Narrative:
After a takeoff abort, sfo tower advised left turn on next taxiway 'if able,' traffic on final behind was inside of 2 mi, possibly 1 mi. Taxiway nearest on left was not lighted. Rain/night/winds of 50 KTS contributed to difficult taxiing conditions, and marginal taxiing visibility. I turned left onto this nearest taxiway, only to see in my lights numerous, unlighted barricades lying across the taxiway intersection. Evidently the strong winds had blown these barricades down. Also obvious was the flashing units attached to each barricade had expended their power source! No lights or other warning whatsoever (including NOTAMS) indicated a closure at this runway/taxiway intersection (which I presume to be taxiway V). Not even sfo tower was aware of this condition. The frustrating aspect was that the aircraft on final behind us had to fly the missed approach on a night loaded with moderate turbulence, high winds, and numerous windshears. The chart does show a tiny gap in the taxiway depiction at runway 19L/taxiway V. However, the number of operations at sfo which use the taxiway area on an annual basis are relatively rare, rendering this depiction of a taxiway closure a woefully inadequate means of conveying some very valuable information. Callback conversation with tower supervisor revealed the following information: tower supervisor stated the taxiway is a new taxiway but the city has not opened the taxiway because it interferes with the ILS system for runway 19. Taxiway may never be opened.

Title: ACR X ABORTED TKOF MADE TURN ONTO CLOSED TXWY. ACR BEHIND HAD TO MAKE A GAR.
Narrative: AFTER A TKOF ABORT, SFO TWR ADVISED L TURN ON NEXT TXWY 'IF ABLE,' TFC ON FINAL BEHIND WAS INSIDE OF 2 MI, POSSIBLY 1 MI. TXWY NEAREST ON L WAS NOT LIGHTED. RAIN/NIGHT/WINDS OF 50 KTS CONTRIBUTED TO DIFFICULT TAXIING CONDITIONS, AND MARGINAL TAXIING VISIBILITY. I TURNED L ONTO THIS NEAREST TXWY, ONLY TO SEE IN MY LIGHTS NUMEROUS, UNLIGHTED BARRICADES LYING ACROSS THE TXWY INTXN. EVIDENTLY THE STRONG WINDS HAD BLOWN THESE BARRICADES DOWN. ALSO OBVIOUS WAS THE FLASHING UNITS ATTACHED TO EACH BARRICADE HAD EXPENDED THEIR PWR SOURCE! NO LIGHTS OR OTHER WARNING WHATSOEVER (INCLUDING NOTAMS) INDICATED A CLOSURE AT THIS RWY/TXWY INTXN (WHICH I PRESUME TO BE TXWY V). NOT EVEN SFO TWR WAS AWARE OF THIS CONDITION. THE FRUSTRATING ASPECT WAS THAT THE ACFT ON FINAL BEHIND US HAD TO FLY THE MISSED APCH ON A NIGHT LOADED WITH MODERATE TURB, HIGH WINDS, AND NUMEROUS WINDSHEARS. THE CHART DOES SHOW A TINY GAP IN THE TXWY DEPICTION AT RWY 19L/TXWY V. HOWEVER, THE NUMBER OF OPS AT SFO WHICH USE THE TXWY AREA ON AN ANNUAL BASIS ARE RELATIVELY RARE, RENDERING THIS DEPICTION OF A TXWY CLOSURE A WOEFULLY INADEQUATE MEANS OF CONVEYING SOME VERY VALUABLE INFO. CALLBACK CONVERSATION WITH TWR SUPVR REVEALED THE FOLLOWING INFO: TWR SUPVR STATED THE TXWY IS A NEW TXWY BUT THE CITY HAS NOT OPENED THE TXWY BECAUSE IT INTERFERES WITH THE ILS SYS FOR RWY 19. TXWY MAY NEVER BE OPENED.
