Heavy Duty Towing in Diamond Bar, CA

Heavy Duty Towing in Diamond Bar is mostly about one place: the junction of State Route 57 and State Route 60. Diamond Bar is a Los Angeles County city of 55,072 people (2020 census) at 696 feet, incorporated on April 18, 1989. It lies about 27 miles east of downtown Los Angeles. Dispatch answers 24/7. We recover semis, buses, box trucks and equipment around the interchange and the canyon.

The 57/60 confluence

The city is at the junction of the Pomona and Orange freeways. Near the canyon rim, SR 57 meets SR 60 and the two share a short overlap. Heading north after the split, SR 57 ascends slightly, slopes through the edge of the Puente Hills and enters the west end of the Pomona Valley. Exit numbers in the overlap follow SR 60, including the Grand Avenue exit. SR 60 also runs through the city, and I-10 is just north. SR 71 is just east. Tell us which freeway you are on, not which one you were on a mile ago.

Traffic counts

Wikipedia reports that in 2013 the annual average daily traffic on SR 57 was 129,000 between SR 60 and Sunset Crossing Road. The SR 57/SR 60 Interchange Improvements Project is listed as scheduled from 2023 to 2028. A disabled truck in this area is on a heavily used road, and construction can narrow the shoulders. If you are in a work zone, say so.

Brea Canyon to the south

South of the junction, SR 57 drops through Brea Canyon, the gap between the Chino Hills and Puente Hills, a section that opened on March 13, 1972. Diamond Bar Boulevard runs along the valley floor that becomes Brea Canyon. Grades are where brake trouble shows up. A truck that overheated its brakes on a downhill needs the right approach, and we ask whether it has air or smells hot before anyone gets close.

Major local streets

Besides the freeways, the main thoroughfares are Grand Avenue, Diamond Bar Boulevard, Pathfinder Road, Golden Springs Drive and Brea Canyon Road. Chino Hills lies directly east, and Brea and La Habra are to the south in Orange County. That puts several county and city lines close together, so a precise location matters.

Offices, not warehouses

This is not a warehouse town. The South Coast Air Quality Management District was the top employer with 786 workers in the city's 2012 financial report, followed by Walnut Valley Unified School District with 520. Our calls here are more likely to be buses, delivery trucks, moving vans, RVs and freeway breakdowns from drivers passing through.

Faults and shaking

Diamond Bar lies roughly between the ends of the Chino Fault and the Whittier Fault, both part of the Elsinore Fault Zone. After an earthquake, roads and ramps may be closed or damaged. If you are stranded after a quake, call emergency services first.
