The East Beach Freeway Extension begins at an interchange with the Los Santos Freeway near Downtown Los Santos. After meeting the Los Santos Freeway, the East Beach Freeway Extension enters a depressed road cut and travels below street level where it goes until it reaches East Beach. In between these two places, the highway has three partial exits and it also crosses under the tracks of the Brown Streak Railroad. Near Grove Street, the highway raises slightly to cross over an open drainage system before heading ending in the neighborhood of East Beach.
