FLC OF ACR LGT ACFT INADVERTENTLY TAKE OFF ON THE WRONG RWY AT SLC; RESULTING IN THE WRONG INITIAL CLB TRACK.

Narrative

AFTER LNDG ON RWY 16R AND A QUICK TURNAROUND; WE TAXIED FOR A RWY 34R DEP. I DID NOT HAVE AN SLC ARPT DIAGRAM BECAUSE IT WAS MISSING FROM MY BINDER. I UTILIZED THE CAPT'S ARPT DIAGRAM PRIOR TO TAXI TO REVIEW THE TAXI RTE AND RWY ORIENTATION. IN RETROSPECT I DIDN'T NOTICE THE COMMON THRESHOLD AT 32/34R AND DIDN'T ANALYZE RWY 32 BECAUSE IT IS NOT AN ACCEPTABLE RWY FOR OUR OP. DURING TAXI I AGREED TO ACCEPT A ROLLING TKOF AND BRIEFED THE DEP PROC PER PROCS. APCHING THE THRESHOLD; I WAS DISTRACTED BY 2 RWY MAINT VEHICLES' LIGHTS. AS THE CAPT STARTED HIS L TURN TO ALIGN THE ACFT FOR TKOF; I NOTICED A DISPARITY BTWN THE HSI HDG AND THE RWY HDG BUG (SET FOR 340). AS I ACCELERATED THE ACFT; I TRIED TO REF THE ARPT DIAGRAM (WHICH I DIDN'T HAVE); FELT UNCERTAIN AND CALLED 'WE ARE ON RWY 32' AS WE PASSED THE NUMBERS ON THE DISPLACED THRESHOLD. SINCE I COULD NOT CONFIRM WE WERE ON THE WRONG RWY; AND RECEIVED NO RESPONSE FROM THE OTHER CREW MEMBERS; I CONTINUED THE TKOF. I NOTED A 3000 FT REMAINING MARKER AS WE PASSED ABOUT 80-100 KTS AND CONTINUED THE TKOF. AFTER LIFTOFF I FLEW HDG 340 AND ONCE SAFELY AIRBORNE WE REALIZED OUR ERROR. CONTRIBUTING FACTORS: FATIGUE EARLY SHOW TIME XX30 AM LCL MEM SHOW TIME; UNRESTFUL NIGHT. FIRST DAY OF TRIP SEQUENCE. I DIDN'T HAVE AN ARPT DIAGRAM (FIRST TIME IN 5 YRS). DISTRACTED BY VEHICLE MAINT LIGHTS NEAR RWY THRESHOLD. I SHOULD HAVE BEEN MORE ASSERTIVE IN ABORTING THE TKOF. INACTIVE RWY WAS LIGHTED FOR MAINT. POOR RWY DESIGN. CORRECTIVE ACTION RECOMMENDED: ISSUE VERBAL WARNING FROM TWR IN TKOF CLRNC. PHYSICALLY CHANGE THIS ARPT CONFIGN. ISSUE WRITTEN WARNING ON DEP PLATE AND THE ARPT DIAGRAM. I NOW HAVE AN ARPT DIAGRAM FOR SLC.
