Trail Projects
Klophaus & Associates and it's staff bring the experience of over 20 projects that have developed or created new pedestrian or multi-use trail systems. Structures, whether they are bridges, underpasses, or retaining walls, provide the elements that separates pedestrians from vehicle traffic and creates a safer, more efficient system for active transportation users. As a full service structural engineering firm, specializing in transportation infrastructure, K&A is able to assist UDOT in creating new connections and safer infrastructure for pedestrians, cyclists, and other active transportation users. Our staff's experience is highlighted below:
Parley's Trail Final Phase
This project created the final connection between Parley's Trail and the Jordan River Parkway Trail. The project included 2 prefabricated steel truss bridges. See link below for more project highlights and information.
Parley's Trail over 600 W
K&A designed a 130 ft prefabricated steel truss that spanned 600 W to provide a grade separated crossing for Parley's Trail. The substructure of the existing UTA bridge was modified to support the steel truss. This project required direct coordination with UTA, including scheduling the catenary lines to be de-energized during erection of the bridge.
US-89 and SR-203 TRail
This pedestrian underpass utilized a 150 ft long precast concrete arch. The construction of the underpass was phased to maintain all traffic lanes for US-89 during construction. The project presented many challenges including significant dewatering and temporary shoring.
Big Cottonwood Trail at Wasatch
K&A assisted Perkins Engineering in the layout of stairs, retaining walls, and slope paving modifications that allowed for the Big Cottonwood Trail to continue under Wasatch Blvd. The project required working around existing utilities, protection of the substructure of the existing bridge during a flood event, hydraulic modeling, and verifying adequate vertical clearance is provided.
Tonaquint Park Bridge
This project relocated an existing steel truss bridge to carry the Santa Clara Trail over a dry wash at Tonaquint Park. A new substructure was designed to work with the existing steel truss bridge.
SR-193 and center street Pedestrian Underpass
This pedestrian underpass was designed to use a 88 ft precast concrete arch that supports SR-193. K&A designed and detailed cast in place concrete details for the headwalls and wingwalls that worked with the precast concrete sections.
Jordan River Bridge Over 6200 South
K&A provided erection plans and details for the 280 ft steel truss bridge that spanned over three UPRR rail lines. The work had to occur during a strict closure period and required a splice at 108 ft.
SR-9 Over Multi-Use Trail
K&A worked with UDOT and the National Parks Service to design and construct a grade separated crossing for the Zion National Park visitor's center. Special aesthetics were required on the project including a natural stone veneer applied to the wingwalls to blend in with the surrounding scenery.
In addition to the projects noted above, K&A staff have also been involved in the design of the following projects prior to working at K&A.
Lehi Pedestrian Bridge Over SR-92
This pedestrian structure is constructed in the rapidly growing section of Lehi. The 2-girder system with concrete deck also includes a custom aesthetic railing. The structure also has switchbacks at the end of the structure to tie into the existing grading.
300 N Pedestrian Bridge Over UTA
This project with UTA had very specific architectural and aesthetic requirements that were coordinated with the client. The final structure included an elevator shaft and steel staircase. A custom snow melt system is built into the structure to reduce maintenance during the winter months.
Provo Intermodal Center OVer UTA
This 155 ft prefabricated steel truss spans over the UTA and UPRR tracks in Provo, Utah. This bridge provides a safer and shorter crossing for pedestrians accessing the FrontRunner station. The bridge structure was designed to tie into a masonry elevator shaft and steel frame stairway.
Temple Springs Trail Pedestrian Bridge
The completion of this bridge provides a connection between Red Hills Parkway to St. George Blvd. in St. George, Utah. The bridge span was set to span over the sensitive wetland area and to protect the existing environment. Trail design also preserved existing red sandstone cliffs and included natural stone retaining walls to blend in with the surrounding scenery.
Coyote Wash Pedestrian Bridge
This structure had strict scour design requirements that required drilled shafts for the foundation. The bridge is adjacent to an existing vehicle bridge and the bridge's wingwalls are designed to tie into the existing structure.
Jeremy Ranch Frontage Road Underpass
Two box culverts were constructed to provide under crossings for the Millennium Trail under the I-80 on/off ramps. This extension of the Millennium Trail now connects it with the Rasmussen Trail and allows users to cross I-80 without interacting with I-80 traffic. The structure design included custom approach slabs to improve ride quality and reduce maintenance costs.
Pedestrian Bridge Over 6200 South
This pedestrian crossing over 6200 South was completed as part of the Bangerter 3 Interchanges project. The structure design included ramps, substructure, and fence design. Coordination was required with the elementary school to provide easy access for students to cross the bridge.
