Caltrans will be closing State Route 99 for 99 hours to replace a bridge deck 21st Avenue in Sacramento. The closure will last from 8 pm Friday, June 11 to 4 am Wednesday, June 16.
Sacramento County — The California Department of Transportation (Caltrans) is scheduled to close northbound and southbound State Route 99 from 47th Avenue to the U.S. Highway 50 Connector.
The closure is necessary for crews to safely replace the bridge deck on SR-99 at 21st Avenue. Caltrans is taking preventative measures to fix California’s aging infrastructure, including extending the service life of this 62-year-old bridge. To avoid extensive traffic shifts and lane reductions that could last up to six months, crews are using innovative accelerated bridge construction techniques to complete the work as quickly as possible. The work is imperative to continue to provide a safe route.
Crews are also closing the mainline westbound Business 80/Capital City Freeway to southbound SR-99, and the westbound and eastbound US-50 connector ramps to southbound SR-99. In addition, the following ramps are scheduled to be closed:

The 21st Avenue Undercrossing was built in 1959 and widened in 1974. There is currently corrosion on the surface deck, concrete spalling, cracks, the joint seals need to be replaced, and the bridge deck has begun to deteriorate due to wear and tear from high traffic volumes, freight movement, weather and age. Caltrans is replacing the bridge deck before emergency operations are necessary.
