Narrative:

Both pilots assumed that takeoff would be on runway 8R. However, we were given a taxi clearance from gate xa to runway 17. No specific txwys were issued with this clearance. On taxiway V, I was 'heads down,' finalizing weight and balance and FMC duties. As the captain made the next left turn and questioned the width of the taxiway, I looked up and realized that we were on taxiway F. I then read him the published 47000 pound weight restr. Our taxi for takeoff continued on taxiway F and taxiway G without incident. Txwys B and B5 should've been used. During a return flight to grr, I noticed that the eastern entrance to taxiway G is marked with a lighted sign 'GA only.' there is no such sign at the entrance to taxiway F.

Narrative: BOTH PLTS ASSUMED THAT TKOF WOULD BE ON RWY 8R. HOWEVER, WE WERE GIVEN A TAXI CLRNC FROM GATE XA TO RWY 17. NO SPECIFIC TXWYS WERE ISSUED WITH THIS CLRNC. ON TXWY V, I WAS 'HEADS DOWN,' FINALIZING WT AND BAL AND FMC DUTIES. AS THE CAPT MADE THE NEXT L TURN AND QUESTIONED THE WIDTH OF THE TXWY, I LOOKED UP AND REALIZED THAT WE WERE ON TXWY F. I THEN READ HIM THE PUBLISHED 47000 LB WT RESTR. OUR TAXI FOR TKOF CONTINUED ON TXWY F AND TXWY G WITHOUT INCIDENT. TXWYS B AND B5 SHOULD'VE BEEN USED. DURING A RETURN FLT TO GRR, I NOTICED THAT THE EASTERN ENTRANCE TO TXWY G IS MARKED WITH A LIGHTED SIGN 'GA ONLY.' THERE IS NO SUCH SIGN AT THE ENTRANCE TO TXWY F.
