Projects - Bridges

In 2008, Wadsworth will construct a new bridge structure at 3300 south over I-215 due to structural deficiencies of the old bridge. Similar to the 4500 SouthBridge over I-215 bridge replacement, a 2.5-million pound pre-constructed bridge structure will be moved into place over one weekend. The transporting of the massive structure requires the use of Self Propelled Modular Transporters (SPMTs), which are multiple axle systems with motors on each axle. Like most of Wadsworth?s structures, thenew bridge walls will feature an aesthetic package that will include full-height sculpted murals with mountain and wild life themes that will provide a context sensitive tie-in with the surrounding environment.

The purpose of this project was to replace the aging and substandard 4500 SouthBridge over I-215 due to structural deficiencies, using special Accelerated Bridge Construction (ABC) cutting-edge practices and techniques. The ABC technique started with the prefabrication of a new bridge that was adjacent to the old structure. After the removal of the existing bridge, Self Propelled Modular Transporters (SPMTs), which are multiple axle systems with motors on each axle, moved the new 3-million pound bridge into place. The 175 foot single span structure replaced the existing 4-span structure, thereby eliminating the need for the three piers and slope protection. The new bridge abutment wall aesthetic package included full-height sculpted murals with mountain themes that provided a context sensitive tie-in with the Olympus Cove backdrop and surrounding environment. Using ABC, the removal of the old bridge and placement of the new bridge was completed within a 52 hour period, dramatically decreasing freeway traffic interruptions which usually last for months using more traditional bridge construction methods.

Moab?s color country now features a new structure allowing pedestrians and recreational users to safely cross over the majestic Colorado River. This structure which was completed in 2008 consists of a three-span steel pedestrian bridge. Crews had to construct a temporary working platform to install the two columns and the three spans in the river. All went as planned and actually finished ahead of schedule. The bridge is constructed of weather-resistant steel and a concrete riding surface which reduces maintenance but which preserves the original beauty of the structure.

This emergency, fast-track design-build project consisted of removing and replacing three existing, single-span bridges over the Moody and Santa Clara rivers that were damaged during the 2005 floods. The project included bridge and roadway design, bridge scour analysis, contractor-furnished quality control, bridge demolition, pile driving, structural concrete, drainage improvements, traffic control, utility relocation, roadway reconstruction, guardrail, fencing, riprap, and asphalt pavement. The new bridges are single span, composite pre-cast concrete girder structures supported by H-piles. Site conditions included severely damaged bridges on the banks of remote sections of the Moody and Santa Clara rivers. The existing bridge abutments were undermined due to severe scouring during the flooding. Access was minimal due to the destruction of the bridges and the severely damaged river channels.

RLW and Baker teamed up on this design-build project to construct two reinforced concrete box girder bridges in an environmentally sensitive area. This project was the result of a new roadway that required two bridges to preserve existing grades and vegetation. The project entailed the design and construction of a 450-foot-long, 5-span curved bridge and another 150-foot-long, two-span curved bridge. Both bridges have a centerline radius of 76 feet and are on a 12 percent grade. Baker supplied plans and specifications and evaluated construction alternatives to avoid impacting a conservation easement. Baker also provided 4-D visual simulations, drive through simulations, fly around simulations, and photo match renderings to evaluate aesthetic treatments. RLW overcame the challenge of constructing a cast-in-place structure on an approximate 30% slope grade, while staying within the adjacent conservation easement. Both bridges were built throughout severe winter conditions.

The project features one of the largest steel girder structures in Utah. The girders are fabricated with special ?Corten? steel. This type of steel provides a natural rust colored finish, providing weather resistance as well as contrast to the natural concrete. The bridge consists of a 3-span structure that towers in front of the Deer Creek dam/spillway and is the final stage of multiple design features that provides a safer travel experience - adjacent to the recently completed Deer Creek dam seismic improvement project.

Vice President Ty Wadsworth served as the Project Manager for this privately owned Design Build Project. His construction crew worked to create and build the new Bridge in the ?out skirts? of Santaquin, Utah for the new Summit Ridge subdivision. The bridge allows traffic to flow steadily over the railroad tracks. This design build project also aesthetically incorporates the subdivision?s name engraved in the concrete artwork.

This privately owned Design-Build Project was jointly managed by Project Manager Gaylen Stewart and Vice President Con Wadsworth. RLWs Crew worked to create and build this new Bridge just outside of Lehi, Utah for the new Traverse Mountain Planned Community. The community includes many new retail stores such as the Cabela?s sporting goods chain. The bridge allows the increasing traffic to flow steadily under the railroad tracks.
