The road begins as Fortuna Road at a dead end on the westernmost part of St. Thomas. Highway 30 starts out heading northwards, but quickly turns east and runs through the quiet western section of the island. After meeting Highway 301, the road heads in a southeasterly direction, passing the University of the Virgin Islands and Cyril E. King Airport. Soon after the airport, Highway 30 meets Highway 33, a road which serves the northern part of St. Thomas, as well as Highway 308, a road which runs parallel to Highway 30 through the heart of Charlotte Amalie. Highway 30 runs along the Caribbean Sea at this point, and travelers can see the cruise ships docked at Charlotte Amalie's harbor. After leaving the immediate vicinity of Charlotte Amalie and becoming one of the busiest roads on the islands, Highway 30 passes Havensight, a large shopping center. This part of the road is prone to traffic jams, due to a combination of the large amount of shoppers, poorly timed lights, and a complex intersection with Highway 313. After passing Havensight, Highway 30 quickly becomes a residential road, with many houses on either side. Finally, the road meets Highway 32 in the town of Nadir and comes to an end.
