Narrative:

Was instructed to 'taxi to runway 9, taxiway K, taxiway west, taxiway south, hold short runway 4L. While taxiing to runway 9 on taxiway west, we entered the stop-way for runway 22R, which we should have held short of. On airport diagram it was depicted in white as runway 22R stop-way not in black as runway. It was controller's intention to have us hold short. We didn't realize until we entered but by then too late. This was last leg of 5 days on 27.5 hours. Delays all day. Low time first officer with 40 hours in type. Busy airport.
