Narrative: Taxiing from to Runway 1R.  Initial instructions were to taxi via Alpha; Kilo; Bravo for an aircraft pushed back on Alpha.  After joining Bravo we were instructed to taxi via Echo; Alpha; Alpha One.  This was the first time taxiing to 1R for both of us since the completion of the construction at SFO.  As we joined Alpha One we were presented with the new taxiway layout.  I looked down at the 10-9 chart to determine the taxi route and it appeared that Alpha One continued straight around the end of the runway.  Turns out it does not; and instead makes a 90 degree turn; while proceeding straight puts you on some new taxiway (Lima Two I think).  Just after passing the turn; the captain stopped as we both realized that somehow we weren't on Alpha One anymore; and were going to end up next to an Airbus waiting for a flow time.  We again consulted our charts; only to realize that they were inaccurate since they had not been updated for the construction.  The captain stated he had not seen the signs for the taxiway; but had taxied over a painted sign on the taxiway that indicated the turn for the taxiway; but had assumed the construction crew had made a mistake since the chart showed that we should go straight.  I was head down; looking at the inaccurate 10-9 at the time we approached the sign and never saw this.  After about 30 seconds of us searching for other signs and determining what had gone wrong; ATC asked if we had room to make a 180 and go back to the correct taxiway.  We had room; taxied to 1R and the remainder of the flight was uneventful.The root cause was unfamiliarity with the new taxi route.  Contributing were years of conditioning to the old route; not being provided with up to date aeronautical charts; and NOTAMS that don't provide adequate description of the changes.The route was confusing as the layout was very different from previous; and very different from the depiction on the 10-9.  Our Jeppesen sets were still considered to be current; as the caution date was XX Sep 2014; six days after this event.  However; the 10-9 was from the XY Jul 2014 and had not been updated at all to reflect the new taxiway layout.  The Notices to Airmen were borderline useless.  All they said was that many taxiways including Alpha One had been 'realigned'.  A better description would have been 'Hey; this taxiway now makes a 90 degree turn between the runways; not straight ahead like you'd think when you're not changing taxiways.'  The NOTAM for the taxiway we wound up on simply said it had been 'commissioned'; again making no note of its location or the confusing taxiway designations.First suggestion; get updated 10-9 charts in the Jeppesen sets immediately.  Second; I now realize the chart is available by clicking that exclamation point on my trip sheet; which I did not do because that exclamation point has been there all summer next to any leg involving SFO.  If it's always there; you stop noticing it as it is no longer unusual.  I'm reminded of the parable about the boy who cried wolf.  I didn't even notice it when I checked in for the trip.  I would have guessed it still said the same things it had about us switching terminals and the new parking spots at gate XX.  Something needs to be communicated to crews that the information hidden behind that exclamation point has changed; so take another look at it.     Third; the FAA could write much more descriptive Notices to Airmen.  'Realigned' doesn't really do justice to the changes at SFO; and doesn't help you figure it out when all you have is an inaccurate 10-9 diagram.




Synopsis: A CRJ-700 crew taxiing to SFO Runway 1R missed the turn onto the new Taxiway A1 from Alpha because their Airport Diagram had not been updated but; unbeknown to them; was available at their domicile for SFO trips.
