Holding point A1 is at the end of 23, so to get to the new hangar, you would get to it from there rather than from the terminal Main apron down past Draken?
Not sure the taxilanes bit is relevant here. The FAA define a taxilane as "Taxilane - The portion of the aircraft parking area used for access between taxi ways and aircraft parking positions. Taxilanes are located outside the movement area. Taxilanes provide access from taxiways (usually an apron taxiway) to airplane parking positions and other terminal areas"
