Corpus Christi to Biloxi Road Trip: Gulf Coast Guide

Driving from Corpus Christi, TX to Biloxi, MS spans 680 miles along the Gulf Coast, primarily via US-90 and I-10. This route traces the path of Hurricane Katrina’s 2005 landfall near Biloxi, a storm that reshaped the coastline and led to massive infrastructure upgrades along I-10. The journey takes roughly 10.5 hours of pure driving, but with stops, it fills two full days.

The most direct route uses I-37 from Corpus Christi to San Antonio, then I-10 east through Houston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, and finally Gulfport to Biloxi. Alternatively, US-90 hugs the coast from Houston to Biloxi, adding 50 miles but offering ocean views. Fuel costs for a 25 mpg car at $3.20/gal run about $87 for the full trip. Toll roads are minimal; only the Westpark Tollway in Houston may apply if used.
