Narrative:

I taxied the aircraft onto an active runway (runway 24C) at cle; causing another aircraft to execute a go around. The involved parties include the flight crew; cleveland ground control; and tower. Several factors contributed to this occurrence; but ultimately the fault is my own. We contacted ground at spot X and were given the taxi instructions to take taxiway J to taxiway a to taxiway right and hold short of runway 24C at taxiway B. These instructions were not misunderstood and verified via the 10-9 pages. Adjacent to runway 24C; runway 24L is closed and currently under construction. The construction contributed to a loss of positional awareness. I never saw the hold short markings for runway 24C; and didn't realize that I was taxiing onto an active runway until I had already done so. Also; approaching runway 24L; ground control switched us over to tower; who gave the clearance to hold short of runway 24C at runway 6L. This created some confusion as it did not make any sense. I understood the clearance to mean hold short of runway 24C and runway 6C; which was the intended message. The first officer was attempting to verify tower's instructions to us by examining his charts and; as a result; we had 1 less pair of eyes outside of the aircraft. I realized my mistake almost immediately after it occurred. Unfortunately; it was too late at that point to simply stop and hold short of the runway. We immediately informed ATC of the error and expedited our taxi off of the runway.

Title: CL65 FLT CREW TAXIED ONTO ACTIVE RWY AT CLE DURING PERIOD OF RWY CLOSURE.

Narrative: I TAXIED THE ACFT ONTO AN ACTIVE RWY (RWY 24C) AT CLE; CAUSING ANOTHER ACFT TO EXECUTE A GAR. THE INVOLVED PARTIES INCLUDE THE FLT CREW; CLEVELAND GND CTL; AND TWR. SEVERAL FACTORS CONTRIBUTED TO THIS OCCURRENCE; BUT ULTIMATELY THE FAULT IS MY OWN. WE CONTACTED GND AT SPOT X AND WERE GIVEN THE TAXI INSTRUCTIONS TO TAKE TXWY J TO TXWY A TO TXWY R AND HOLD SHORT OF RWY 24C AT TXWY B. THESE INSTRUCTIONS WERE NOT MISUNDERSTOOD AND VERIFIED VIA THE 10-9 PAGES. ADJACENT TO RWY 24C; RWY 24L IS CLOSED AND CURRENTLY UNDER CONSTRUCTION. THE CONSTRUCTION CONTRIBUTED TO A LOSS OF POSITIONAL AWARENESS. I NEVER SAW THE HOLD SHORT MARKINGS FOR RWY 24C; AND DIDN'T REALIZE THAT I WAS TAXIING ONTO AN ACTIVE RWY UNTIL I HAD ALREADY DONE SO. ALSO; APCHING RWY 24L; GND CTL SWITCHED US OVER TO TWR; WHO GAVE THE CLRNC TO HOLD SHORT OF RWY 24C AT RWY 6L. THIS CREATED SOME CONFUSION AS IT DID NOT MAKE ANY SENSE. I UNDERSTOOD THE CLRNC TO MEAN HOLD SHORT OF RWY 24C AND RWY 6C; WHICH WAS THE INTENDED MESSAGE. THE FO WAS ATTEMPTING TO VERIFY TWR'S INSTRUCTIONS TO US BY EXAMINING HIS CHARTS AND; AS A RESULT; WE HAD 1 LESS PAIR OF EYES OUTSIDE OF THE ACFT. I REALIZED MY MISTAKE ALMOST IMMEDIATELY AFTER IT OCCURRED. UNFORTUNATELY; IT WAS TOO LATE AT THAT POINT TO SIMPLY STOP AND HOLD SHORT OF THE RWY. WE IMMEDIATELY INFORMED ATC OF THE ERROR AND EXPEDITED OUR TAXI OFF OF THE RWY.
