The specialized freight trucking industry in the United States is a significant economic force, worth over $125 billion annually. This robust sector is experiencing steady growth, driven primarily by nationwide infrastructure projects and the increasing demand for renewable energy transport.
Scale is a defining characteristic of this industry, with more than 10 million oversize/overweight permits issued annually across the country. These permits primarily facilitate the transport of construction equipment, generators, turbines, and agricultural machinery.
Most heavy hauls involve substantial loads weighing between 40,000 to 120,000 pounds and spanning up to 20 feet wide, highlighting the specialized expertise required for safe and efficient transport.
California stands out among the top three states for oversize transport demand, a position attributed to its bustling ports, extensive agricultural operations, and thriving technology manufacturing centers.
Coastal states like California face additional complexity due to environmental protection zones along transport routes, with approximately 15% of heavy hauls involving marine-related industries.
Customer expectations in this specialized industry are clear and demanding. A recent industry survey revealed that 92% of heavy equipment buyers consider on-time delivery and damage-free transport their top priorities.
Our coverage area includes the neighborhoods of Downtown San Dimas, Bonita Park, and the surrounding areas. We're well-equipped to handle logistics needs in this bustling region.
We have direct access to major highways like I-10, I-210, and SR-66, making it easy for us to transport oversized loads throughout the San Gabriel Valley and beyond. We also have routes that connect to Los Angeles International Airport (LAX) and the Port of Long Beach.

All oversize loads entering the City of San Dimas, Los Angeles County, must conform to the requirements set by the California Department of Transportation (Caltrans) and San Dimas Municipal Code.
Generally, any vehicle exceeding 8 feet 6 inches in width, 14 feet in height, or operating with a gross vehicle weight exceeding 80,000 pounds requires an oversize/overweight load permit from Caltrans and potentially the City of San Dimas Public Works Department depending on the route.
Vehicles exceeding 10 feet in width or 15 feet in height often require a route survey within San Dimas to ensure clearance under bridges and overpasses along major thoroughfares like Arrow Highway and Bonita Avenue. Contact the San Dimas Public Works Department for survey requirements.
Escort vehicles are typically required in San Dimas when the load exceeds 12 feet in width, 16 feet in height, or extends more than 10 feet beyond the front or rear of the transporting vehicle. Specific requirements may vary based on the proposed route and time of day.
For loads exceeding 14 feet in width or 18 feet in height, a California Highway Patrol (CHP) escort may be required in addition to private escort vehicles. Contact the CHP Commercial Vehicle Enforcement Unit (CVEU) for scheduling and fee information. Expect to pay approximately $150/hour for CHP escort services, with a 4-hour minimum.
For permits specific to City of San Dimas roads, applications should be submitted to the San Dimas Public Works Department, located at 245 E. Bonita Avenue, San Dimas, CA 91773. Contact them at (909) 394-6260 for specific forms and procedures. Caltrans permits can be obtained online through the Caltrans website.
Required documentation typically includes a detailed description of the load, vehicle specifications, a proposed route map, and proof of insurance. For overweight loads, axle weight certifications may also be necessary. San Dimas may require a certificate of insurance naming the city as additionally insured.
Oversize load movements are generally restricted during peak traffic hours (7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM) on weekdays within San Dimas. Weekend restrictions may also apply, particularly on major holidays.
Seasonal restrictions may be imposed during periods of high fire risk or during special events like the San Dimas Western Days celebration. Check with the Public Works Department for any temporary restrictions in effect.
Certain residential neighborhoods and narrow streets within San Dimas are restricted to oversize loads due to limited access and potential for damage. The Public Works Department will specify approved routes on the permit.
The City of San Dimas charges permit fees based on load size, weight, and the complexity of the route. Caltrans also has its own fee schedule.
Fees may vary depending on the number of days the permit is valid and whether any special accommodations are required, such as temporary lane closures or utility line adjustments.
