Narrative:

Inadvertently crossed runway 3-21 and unable ground control advisory due to being on tower frequency. On taxiout, 'clrd to runway 11L,' and we missed the sign designating taxiway 4. Cockpit workload with company close-out's weights, cg, etc, definitely a contributing factor. Another contributing factor was unfamiliarity with the tucson airport. We headed for the end of the extension of runway 11L and felt we were clrd to cross runway 3-21 because we were 'clrd to 11L.'
