Narrative:
From cargo ramp on north side controller told us to 'taxi to runway 30L, via taxiway north, hold short of runway 30L.' as we started to cross runway 30R, ground control told us to stop. He then told aircraft on final for runway 12L to 'go around.' all 3 pilots heard and understood the same clearance. Several aircraft we saw all appeared to be on final or dogleg to runway 12R. The controller was working metering, ground and tower frequencys. Supplemental information from acn 523973: controller then told us to taxi to runway 12L. Same controller was working metering, ground and tower concurrently.

Title: CTLR AT STL, WORKING COMBINED FREQS, INADVERTENTLY CLRS A HVY ACR ACROSS A RWY WITH TFC ON FINAL.
Narrative: FROM CARGO RAMP ON NORTH SIDE CTLR TOLD US TO 'TAXI TO RWY 30L, VIA TXWY N, HOLD SHORT OF RWY 30L.' AS WE STARTED TO CROSS RWY 30R, GND CTL TOLD US TO STOP. HE THEN TOLD ACFT ON FINAL FOR RWY 12L TO 'GAR.' ALL 3 PLTS HEARD AND UNDERSTOOD THE SAME CLRNC. SEVERAL ACFT WE SAW ALL APPEARED TO BE ON FINAL OR DOGLEG TO RWY 12R. THE CTLR WAS WORKING METERING, GND AND TWR FREQS. SUPPLEMENTAL INFO FROM ACN 523973: CTLR THEN TOLD US TO TAXI TO RWY 12L. SAME CTLR WAS WORKING METERING, GND AND TWR CONCURRENTLY.
