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 project involves building the bridge decks offsite and moving them to their new location in 15 pieces each. The old bridges will each be demolished and the new segments will be hoisted into place to replace them. Each bridge will take a weekend to replace. TxDOT says a traditional bridge replacement project would entail months of long traffic backups. The agency chose ABC to avoid the long-term traffic jams. The project will also make it safer for workers because the road sections being worked on will be closed to traffic.
