided consulting services out of our Phoenix office and worked closely with FNF Construction, who served as CM/GC.

Horrocks Takes First Place with I-84 Mainline, Interchange, and Railroad Bridges Project

The American Council of Engineering Companies (ACEC) of Idaho recently announced that Horrocks Engineers’ I-84, Broadway Avenue Interchange, and Gowen Railroad Spur Bridges project will receive First Place in Category H, Transportation, for the 2015 Engineering Excellence Awards Competition.

Broadway ICHorrocks recently completed this project out of our Nampa, Idaho office. Bryan Foote, Operations Manager of Horrocks’ Nampa office and Project Manager for the project, led a team of talented professionals who worked closely with the Idaho Transportation Department (ITD) and Connecting Idaho Partners (CIP) to provide design services.

The I-84, Broadway Avenue Interchange, and Gowen Railroad Bridges project consisted of three separate projects; I-84 Mainline, Broadway Avenue Interchange, and Eastbound and Westbound I-84 bridges over the UPRR Gowen Railroad Spur Bridges.

Improvements included reconstructing and replacing the Broadway Interchange with a Single-Point Urban Interchange (SPUI), reconstructing the existing two lanes of I-84 in each direction for .75 miles with a new concrete surface west of Broadway Avenue, asphalt surfacing east of Broadway Avenue, and reconstructing and widening the I-84 bridges over the Gowen Railroad Spur.

This project improved traffic operation performance, pavement condition, and increased capacity to meet current and future needs. The methods and innovative solutions developed by the Horrocks team addressed risks early in the design process, reduced construction costs, and minimized impacts to the traveling public, resulting in a successfully delivered project.

Final plan, specification, and estimate (PS&E) was completed October 30th, 2013, on schedule and under budget.

The Horrocks team implemented several significant project innovations on this project, including:

  • SPUI Design — Horrocks developed a compressed SPUI design which fit within the existing right-of-way and avoided additional cost and delays associated with right-of-way acquisition
  • Companioning Projects — Companioning the Broadway Interchange, I-84 Bridges over the Gowen Railroad Spur, and I-84 Mainline into one construction project helped avoid conflicts and gain construction efficiencies
  • Bridge Piles — The Horrocks team drove test piles during the design phase to better define pile capacity, anticipate pile depths, and minimize ITD’s risk of pile quantity over/underrun during construction
  • Synchronized Construction — Developing a single construction phasing plan synchronized with the adjacent and concurrent Gowen Road Interchange project minimized impacts to the traveling public
  • Contract Milestones — Incorporating intermediate contract milestones with incentives for completion reduced the construction schedule and claim liability

Springville City’s Wayne Bartholomew Park Awarded “2015 Most Outstanding Project” for Landscape/Public Space (Small)


Utah Construction & Design (UC&D) recently awarded Springville City the 2015 Most Outstanding Project in Landscape/Public Space (Small) in recognition of Wayne Bartholomew Park. The park’s main attraction is a large pond spanning three acres long and 15 feet deep at its deepest, a sandy beach for swimming access and sunbathing, five pavilions, ample grass area with trees for shade, restrooms, changing rooms, a concession stand, a large plaza, a trail around the pond, fishing docks, designated areas to play volleyball or badminton, and striking mountain views. The City secured room for future expansion and already has plans to add larger pavilions and playgrounds. Horrocks worked closely with Logan Simpson Design and Springville City to complete this project with very limited budget and time.

Horrocks Engineers provided utility design, parking layout design, grading design, and stormwater design. In addition to standard stormwater services, Horrocks designed bioswales (landscape elements designed to remove silt and pollution from surface runoff water) to reduce runoff through landscaped drainage ways. The parking lot proved challenging due to its compound curve shape—no two lines are parallel.

Additionally, all public and private stakeholders on the project remained actively involved. One of these stakeholders was the San Carlos Apache Tribe. The rest area is located on the Tribe’s reservation and once the project was complete, the Tribe blessed the new building.

