Paving and Guardrail Work on SR-18

Affected routes: RIM OTM Route 6

SAN BERNARDINO – The California Department of Transportation (Caltrans) will begin a project to mill and overlay current pavement and upgrade guardrail on the shoulder of State Route 18 (SR-18) between Old Waterman Canyon Road and State Route 138 (SR-138). The $17 million project was awarded to All American Asphalt. The project is set to begin on Wednesday, May 30, and is expected to be complete in late 2018.

The guardrail work will begin at State Route 138 (SR 138) and move downhill (south). The paving will begin after the guardrail work is completed. One lane will remain open in each direction during work hours. Motorists may expect delays due to one-way traffic control and occasional, short-term, moving lane closures between the hours of 7:00 a.m. and 3:30 p.m. Monday through Friday.

Commercial trucks are encouraged to avoid the area due to reduced lane width. Please consider using State Route 330 (SR-330) as an alternate route during work hours to avoid delays. Other projects will be taking place on SR-330 with summer also so go to under “work alerts” for the latest information and lane closures.

Please be aware of the work and SLOW FOR THE CONE ZONE. Know before you go! To stay on top of roadwork in the Inland Empire go to and sign up for commuter alerts. View traffic conditions at

New Mountain Transit Programs

In an effort to get more locals using Mountain Transit services, Mountain Transit will be mailing large postcards to all local residents in late May with maps of our service and easy instructions on how to ride.

The postcard will also have a limited time coupon good for five free rides on local routes.

In July, Mountain Transit will implement TAKE TRANSIT TUESDAYS. All Mountain Transit Fixed Routes (FR) as well as Off the Mountain (OTM) services will be free on the five Tuesdays in July!

Both of these programs are being provided through a grant coordinated through San Bernardino County Transportation Authority (SBCTA).
