Travel Interstate 45 South to The Galveston Causeway. Upon entering Galveston, Interstate 45 becomes Broadway. Continue down Broadway til you reach Seawall Boulevard. Turn left onto Seawall. Continue down Seawall until it ends, then turn right on Boddeker Drive. Follow the signs to East Beach.
During special events, the traffic may become slow on Broadway. In that case, take I-45 South and stay in your right lane as you cross the Galveston Causeway. Immediately after you drive to the bottom of the bridge, take the exit ramp that is called the "Harborside Drive & Teichman Road." This will lead you to a stop sign where you need to take a left to Harborside Drive and follow it all the way to Ferry Road. At Ferry Road, take a right that will take you up to the Seawall. When you reach the Seawall, take a left on Seawall and follow the signs to East Beach. This is normally clean sailing to East Beach and can also be used to avoid all of the traffic heading back to Houston!
