Narrative:

We had an early morning start for a five leg day. After landing on the final leg we were exiting runway 19L, I was taking over the airplane to taxi to the gate. I cleared left and the first officer cleared right as we crossed runway 19R. We both are pretty sure we were cleared to cross runway 19R but not with 100 percent certainty. Traffic was light with a flight both in front and back of us on approach. Contributing factors are: end of a long day, trying to keep speed up off the runway for following traffic, and preoccupation on my part about the transition from first officer taxiing to my taking over the controls.
