EL CENTRO–Caltrans construction crews will begin major work Wednesday on a new seven-mile segment of the Interstate 8 Update Project in Imperial County from just west of Ogilby Road to west of State Route 186.

Eastbound and westbound I-8 through Segment 5 of the project will be reduced to one lane in each direction. Speed will be reduced in the work zone.

Traffic flow is expected to slow and motorists are advised to allow additional travel time to reach their destinations.

The I-8 Update is a major pavement rehabilitation project consisting of five segments that will construct Continuously Reinforced Concrete Pavement (CRCP) for more than 48 miles on Interstate 8 in Imperial County.

The work will result in a long-lasting superior roadway, capable of withstanding the heaviest traffic loads. Construction began in 2016 and will be completed by 2019. Two segments have been completed and the final segment will begin work in 2017.
