Nothing bad actually happened. All the taxi charts in PUW are currently not accurate. Just as more of a heads up. Taxied to the ramp Via A3; A; D. Lucky weather was good so finding the correct taxiways were easy. But there is little to no guidance that with A4 and closed and the construction maligning getting to the ramp via A1 impassable the only way to access ramp is via A3. Documentation kinda explains the ramp construction; but nothing about to how to get to the ramp with the taxiways closed.Add a taxi diagram with the new A3 and D taxiway and warn crew about if they land [Runway] 5 and exit on A1 their will be no way to the ramp. If a crew lands [Runway] 5 they will need to back taxi to A3 and WSI there. If landing [Runway] 23; A3 is the only way off with A4 closed.
Air carrier Captain reported the taxiways are incorrectly depicted in the charts for PUW airport due the closure of Taxiway A4 and construction activity.
