GTA III's Liberty City: The Three Islands Explained
Portland, Staunton Island, Shoreside Vale — the three islands of GTA III's Liberty City split the campaign into three distinct acts. Here's what defines each.
Grand Theft Auto III's Liberty City is split into three islands, connected by bridges and a subway, and the campaign progresses through them in strict order. You start on Portland, the bridge to Staunton Island opens after a story event, and Shoreside Vale unlocks late in the game. Each island has a distinct neighborhood character, gang affiliation, and visual palette — and the three-island structure is the architectural ancestor of every multi-zone GTA map since.
Below: what defines each island, real-world templates Rockstar drew from, and what's worth doing in each.
Portland Island — the working-class east
The starting island. Heavily inspired by Brooklyn and Queens in early-2000s New York, with bits of Boston's North End in the Italian neighborhood. Densely-built, working-class, gritty. Portland is where Claude starts — at 8-Ball's bomb shop after the bridge collapse — and where the early-game Mafia missions unfold under Salvatore Leone.
Real-world templates:
- Hepburn Heights ↔ housing projects in Brooklyn / The Bronx
- Saint Mark's ↔ Little Italy — Italian neighborhood, Salvatore Leone's territory
- Chinatown ↔ Manhattan's Chinatown — Triad turf
- Atlantic Quays ↔ Brooklyn waterfront — docks
- Portland Beach ↔ Coney Island — boardwalk attempt
- Callahan Bridge ↔ Brooklyn Bridge — the bridge that connects Portland to Staunton
What to do in Portland: the Mafia missions for Salvatore Leone anchor the first act. Save up for a real safehouse before the Staunton bridge opens.
Staunton Island — the urban core
The middle island and the visual centerpiece. Modelled on Manhattan, with skyscrapers, a financial district, an explicit Times Square analog, and the largest concentration of high-end vehicles and weapons in the game. Staunton opens after Salvatore Leone's mission "Salvatore Called a Meeting" and is where the second act unfolds.
Real-world templates:
- Bedford Point ↔ Hell's Kitchen / Midtown West
- Belleville Park ↔ Central Park (in spirit, though scaled down)
- Newport ↔ Battery Park / Lower East Side
- Liberty Campus ↔ Columbia University
- Aspatria ↔ Upper East Side / Park Avenue
- Rockford ↔ Lower Manhattan / Tribeca
The Yakuza operate out of Staunton (Asuka Kasen's villa); the Cartel has presence here too, and the third-act betrayal arc largely plays out across this island.
What to do in Staunton: the Asuka missions are the centerpiece, plus the stadium events (Liberty Memorial Stadium hosts the unlockable side missions).
Shoreside Vale — the suburban frontier
The third and final island, unlocked late in the game. Visually completely different from Portland and Staunton — it's suburban, with detached houses, a lake, an airport, and the dam. Heavily inspired by New Jersey and the suburbs around Newark. Open road, light traffic, much less police pressure than the inner two islands.
Real-world templates:
- Pike Creek ↔ Newark suburban grid
- Cedar Grove ↔ Glen Ridge / Montclair
- Wichita Gardens ↔ Newark housing project
- Francis International Airport ↔ Newark Liberty Airport
- Cochrane Dam ↔ Hoover Dam (visual reference)
The Cartel runs Shoreside Vale; the campaign's final missions take Claude across the dam, into the airport, and back to the Cochrane Dam confrontation that closes the third act.
What to do in Shoreside Vale: the Donald Love missions (which sometimes start in Staunton but resolve here) and the Catalina finale are the must-play sequence.
Travel between them
The three islands are connected by:
- Callahan Bridge (Portland ↔ Staunton)
- Tunnel under the river (Portland ↔ Staunton)
- Lift Bridge (Staunton ↔ Shoreside Vale)
- Subway (Portland ↔ Staunton, hijackable mid-route)
- Helicopter (post-game / mod / cheat)
In a clean playthrough, the bridges open in story order. Bridges are physically locked closed pre-mission and physically open mid-cutscene when the mission unlocks. There's no fast-travel; you drive.
What carried into Vice City and beyond
Vice City (2002) was built on the GTA III engine and shipped with a similar two-island structure (Vice City Beach + Vice City Mainland). San Andreas (2004) scaled the model up to a state with three full cities. Each later GTA's multi-zone structure — Liberty City IV's four boroughs + Alderney, V's Los Santos + Blaine County — traces design lineage to GTA III's three-island template.
