Starts at the intersection of TX332 & Country Road 257 in Surfside, Texas. From there take County Road 257 (also known as the Bluewater Highway ... later changing names to "San Luis Pass Road) as it heads northeast and ends at the Lone Star Flight Museum in Galveston, Texas.
It's a route along the Gulf Coast with beautiful views of the Gulf of Mexico & coastal marsh lands.
Primarily the road is a strait shot along the coast with a few sweeping curves here & there. Just about the half way point you reach the San Lius Pass Toll Bridge ($2) that is not quite a mile long.
Along the route you'll pass through multiple coastal towns & communities. There are small bars & restaurants along the way. Gas up before you get on the Highway; there are few places fuel up until you reach Galveston. Once in Galveston I recommend Casey's Seafood at 3802 Seawall Boulevard, Galveston, TX 77550-8848, (409) 762-9625. My family has been going there for generations.
