Clearance heights

How low do Texas bridges go?

About 1 in 8 structures in Texas 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.

FAQ

Texas low clearance questions

Something we missed? Ask a real person who knows bridges.

How many low clearance bridges are in Texas?

Low Clearance Map lists 1,681 low-clearance bridges, tunnels, and overpasses in Texas. 223 of them are lower than 13'6", the height of a standard semi-trailer. Houston, Dallas, and San Antonio have the most low structures.

What is the lowest bridge in Texas?

The lowest road overpass in our database is in Lampasas, at 7'2". Every clearance in our database is checked by a person and tagged with the direction of travel it affects, so you are only warned when it applies to you.

Does Google Maps avoid low bridges in Texas?

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 Texas, 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 Texas?

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 Texas bridge clearance data?

Each of the 1,681 structures in Texas 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.
