Caltrans District 8 will begin a road widening project on State Route 138 in Pinon Hills and Phelan from the Los Angeles County line to west of Phelan Road.

The $4.3 million project will widen the roadway to provide a 14-foot median, wider shoulders and install center rumble strips.

Construction is anticipated to begin this week, with surveying and pavement testing. This project is expected to be completed by Fall 2023. Work hours will be from 8 a.m. to 4 p.m. Mondays-Thursdays, and 8 a.m. until noon on Fridays.

Weekend work may be included to assist in expediting the project, or when weather delays prohibit work during the weekdays.
