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.

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.

TDOT Contractor to Begin Bridge Replacement Project on Interstate 24 in Chattanooga, Hamilton County

TDOT contract crews are scheduled to begin a project to replace bridges over and on I-24 near mile marker 183 in Chattanooga, Hamilton County. Originally built in the 1960s, the bridge on Belvoir Avenue over I-24 and the bridges on I-24 over Germantown Road will be replaced in a $32.9-million project using both traditional techniques and an innovative process called Accelerated Bridge Construction (ABC). ABC requires short-term, total road closures to allow crews the space to do their jobs and the freedom to work around the clock. The closures will also allow construction to be completed much quicker.
