Narrative:

Was cleared to taxi from taxiway a short of runway 23L to taxi runway 36 hold short of runway 23R. The same clearance was given to an air carrier B737 and I followed him across runway 23R to hold short of runway 23R on the north side. As I crossed runway 23R tower canceled a takeoff clearance to a saab just taxiing onto runway 23R. This was an unusual routing due to construction. I don't think the clearance was clear.
