Narrative:

On taxiing out to runway 4L at btr, I mistakenly crossed runway 4L. I had mistook the hold pad for runway 31. ATC alerted us of the error and reissued revised taxi clearance. Crew was on the last leg of a sequence. Aircraft had an airspeed limitation imposed. We were rushing to get ahead of schedule. I 'knew' where I was going (complacency). Runway 13/31 is the usual runway, but it was closed this day. Slow down! Never assume you 'know.'