Each year, the Arizona Transportation Partnering Excellence Award is given to project teams who successfully apply partnering principles and processes within the transportation industry. A panel of government agencies, contractors, and consultants judge each project application based on criteria including charter/mission of the project team, goals, issue resolution, teamwork, and value/outcomes.

The team will be presented with the award at the 64th Annual Roads and Streets Conference in April. Horrocks is honored to be part of such a great team!

Horrocks Engineers Wins Three Separate “Best Projects” ENR Awards

Horrocks Engineers was selected as the winner of three separate ENR “Best Project” awards in the Intermountain Area (Utah, Montana, and Idaho) for Highways/Bridges, Landscape/Urban Development, and Small Project (Under $10 Million).

Highways/Bridges Best Project: St. George Boulevard Interchange at Milepost 8, St. George, Utah



This project focused on upgrading the traditional interchange at I-15 Milepost 8 into a Diverging Diamond Interchange (DDI), structure rehabilitation, and an inclusion of a pedestrian facility.

Horrocks designed the new intersection, widened the existing bridge over I-15 at St. George Blvd, reconfigured the existing Milepost 8 interchange into a Diverging Diamond Interchange, and widened the roadway to provide standard 12-foot lanes along with 10-foot shoulders. Horrocks was additionally responsible for performing signal coordination, right-of-way and utility coordination, maintenance of traffic (MOT) modeling, and maintenance of business access in each direction during construction.

This project was a part of the I-15; MP 0-16 Environmental Assessment (EA), and is the first priority project to receive funding. The study showed that the interchange, in its origional configuration, would have fail by 2040. The Preferred Alternative for the EA was to convert the existing diamond interchange to a Diverging Diamond Interchange (DDI) to accommodate the projected 2040 travel demand.


Landscape/Urban Development Best Project: Lions Park Transit Hub and Colorado River Pathway, Moab, Utah

Lions Park

The Lions Park Transit Hub and CRP Trail project is part of the Moab Canyon Pathway, a paved trail system that connects Moab to Arches National Park, Canyonlands National Park, and Dead Horse Point State Park. The completed development consists of one pedestrian tunnel, one pre-engineered restroom building, one shade structure, one pedestrian bridge, three elevated bridges, 12 retaining walls, a new section of trail, and a new transit hub.

The new section of pathway spans for two miles along the banks of the Colorado River and ranges in width from 8 – 12 feet. Certain areas along the river had very limited and sometimes insufficient space for trail placement. Rather than cut into the towering red-rock cliffs Moab is known for, Horrocks industrialized a unique solution to implement Accelerated Bridge Construction (ABC) techniques and raise the trail above the river bank using an elevated trail bridge system. This allowed for the preservation of the river, red-rock cliffs, and the existing road.


Small Project (Under $10 Million) Best Project: SH-44, Linder to Ballantyne Design-Build, Eagle, Idaho

The Central Paving/Horrocks Engineers Design-Build Team was successfully selected by the Idaho Transportation Department (ITD) to complete the SH-44, Linder Road to Ballantyne Lane project in Idaho. This is ITD’s first ever design-build project and Horrocks is proud to be involved in this historic undertaking. Drawing on Horrocks’ previous design-build experience, our team worked closely with ITD to help expand and develop their design-build program while meeting the Department’s project goals. This 1.75 mile project reconstructed the intersection of Linder Road and SH-44, and SH-44 from Linder Road to Ballantyne Lane, and widened the existing three-lane roadway to five lanes.

The intersection of Linder Road and SH-44 was improved to provide two left-turn lanes along with two through lanes. This project included signalization of three intersections, widening of the existing Middleton Mill Canal bridge structure, drainage, utility coordination, and environmental resolution.

To complete the project efficiently and minimize impacts to the traveling public, the team implemented a carefully sequenced project phasing and staging plan while utilizing innovations. These efforts included the CRABS pavement rehabilitation process, installation of temporary pavement and signals at intersections, night-time construction activities, and continual public involvement efforts to inform roadway users of construction progress.
