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 (accessed via Highway 302). 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.
Highway 301 is a short road on St. Thomas, USVI. The purpose of the road is to connect Highway 33 with Highway 30. Currently, if Highway 301 did not exist, travelers would have to travel southeast along Highway 33 to Charlotte Amalie, then back northwest along Highway 30.
Highway 308 (better known as Dronnigens Gade) is a road on St. Thomas, USVI. Branching off from Highway 30 a few miles west of Charlotte Amalie, Highway 308 runs right through the heart of the town, parallel to Highway 30, which runs along the waterfront. Highway 308 passes Highway 40 and Highway 35 along its route, as well as tourist attractions like Fort Christian. The road ends one block east of Highway 35 at Highway 314, which runs south to Highway 30.
Highway 313 is a minor road on St. Thomas, USVI. It is a de facto eastern bypass of Charlotte Amalie. Highway 313 allows travelers on Highway 30 to access Highway 38 (and vice versa) without using the clogged roads of downtown or cutting through a residential area.
