Fredericksburg to Biloxi Road Trip: Scenic Drive Guide

This route follows US-290 E and I-10 E, crossing the Colorado River at Columbus, TX. The entire drive covers approximately 560 miles (900 km) and takes about 8.5 hours of pure driving time. A peculiar fact: near the Texas-Louisiana border, the highway runs along the exact 30th parallel north, a line that historically defined Spanish and French territorial claims.

The primary arterials are US-290 E from Fredericksburg to Austin, then I-35 S to San Antonio, and finally I-10 E all the way to Biloxi. Traffic spikes near San Antonio and Houston; avoid these between 7–9 AM and 4–7 PM.
