I-10/CA-57 Interchange

The interchange of the I-10 and CA-57 is a vital transit corridor located in the San Dimas/Pomona area. This junction connects the San Gabriel Valley to Orange County and the Inland Empire. While it is a high-volume freight route, it lacks dedicated infrastructure for long-haul drivers.

Traffic Flow and Local Landmarks

This interchange is a major transition point for traffic moving between Los Angeles and the Inland Empire.

  • Conditions: Traffic volume is consistently heavy. The transition ramps between the I-10 and CA-57 can be complex, with frequent lane shifts.
  • Landmarks: You are near the Fairplex (LA County Fairgrounds). During major events, local traffic surges, significantly impacting freeway speeds and surface street access.
  • Peak Hours: Expect severe congestion between 6:00 AM–9:30 AM and 3:30 PM–7:00 PM. Monitor Go511 for real-time traffic updates and incident reports.

Parking Availability & Type

There is no professional, overnight truck parking at this interchange.

  • Official Truck Stops: None.
  • Unofficial Parking: Strictly prohibited. Do not attempt to use the wide shoulders of the transition ramps or the industrial dead-ends in the surrounding business parks. Local municipal law enforcement is vigilant about monitoring commercial vehicles.
  • Recommendation: If you are nearing your HOS limit, plan to stop at major travel centers in Ontario or Beaumont to the east, or the industrial hubs of the San Gabriel Valley to the west.

Fuel Amenities (Diesel Specific)

  • High-Speed Pumps: None available at this interchange.
  • Bulk Fueling Discounts: Not applicable.
  • Recommendation: If you require high-speed diesel, plan your stops at dedicated commercial travel centers in the Inland Empire. Do not rely on local retail gas stations near the interchange as they lack the turning radius and pump flow rates for semi-trucks.

Truck-Accessible Dining, Showers, and Driver Comfort

  • Dining: No truck-accessible dining exists at this exit. Most nearby restaurants are within retail centers that are not designed for trailer clearance.
  • Showers & Laundry: Not available.
  • Wi-Fi & Driver Lounges: None.

Turning Radius Alert & Bridge Clearances

  • Turning Radius: Stick to the freeway-to-freeway connectors. If you are forced onto surface streets, exercise extreme caution. Streets near the Fairplex have high volumes of passenger vehicles, and many intersections are not optimized for heavy-vehicle turning.
  • Bridge Clearances: Main interstate connectors meet standard highway clearances (16'+). Within 0.5 miles of the exit, you will pass under local road overpasses; however, you should always consult the California Legal Truck Access Map to confirm height restrictions on any surface street detour.

Service, Repair, and Scales

  • Nearest CAT Scale: There is no public CAT scale at this interchange. Use the CAT Scale Locator to identify scales in the larger Ontario or Riverside industrial corridors.
  • Blue Beacon Truck Wash: None nearby.
  • Weigh Stations: There are no active weigh stations or DOT inspection points at this interchange.
  • Service & Repair: No heavy-duty truck centers are located here. Utilize professional mobile repair services if you experience a breakdown.

Ease of Re-entry Score: 2/10

Re-entry is highly discouraged. This is a transition zone, not a service stop. The dense traffic and lack of facilities make exiting at this point stressful and inefficient for commercial operators.
