Winter Weather Causing Two Lane Bypass Closure Again In Both Directions On I-15 In Hesperia

HESPERIA, CA. (Pain In The Pass) >> The California Department of Transportation (Caltrans) will closed a lane in both directions due to weather on Interstate 15 in Hesperia.

Northbound & Southbound I-15 from Main Street to Ranchero Road in both directions. The fast lane and the #2 lane (Only the Bypass Lane) will be closed until Wednesday night* due to a chance of rain showers and snow.

The main reason of the closure is for safety. Drivers will hydroplane and crash due to flooding in the bypass lane. (https://broadskypartners.com/)

Expect delays in this area due to ONLY two lanes will be open.

*Times can subject to change and could go longer. 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.
