Narrative:

Due to hazy visibility we flew the lda DME runway 12L approach at stl. On initial contact with the tower we advised that we were parking east cargo. After we landed we turned left on taxiway north, and while the first officer was tuning to the ground frequency, I taxied across runway 13 and onto the cargo ramp before receiving clearance. There was a large number of aircraft operations and ATC was very busy. I was trying to expedite our movement. Runway 13 was not being used for takeoffs or lndgs. Also for the size of airplane I fly it is impossible to clear runway 12L without protruding into runway 13. Unfortunately I let my guard down and made a mistake.
