Bridges / Special Structures
Speedie & Associates has worked on projects all across Arizona from north to south, east to west. In fact, it's rare when a client inquires about a piece of land we haven't touched in some way since our inception in 1980. We've worked for public and private clients, and our resume of projects is expansive.
Whether it's a major highway project or a small retail building, our experienced staff can provide specific technical expertise to address each project's unique challenges.
Back to Projects Overview
ASU University Dr. Pedestrian Bridge / Plaza
Tempe, Arizona
- This project will construct a pedestrian bridge to span University Drive near the Rural Road intersection, as well as an adjacent urban plaza. The project will increase pedestrian safety and foster connectivity among a major mass transit hub,
- campus facilities and the university's research corridor, including the Interdisciplinary Science and Technology Building (ISTB) 7, on the south side of
- University Drive, and the facilities in the Novus Innovation Corridor on the north side.
68th Street Bridge Reconstruction
Scottsdale, Arizona
- S&A provided geotechnical investigation and construction materials testing and inspection services for the reconstruction of the 68th Street bridge. The majority of the construction work took place in January and February with the demolition and replacement of the main bridge structure. Crews worked around the clock to accomplish this feat in only 28 days. The bridge reopened on May 1, 2019.
Phoenix Sky Train
Phoenix, Arizona
- This project is a 1.92-mile long train that features a transit-oriented design and links passengers between multiple ground transportation modes and the Phoenix Sky Harbor International Airport Terminal. The elevated guideway traverses 3,000 acres of landlocked airfields, terminals, and roadways. The project has three new elevated passenger stations and links the region's 44th Street Valley Metro Light rail station with the airport's economy parking area and Terminal 4. It also includes the world's first transit bridge over an active taxiway which is a three-span, cast-in-place post-tensioned box girder bridge with a 340 FT main span and 90 FT high.
SR 260 - Doubtful Canyon
Gila County, Arizona
- This project involved the widening of SR260 from a two-lane highway to a four-lane divided highway involving several deep rock cuts up to 80 feet in depth and six new bridges at three separate crossing locations. The improvements are along a 3-mile stretch of SR 260 (from east of Kohls Ranch MP269 to Christopher Creek Campground MP272.5 west of Cristopher Creek, Arizona)
US 191 Safford-Springerville
Safford, Arizona
- The work encompasses constructing a new five-span southbound Cold Creek Canyon Bridge on
- new alignment, scour retrofitting the existing northbound Cold Creek Canyon Bridge, and
- replacing the bridge barrier on the southbound Rattlesnake Canyon Bridge. The work also
- includes pavement preservation along both NB and SB throughout the length of the project. Additional work includes constructing retaining wall, replacing guardrail and guardrail end terminals, replacing pavement markings, signing, and other miscellaneous
- work.
Soleri Bridge & Plaza
Scottsdale, Arizona
- Designed by renowned artist Paolo Soleri, the Soleri Bridge & Plaza is "at once a pedestrian passage, solar calendar, and gathering place" along the Scottsdale Waterfront. The bridge is anchored by two 64-foot pylons and is twenty-seven feet wide on the south side narrowing to eighteen feet on the north. The 22,000 square foot plaza includes totemic panels replicating the cast wall motif representative of Cosanti and Arcosanti. Each 3500-pound panel was individually designed by Dr. Soleri with Roger Tomalty and produced at Cosanti in Scottsdale, Arizona.
Pedestrian Bridge | Loop 101 & 63rd Ave
Glendale, Arizona
- The pedestrian and bicycle bridge provides regional connectivity to the Valley's multi-use pathway system from Thunderbird Park in Glendale to Papago Park in Phoenix and beyond. The cable-stay bridge has 20 cables that are each 1 and 3/8 inches thick, holding the bridge in place. The bridge is 260 feet across and weighs approximately 198 tons. The bridge is the first of its kind in Arizona. S&A provided the geotechnical investigation for this project.
Upper Kitty Joe Creek Bridge
Gila County, Arizona
- Design consisted of a new bridge and roadway alignment through difficult terrain and environmentally sensitive areas. This section of S.R. 87 is geologically located in a transition zone. The field geotechnical investigation involved using all-terrain and portable drilling equipment due to site restrictions and environmental issues.
