The primary route is Interstate 45 South (I-45 S) the entire way from Houston to Galveston. It is a direct, well-maintained highway that runs from central Houston all the way to the Galveston seawall. The cruise terminals are on Harborside Drive just minutes from the I-45 end.
You will pass through Webster, League City, and Texas City before crossing the Galveston Causeway bridge onto the island. All tolls are included in The Houston Taxi flat rate fares.
A pre-booked private taxi is the top choice for cruise passengers. Flat rate locked before travel, flight tracking included, direct to your exact terminal, and no surge pricing on busy Saturdays.
Best budget option for 3 or more passengers flying in together. $50 per person from IAH or HOU to Galveston cruise port. $350 flat for 7–10 passengers.
Available but prices surge 2–3x on cruise Saturdays. No guaranteed flat rate and no flight tracking.
Port parking costs $15–$22 per day. For a 7-night cruise that is $105–$154 in parking alone, often more than a round-trip taxi.
