Narrative:

After landing on runway 32, tower controller cleared us to turn left on taxiway a, to hold short of runway 22. Although the first officer later recalled hearing and reading back these instructions, both the clearance and the acknowledgement somehow escaped my attention, and he failed to ensure that I was 'in the loop.' during subsequent taxi, completion of after landing checklist, and other distrs, we became focused on our taxi route, which was complicated by the partial closure of taxiway a and several lighted barricades associated with this. In the course of negotiating this 'obstacle course,' and without further communication from the first officer or the tower controller, I proceeded across runway 22 without clearance, as another aircraft (commuter, type unknown) was landing on that runway. Although collision was not imminent and evasive action not required, it was luck alone which prevented this (or much worse) from occurring.

Title: FLC OF AN LGT ACR ACFT INADVERTENTLY TAXIED ACROSS AN ACTIVE RWY WHILE ANOTHER ACFT WAS LNDG, DUE TO COMPLETING AFTER LNDG CHKLIST AND COMPLEX RTE DUE TO CONSTRUCTION REROUTING.

Narrative: AFTER LNDG ON RWY 32, TWR CTLR CLRED US TO TURN L ON TXWY A, TO HOLD SHORT OF RWY 22. ALTHOUGH THE FO LATER RECALLED HEARING AND READING BACK THESE INSTRUCTIONS, BOTH THE CLRNC AND THE ACKNOWLEDGEMENT SOMEHOW ESCAPED MY ATTN, AND HE FAILED TO ENSURE THAT I WAS 'IN THE LOOP.' DURING SUBSEQUENT TAXI, COMPLETION OF AFTER LNDG CHKLIST, AND OTHER DISTRS, WE BECAME FOCUSED ON OUR TAXI RTE, WHICH WAS COMPLICATED BY THE PARTIAL CLOSURE OF TXWY A AND SEVERAL LIGHTED BARRICADES ASSOCIATED WITH THIS. IN THE COURSE OF NEGOTIATING THIS 'OBSTACLE COURSE,' AND WITHOUT FURTHER COM FROM THE FO OR THE TWR CTLR, I PROCEEDED ACROSS RWY 22 WITHOUT CLRNC, AS ANOTHER ACFT (COMMUTER, TYPE UNKNOWN) WAS LNDG ON THAT RWY. ALTHOUGH COLLISION WAS NOT IMMINENT AND EVASIVE ACTION NOT REQUIRED, IT WAS LUCK ALONE WHICH PREVENTED THIS (OR MUCH WORSE) FROM OCCURRING.
