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.

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.”
