ABC Technique Proves to Be as Easy as 1-2-3

Research has shown that ABC techniques expedite construction of bridges through shortened project duration, lower material costs, less personnel and increased safety on the job site. Technology such as Geosynthetic Reinforced Soil-Integrated Bridge Systems (GRS-IBS), Slide-In Bridge Construction (SIBC) and Prefabricated Bridge Elements and Systems (PBES) are major components of these ramped-up techniques.

Innovative Method will Slide in New Fourth Street Bridge in Flagstaff

This is not the first time ADOT has used the bridge slide method to install a new bridge. Last fall, this method was used to install the new Bellemont bridges at I-40 and Hughes Avenue, formerly Transwestern Road, west of Flagstaff. Workers used hydraulic jacks to lift and move the new Bellemont bridges into place after the old ones were demolished. ADOT regularly looks for accelerated bridge construction methods and other innovations that can reduce delays and inconvenience for drivers.

State selects company for $52M College Drive flyover ramp; construction begins early 2021

“Boh Bros. Construction Company’s proposal eliminates the need for an additional structure by realigning existing I-12 westbound traffic to more closely follow the I-12 eastbound alignment and spanning both I-12 eastbound and I-12 westbound with a new I-10 westbound bridge. Westbound traffic will be able to exit to College Drive without crossing through mainline interstate traffic,” DOTD explained in news release. “Additionally, this alignment avoids additional visual and noise impacts to surrounding businesses and neighborhoods during and after construction. Their plan incorporates Accelerated Bridge Construction techniques for demolition and construction of the new bridge, simplifying construction sequencing and maintenance of traffic and resulting in greatly reduced impacts and inconvenience to the public.”

Massive Lifts Help Speed Bridge Construction

A new signature bridge is nearing completion in the city of Irving, just northwest of Dallas. This $39.5-million project spans a tenth of a mile on State Highway 114 and is comprised of five individual bridges, including ramps, that have been connected to the main truss bridge, making it appear as one single structure.

Alexander Street/Road Set to Reopen Friday

Both Mercer County bridges were built with the same roadway configuration as the new D&R Canal Bridge constructed by the NJDOT, and the design of all three bridges is respectful of the historic nature of the D&R Canal and surrounding area, according to the NJDOT. The three bridges were replaced simultaneously, using accelerated bridge construction techniques, which significantly reduced the required closure time of Alexander Street/Road from approximately nine-12 months to less than six months.

All the road construction projects starting in Toronto soon

The City says this construction is the second to last phase of work to rehabilitate the expressway between Jarvis and Cherry Streets and will use an innovated construction technique, accelerated bridge construction, to remove sections of the ramp and replace it with custom built pre-fabricated sections.

Ultra-High-Performance Concrete is Ready to Revolutionize Precast, Prestressed Concrete

Ultra-high-performance concrete (UHPC) is rapidly emerging as a premier material for precast concrete construction. First introduced as “reactive powder concrete” in the early 1990s, this material has seen growing usage in the U.S. and abroad over the past decade. UHPC has been used to construct roadway bridges in France, Japan, and Malaysia; pedestrian bridges in Canada and Venezuela; roof panels and architectural facades in Canada and France; and more.
