Narrative:

After landing, tower cleared aircraft to taxi to parking. Tower was working both tower and ground control. I entered a taxiway that was not NOTAM'ed, mentioned on ATIS or mentioned by tower/ground -- and only after taxiing several hundred ft found barricaded closed at the entrance to FBO ramp. I attempted to turn onto a short 'stub' taxiway that led to a ramp used by another FBO. As I attempted to complete u-turn from closed taxiway to stub taxiway to ramp, the left main landing gear went into soft turf bordering taxiway. I immediately stopped the aircraft. The flight technician and I got off the aircraft to survey the situation. The aircraft traveled about 2 ft into the soft turf and had sunk about 4-6 inches. I returned to the cockpit and shut down the engines. Our FBO sent a tug out to the aircraft and pushed us back on the taxiway, positioning the aircraft so it could be taxied without further maneuvering. Our flight technician, an a&P/ia inspected the aircraft prior to further flight. The whole incident was over in about 20 mins. The tower complained that the city had closed the taxiway without proper notification, hence no NOTAM, ATIS, etc. The tower also mentioned that several other aircraft had had trouble with the closed taxiway. I don't know the protocol for informing the FAA about airport information, but it seems the right hand is not talking to the left hand. If tower and ground had been operated by separate people, there might have been time to alert us.

Title: CPR JET TAXIES INTO MUD AFTER GOING DOWN POORLY MARKED DEAD-END TXWY AT SYR AND TRIES TO TURN AROUND.

Narrative: AFTER LNDG, TWR CLRED ACFT TO TAXI TO PARKING. TWR WAS WORKING BOTH TWR AND GND CTL. I ENTERED A TXWY THAT WAS NOT NOTAM'ED, MENTIONED ON ATIS OR MENTIONED BY TWR/GND -- AND ONLY AFTER TAXIING SEVERAL HUNDRED FT FOUND BARRICADED CLOSED AT THE ENTRANCE TO FBO RAMP. I ATTEMPTED TO TURN ONTO A SHORT 'STUB' TXWY THAT LED TO A RAMP USED BY ANOTHER FBO. AS I ATTEMPTED TO COMPLETE U-TURN FROM CLOSED TXWY TO STUB TXWY TO RAMP, THE L MAIN LNDG GEAR WENT INTO SOFT TURF BORDERING TXWY. I IMMEDIATELY STOPPED THE ACFT. THE FLT TECHNICIAN AND I GOT OFF THE ACFT TO SURVEY THE SIT. THE ACFT TRAVELED ABOUT 2 FT INTO THE SOFT TURF AND HAD SUNK ABOUT 4-6 INCHES. I RETURNED TO THE COCKPIT AND SHUT DOWN THE ENGS. OUR FBO SENT A TUG OUT TO THE ACFT AND PUSHED US BACK ON THE TXWY, POSITIONING THE ACFT SO IT COULD BE TAXIED WITHOUT FURTHER MANEUVERING. OUR FLT TECHNICIAN, AN A&P/IA INSPECTED THE ACFT PRIOR TO FURTHER FLT. THE WHOLE INCIDENT WAS OVER IN ABOUT 20 MINS. THE TWR COMPLAINED THAT THE CITY HAD CLOSED THE TXWY WITHOUT PROPER NOTIFICATION, HENCE NO NOTAM, ATIS, ETC. THE TWR ALSO MENTIONED THAT SEVERAL OTHER ACFT HAD HAD TROUBLE WITH THE CLOSED TXWY. I DON'T KNOW THE PROTOCOL FOR INFORMING THE FAA ABOUT ARPT INFO, BUT IT SEEMS THE R HAND IS NOT TALKING TO THE L HAND. IF TWR AND GND HAD BEEN OPERATED BY SEPARATE PEOPLE, THERE MIGHT HAVE BEEN TIME TO ALERT US.
