Dosan Ahn Chang Ho Memorial Interchange (I-10/I-110)

The Dosan Ahn Chang Ho Memorial Interchange (where I-10 meets I-110) is one of the most intense driving environments in Southern California. If you are navigating this junction, you are in the middle of a massive logistics artery. This is a purely transit-heavy zone; there is zero infrastructure here for overnight parking or truck-stop services.

Traffic Flow and Local Landmarks

This is the heart of Downtown Los Angeles. You are navigating the junction of the Santa Monica/San Bernardino Freeway (I-10) and the Harbor Freeway (I-110).

• Conditions: Expect extreme, stop-and-go congestion. The interchange is a complex stack that requires you to be in the correct lane well in advance. Miss a lane, and you will be forced into downtown city streets, which are not designed for heavy commercial traffic.
• Peak Hours: Congestion is severe between 6:30 AM–10:00 AM and 4:00 PM–7:30 PM.
• Pro Tip: Use Go511 to monitor real-time incidents. This interchange is a frequent bottleneck for accidents due to aggressive merging.

Parking Availability & Type

• Official Truck Stops: None. Do not look for them here.
• Unofficial Parking: Avoid entirely. There are no safe, legal wide shoulders or industrial dead-ends near this downtown interchange. Local parking enforcement and LA Department of Transportation (LADOT) are highly active. Street parking in this area is prohibited for commercial vehicles.
• Recommendation: If you need a break, pull off at designated truck stops in the Inland Empire or near the Port of Long Beach well before entering the LA basin.

Fuel Amenities (Diesel Specific)

• High-Speed Pumps: None available.
• Bulk Fueling Discounts: Not applicable in the Downtown core.
• Recommendation: Fuel your rig in Vernon, Commerce, or at the truck stops near the I-10/I-605 or I-10/I-15 interchanges.

Truck-Accessible Dining, Showers, and Driver Comfort

The area is dense with urban development, high-rises, and pedestrian traffic.

• Dining: There are no truck-accessible restaurants within the immediate downtown interchange area. Most establishments are storefronts without semi-truck parking.
• Showers & Laundry: Not available.
• Wi-Fi & Driver Lounges: None.

Turning Radius Alert & Bridge Clearances

• Turning Radius: If you are forced onto surface streets due to a detour, be aware that Downtown LA intersections are tight. Many streets (such as those near the Convention Center) have heavy pedestrian counts and narrow turn lanes.
• Bridge Clearances: While main interstate overpasses meet standard highway clearances (16'+), some local underpasses on surface streets are significantly lower. Always consult the California Legal Truck Access Map if you are navigating off-freeway.

Service, Repair, and Scales

• Nearest CAT Scale: There is no CAT scale in the downtown core. The nearest scales are typically found at larger truck stops in the surrounding industrial zones. Use the CAT Scale Locator to plan your scale-in points before reaching the city center.
• Blue Beacon Truck Wash: None available in Downtown LA.
• Service & Repair: No major heavy-duty facilities exist here. For breakdowns, rely on verified mobile repair networks that operate within the Los Angeles/Long Beach freight corridors.

Ease of Re-entry Score: 1/10

Re-entry is not applicable here. This interchange is for through-traffic or transition between the I-10 and I-110. The stress of the high-speed, multi-lane merges combined with heavy volume makes this one of the most difficult areas to navigate in the country.

Frequently Asked Questions (FAQ)

Can I find a place to do a 30-minute break near the I-10/I-110 interchange?

No. There are no legal, safe locations for a truck to park for a break near this interchange. Keep moving until you reach a dedicated travel center outside of the immediate downtown area.

Is there a low clearance on the I-10/I-110 connector ramps?

No. The main highway connector ramps are built for heavy interstate freight traffic, but always adhere to marked lane signage to avoid getting stuck in a lane that forces you onto local city streets.

Where is the nearest truck repair if I break down in downtown LA?

You will need to call a mobile heavy-duty repair service. Do not attempt to stay on the shoulder of the freeway; the I-10/I-110 junction is extremely dangerous for stopped vehicles.

Where should I fuel before hitting downtown?

Plan your fuel stop in the industrial hubs of the Inland Empire or the suburbs like Ontario or Pomona if you are heading west, or the Long Beach area if coming from the south.
