Caltrans completes bridge work on Echo Summit

Construction, which started last spring, included a full closure of U.S. 50 over the summit this September to install seven precast, prestressed 96-foot bridge girders. The full closure was completed five days ahead of schedule and incorporated elements of Caltrans’ accelerated bridge construction approach to complete projects faster and more efficiently.

Nearly $1 million federal grant to help replace bridge

“These grants help state, local and tribal governments deliver projects sooner and more cost-effectively for the traveling public,” Federal Highway Administrator Nicole Nason said. Fulton’s project will make use of prefabricated bridge parts and “Accelerated Bridge Construction” (a catch-all term for a number of methods meant to speed bridge replacement, including advanced pre-planning and more efficient construction methods).

New, Wider Fourth Street Bridge Completed In Flagstaff, Arizona

The Arizona DOT (ADOT) used an innovative accelerated bridge construction method known as the bridge slide to construct the new bridge and complete the project in just over six months. The slide method allowed ADOT to construct the bridges to one side, then slide them into place over one long closure which greatly reduced the impact to the traveling public.

Best Small Project (Under $10 Million): The 54.5 Hour Fix – NB-360 Bridge Rehabilitation Project at MP A58.88

After more than 60 years in service, the aging superstructure of a 90-ft-long bridge that carried Interstate 476 over State Route 309 near Allentown, Pa., had reached the end of its life. The Pennsylvania Turnpike Commission selected an accelerated bridge construction (ABC) delivery method to ensure a swift replacement for a bridge that would carry roughly 30,000 vehicles per day. By using an accelerated method, the team determined that a new bridge could be installed within a 55-hour window over the weekend of Sept. 6-9, 2019. During that window, I-476 and SR 309 would be closed. The project marked the third time the PTC had closed the turnpike to use ABC techniques for bridge replacement.

Bridge Construction on Highway 1 Halfway Completed

Construction crews are nearly halfway complete with bridge construction work on Highway 1 north of Kalona. Beginning August 10, crews were given 45 calendar days to complete the work. Transportation Engineer Manager Lauren Giarmo says crews are implementing an accelerated bridge construction technique to finish the project more quickly than traditional projects.

Texas’ first accelerated bridge construction project set for I-635

Texas will get its first accelerated bridge construction project this month, for one of its busiest highways in the northern part of the state, according to the Texas Department of Transportation. The ABC method, which has been used in recent years around the country to rapidly replace damaged or deteriorated bridges with minimal traffic disruptions, will be employed to replace two 50-year-old bridges on Interstate 635 near its intersection with I-20 and U.S. 275. The area east of Dallas in Balch Springs sees up to 150,000 vehicles a day, according to the TxDOT.

Phase Three Construction on the Newport Pell Bridge Begins Tuesday

Phase Three work on the Newport Pell Bridge is set to begin a month ahead of its expected start date on Tuesday, August 11th, with hydro-demolition and milling work beginning the week of August 17th. The project is expected to last through the end of November. This phase of the project will focus on rehabilitating the eastbound passing lane (center lane on the south side heading to Newport) of the bridge deck, as well as accelerated replacement of an area previously not scheduled for replacement until after completion of the RIDOT Newport Ramp Realignment Project.

High-performance Composites Bridge Offers Cost-effective, Rapid Solution for Rural Tennessee Community

Located one-hour northwest of Knoxville on Elizabeth Church Road, the two-lane bridge has needed repair for many years, Morgan County Highway Superintendent Joe Henry Miller said. Miller and county officials are partnering with private industry and researchers at the University of Tennessee (UT) and the Institute for Advanced Composites Manufacturing Innovation, or IACMI—The Composites Institute®, in Knoxville to create an affordable bridge that can be installed quickly and will safely meet transportation needs in the rural community.

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.
