Box Culverts to be Installed on Interstate 15 in Fontana



By Staff Reports

(Victor Valley) – The California Department of Transportation (Caltrans) will install two box culverts under Interstate 15 (I-15) as part of the Duncan Canyon Road Interchange Project. The master planned storm drain facility was combined with the Duncan Canyon Road Interchange Project to minimize impacts to motorists on the freeway mainline.

The $3 million project was awarded to SEMA Construction, Inc. in late September 2016. Construction work is scheduled to begin January 9th. Two 55-hour full closures of I-15 will be necessary during the project to complete some of the work. It is anticipated that the two full closures will be conducted on consecutive weekends dependent on weather.

The contractor will install signs on January 5th and 6th to alert motorists of the impending work. The work hours are 7:00 a.m. to 3:30 p.m. Monday through Friday with the majority of the work completed behind concrete barriers.

Some lane closures may be necessary during the project so check traffic conditions on the Caltrans Quick Map at before your commute.

The project is expected to be completed in 2017. Motorists are advised to plan ahead, add extra time to their commute, and consider alternate routes. Know before you go! Stay informed about roadwork in the Inland Empire and go to to sign up for commuter alerts.
