Why the work is needed?

These full weekend and holiday closures are necessary for worker and public safety during the work. Caltrans will perform major pavement rehabilitation on the two center traffic lanes in both the eastbound and westbound directions of I-80. The roadway has become worn and in need of major repairs due to decades of high traffic use.

Closing I-80 during weekends and holidays instead of 9 months of nightly closures.

These closures will allow for concrete pavement in traffic lanes #2 and #3 to be replaced. These closures will shorten the duration of the project by nine months providing improved safety and better ride quality to the public. These series of weekend and holiday I-80 closures will reduce the number of overnight lane closures needed to complete this work this summer instead of completing in late 2024.
