This Week Roadwork On I-15 In Hesperia

HESPERIA, CA. (Pain In The Pass) >> The California Department of Transportation (Caltrans) will continue work on a $122 million project to rehabilitate and repave traffic lanes and ramps and upgrade the drainage systems in the center divider on Interstate 15 in San Bernardino County. This project will not add a extra lane to the freeway or for a train.

The bypass lane will have two lanes to the left and two lanes to the right with a center guardrail around the repaving middle lane. They are repaving that lane for approximately 1 mile at a time. This new traffic pattern will go on for months from around Ranchero Rd. to Highway 395. Expect Major Delays at night and around 4am-5am daily.

  • Highway 395 connector closures could be closed in both directions.
  • In the event of significant rain, NB and SB, lanes #1 and #2 will close due to potential flooding. 

Monday night –  Saturday morning – 2/6-2/11 (Weekend schedule subject to change)

Northbound I-15 from Oak Hill Rd to Main Street – 9pm. to 9am*

  • Alternating lane closures, possibly bringing lanes down to one.
  • All on and off ramps are subject to intermittent closures for crew safety and related roadwork.

Southbound I-15 from Main Street to Oak Hill Rd – 7pm. – 4am*

  • Alternating lane closures, possibly bringing lanes down to one.
  • All on and off ramps are subject to intermittent closures for crew safety and related roadwork.

*Times can subject to change and could go longer or start earlier. On and off ramps may be subject to closure. Please use caution and remember to reduce your speed when approaching and driving through the construction zones. Schedules are subject to change due to inclement weather or construction issues.

Possible onramps and offramps could be closed during paving operation.
