Caltrans says innovative ‘accelerated bridge construction’ method is faster, safer

Caltrans shut down Highway 99 from 47th Avenue to the Highway 50 connector for four days starting Friday to replace the bridge deck at the 21st Avenue Undercrossing. While the project is having major traffic impacts on the Sacramento region, the agency says crews are using innovative accelerated bridge construction techniques to complete the work as quickly as possible. They said the techniques avoid extensive traffic shifts and lane reductions that could last up to six months.
