What the GTA 4 map covers
Grand Theft Auto IV came out on PlayStation 3 and Xbox 360 in April 2008 and on PC later that year. Its Liberty City is a new, far denser version of the city first seen in GTA III, modelled on New York. The map spans every playable area: Broker and Dukes in the east, Bohan to the north, the long island of Algonquin in the middle, and Alderney, a separate state, across the river to the west, plus the smaller islands in the harbour.
Because the lines come from the game's traffic data, the shape of each borough shows clearly: the tight grid of Algonquin, the curving expressways through Broker and Dukes, the airport approaches in Dukes, and the industrial roads of Alderney. Bridges and tunnels appear as links running across the water between the islands.
How to read the map
The path files contain 25,807 distinct line segments once two-way links are merged, drawn in three colours:
- Pale grey: road links (22,743). Each line joins two nodes that vehicles drive between. Width does not reflect the number of lanes.
- Amber: intersection links (1,843). The short connectors the game uses inside junctions.
- Blue: boat routes (1,221). The paths boats follow on the water. They trace channels and harbours, not the coastline.
The background is plain: there are no buildings, parks or shorelines, because the path files do not store them. Zoom in to follow individual lanes through complex junctions, or move the cursor to read GTA IV world coordinates in the corner of the map.
GTA 4 and the earlier Liberty City
GTA IV rebuilt Liberty City from scratch. The 3D-era city of GTA III and Liberty City Stories has three islands, Portland, Staunton Island and Shoreside Vale. The HD-era city has five boroughs and a street layout much closer to New York's. Comparing the maps shows how far the setting changed between the two eras. For the HD-era city that came after, see our GTA 5 interactive map of Los Santos and Blaine County.
Map data and credits
GTAMap decoded the path network from the game files of a purchased copy of GTA IV (the 2008 PC release) and rendered it as map tiles. The file layout follows the community's documentation of GTA IV's path format, with each record checked for exact sizes and links that resolve. Game data © Rockstar Games / Take-Two Interactive.

GTA 4 map FAQ
Where does this GTA 4 map come from?
It is drawn from GTA IV's own path data: the road-node files in the 2008 PC release (paths.img, 64 node files). We decoded 30,882 nodes and 51,614 link records, all of which resolve, and drew each link as a line in the game's own coordinate system.
Why does the map show lines instead of streets and buildings?
Path data records where traffic and boats can travel, not what the city looks like. Each line is a link between two path nodes, so the map is a network diagram: road widths are illustrative, and there are no building footprints or coastlines. The blue lines are boat routes, not shorelines.
Are the coordinates exact?
Yes, within the precision of the files. The tiles are drawn directly in GTA IV world units with north at the top, so the X/Y readout matches the positions stored in the game with no fitted calibration. Heights are not shown.
Does this map show the GTA IV radar or pause-menu artwork?
No. GTA IV's radar artwork is a separate raster image, and we have not published it here. This page shows the path network only.
Does it cover The Lost and Damned and The Ballad of Gay Tony?
Both episodes take place in the same Liberty City as GTA IV, so the road layout applies to them too. The data itself comes from the original 2008 game files.
