anyone who plans to use business route this weekend better beware, they are closing it during the airshow for an hour or soo, i think it was 2-3?? i forget the time for sure, but i had to use it today and it was closed, i ended up going down off the next exit, taking that for afew miles only to see that it was closed since it went by rt. 60, soo i turned around, went all the way back out, went past the airport and down flaperty run road… if you must go that way, get off at montour run and back road it
