Hesperia, California (Our Hesperia) – The I-15 Southbound Cajon Weigh Station relocation will soon impact Hesperia-area commuters, as Caltrans sets nightly restriction times to support a major safety upgrade at the top of Cajon Pass.

Project Overview: Why the I-15 Southbound Cajon Weigh Station Relocation Matters

The I-15 Southbound Cajon Weigh Station relocation is a significant infrastructure project for Hesperia and the High Desert. Caltrans is moving the current weigh station and truck brake check area to a new, combined facility. This change is designed to improve highway safety, streamline truck inspections, and keep dangerous vehicles off the road. For local drivers and businesses, the project promises smoother commutes and better enforcement of trucking regulations.

Proposed Restriction Times for Hesperia Commuters

Caltrans has announced the following restriction times for the I-15 Southbound Cajon Weigh Station relocation project:

  • Nightly closures from 7:00 p.m. to 5:00 a.m., starting Monday, May 5, 2025, through Saturday, May 17, 2025.
  • During these hours, ramps at Oak Hill Road and connector ramps to Highway 138 will be closed.
  • Only the left lane (Lane #1) will remain open for through traffic.

These closures are necessary for construction crews to safely work on the new site and update the surrounding highway infrastructure. Schedules may change due to weather or construction delays, so drivers should watch for posted signs and updates.

How the Weigh Station Relocation Will Benefit the High Desert

Relocating the weigh station and brake check area is more than just a construction project. It’s a crucial step to:

  • Enhance safety for all drivers by catching unsafe trucks before they reach populated areas.
  • Support law enforcement in enforcing trucking laws.
  • Reduce the risk of accidents and improve traffic flow for daily commuters.
  • Protect local businesses and families by ensuring only safe vehicles travel through the region.

What Hesperia Drivers Need to Know

Expect heavier traffic during restriction times, especially in the evening and early morning. Plan your trips to avoid delays, and follow all detour signs. Truck drivers should be extra cautious and use alternate routes if possible. Caltrans expects the new weigh station and safety area to be completed by summer 2025, weather permitting.

Importance of the I-15 Southbound Cajon Weigh Station Relocation

This project is vital for the future of Hesperia and the High Desert. By investing in safer roads and better enforcement, Caltrans is helping to protect the community and keep commerce moving. The temporary inconvenience will lead to long-term benefits, making the I-15 corridor safer and more efficient for everyone.
