Clearance heights

How low do Oregon bridges go?

About 1 in 3 structures in Oregon is lower than 13'6", the height of a standard semi-trailer. Most RVs, box trucks, and rental moving trucks are between 10 and 13 feet tall, so anything in the red bars is a risk for them too.

Does Google Maps avoid low bridges in Oregon?

No. Google Maps, Apple Maps, and Waze do not check your vehicle height against bridge clearances. Low Clearance Map checks your route against every verified structure in Oregon, then sends the safe route to Google Maps or Apple Maps, or to HeadRoom for voice-guided navigation.

How do I avoid low bridges in Oregon?

Plan your trip in Low Clearance Map with your vehicle height set. It flags every structure that is too low for you in your direction of travel and builds a route around them. Then drive it in HeadRoom, which gives voice guidance on Apple CarPlay and Android Auto and warns you before any low bridge.

How accurate is the Oregon bridge clearance data?

Each of the 246 structures in Oregon was verified by the Low Clearance Map team using public records, imagery, and driver reports, and carries Hazard Headings so alerts only fire for the affected direction of travel. The database was last updated in September 2026.
