PLT OF A C182 OBSERVED WHAT APPEARED TO BE RAILROAD TIES BLOCKING THE RWY INTXN TO A CLOSED RWY. RPTR BELIEVES THAT OTHER TYPES OF BLOCKING MATERIAL COULD BE USED THAT WOULD NOT CAUSE MAJOR DAMAGE TO AN ACFT WHICH INADVERTENTLY TURNED OFF THE ACTIVE RWY AT THE RWY INTXN.

Narrative

ABE RWY 13/31 CLOSED; PROBABLY FOR RESURFACING. NO APPARENT FAULTS ON ASPHALT SURFACE. THE RWY NOTAMED OTS; BIG YELLOW 'X' ON OVERRUN AREA; LOC SHUT DOWN; AND IT WAS ON ATIS. HOWEVER; ACCESS TO THE RWY; WHERE IT INTERSECTS RWY 6/24 WAS BLOCKED WITH RAILROAD TIES; WOODEN LOGS OF SQUARE CROSS SECTION 12 INCHES BY 12 INCHES. NOW; IF FOR ANY REASON A PLT WAS FORCED TO USE THE RWY; SAY AN ENG- OUT; THE BARRICADES GUARANTEE A MAJOR INCIDENT. EVERYTHING ELSE ON THE ARPT IS DESIGNED TO BE FRANGIBLE - - JUST IN CASE. SO WHY INSTALL TANK-TRAPS? CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT HE OBSERVED THE RAILROAD TIE TYPE BARRICADE AS HE PASSED THE RWY INTXN DURING LNDG AND TKOF AND THOUGHT IT UNUSUAL THAT THE TYPE OF MATERIAL WOULD BE USED FOR A CLOSED RWY. HE DID NOT NOTICE ANY OTHER SIGNS; FLASHING LIGHTS; MARKINGS OR CONSTRUCTION EQUIP IN THE RWY INTXN AREA. HE DID REITERATE THAT THERE WERE APPROPRIATE OTHER MARKINGS AND NOTICES FOR THE CLOSED RWY. HE ONLY FELT THAT THE RAILROAD TIES WOULD CAUSE MAJOR DAMAGE IF INADVERTENTLY RUN INTO BY AN ACFT.
