Driving and parking in Galveston
Driving gives you a direct route via I-45, while downtown parking has set boundaries, hours and fees to factor into your plans. The paid district runs from 20th Street to 25th Street and from Harborside Drive to Church Street.

The Splash departs from Gulf Coast Transit District Terminal, 1415 33rd St N, Texas City, and arrives at Galveston Island Transit Terminal, 2418 The Strand, Galveston. This service begins in Texas City, so account for getting to its departure terminal when comparing it with the other options.
