Narrative:

I was cleared to taxi by bfi ground control to taxiway B7. Having checked ATIS and due to the taxiway construction that was underway; I understood that B6 was closed; which my only safe route was to use the vehicle access road that is bordered by cyclone fence on the right. I felt there was more than enough room to taxi safely if I stayed to the left edge of the pavement. What I did not know; was that the pavement made a gradual taper that moved my aircraft closer to the fence and made contact with the right wingtip. Upon contact with the fence; the aircraft swung to the right and the propeller struck the fence. I had pulled the mixture off before impact; but propeller was still windmilling. There were 2 people on board -- 1 passenger and myself. There were no injuries. Damage to the aircraft was right plastic wingtip trim; 1 blade of the propeller and some damage to propeller hub. The cyclone fence was pushed in a little where the propeller struck but was not broken. When I went back to take photos; I had a hard time finding impact area. After over 40 yrs of flying and over 3500 hours; I have never even put a scratch on an aircraft. I would suggest that vehicle roadways be marked with 'no taxi area' if they are not to be used and don't assume anything.

Title: A C182 PILOT TAXIED DOWN A ROADWAY AT BFI AND STRUCK A FENCE.

Narrative: I WAS CLRED TO TAXI BY BFI GND CTL TO TXWY B7. HAVING CHKED ATIS AND DUE TO THE TXWY CONSTRUCTION THAT WAS UNDERWAY; I UNDERSTOOD THAT B6 WAS CLOSED; WHICH MY ONLY SAFE RTE WAS TO USE THE VEHICLE ACCESS ROAD THAT IS BORDERED BY CYCLONE FENCE ON THE R. I FELT THERE WAS MORE THAN ENOUGH ROOM TO TAXI SAFELY IF I STAYED TO THE L EDGE OF THE PAVEMENT. WHAT I DID NOT KNOW; WAS THAT THE PAVEMENT MADE A GRADUAL TAPER THAT MOVED MY ACFT CLOSER TO THE FENCE AND MADE CONTACT WITH THE R WINGTIP. UPON CONTACT WITH THE FENCE; THE ACFT SWUNG TO THE R AND THE PROP STRUCK THE FENCE. I HAD PULLED THE MIXTURE OFF BEFORE IMPACT; BUT PROP WAS STILL WINDMILLING. THERE WERE 2 PEOPLE ON BOARD -- 1 PAX AND MYSELF. THERE WERE NO INJURIES. DAMAGE TO THE ACFT WAS R PLASTIC WINGTIP TRIM; 1 BLADE OF THE PROP AND SOME DAMAGE TO PROP HUB. THE CYCLONE FENCE WAS PUSHED IN A LITTLE WHERE THE PROP STRUCK BUT WAS NOT BROKEN. WHEN I WENT BACK TO TAKE PHOTOS; I HAD A HARD TIME FINDING IMPACT AREA. AFTER OVER 40 YRS OF FLYING AND OVER 3500 HRS; I HAVE NEVER EVEN PUT A SCRATCH ON AN ACFT. I WOULD SUGGEST THAT VEHICLE ROADWAYS BE MARKED WITH 'NO TAXI AREA' IF THEY ARE NOT TO BE USED AND DON'T ASSUME ANYTHING.
