Grand Isle's main street is the seaside start of Louisiana Highway 1 (LA 1), which stretches 436.2 miles (702.0 km) away to the northwest corner of the state, ending near Shreveport. LA 1's automobile causeway at the west end of the island is the only land access to or from Grand Isle. Direct access to Grand Isle's seat of parish government is 95 miles (153 km) away in the more suburban part of Jefferson Parish.
