B737 HAS RWY INCURSION AT BWI.

Narrative

WE WERE TAXIING TO RWY 28 FROM GATE X AT BWI. I FOLLOWED TXWY A TO THE INTXN OF TXWYS A AND E. (THERE IS SOME CONSTRUCTION GOING ON NEAR THIS INTXN.) I MADE THE R TURN ONTO TXWY E RATHER THAN CONTINUING ALONG TXWY A TO P1. I THINK THE CONSTRUCTION THREW ME OFF A LITTLE WITH MY TAXIING TO RWY 28. AS WE APCHED THE ACTIVE RWY; I STARTED TO CLR BY LOOKING TO MY L WHERE I NOTICED ANOTHER B737 POSITIONED AT THE END WITH THE LIGHTS ON FOR TKOF. NOTICING THIS I QUERIED MY FO AND STARTED TO BRAKE THE AIRPLANE. AT ABOUT THE SAME TIME THE FO STARTED TO QUERY ME AND GND TOLD US THAT WE NEEDED TO STOP. I STOPPED THE ACFT WITH THE NOSE OVER THE HOLD SHORT LINE ABOUT 10-15 FT. I NOTICED THE ACFT AT THE END HAD EXTINGUISHED HIS LIGHTS. SINCE WE WERE ON GND FREQ I ASSUMED THE TWR HAD CANCELED THEIR TKOF CLRNC. GND CTL INSTRUCTED US TO BACK TAXI DOWN RWY 28 AND EXIT AT THE OFF DUTY RWY 4 TO REJOIN TXWY U TO THE END FOR DEP. ALTHOUGH WE CROSSED THE HOLD SHORT LINE WE STOPPED THE ACFT WELL SHORT OF THE R HAND SIDE OF RWY 28. I THINK THE LOCATION OF THE CONSTRUCTION CAUSED ME SOME CONFUSION. I SHOULD HAVE BEEN MORE AWARE OF MY LOCATION ON THE ARPT. I NEED TO BE MORE VIGILANT WHEN I TAXI AT BWI ESPECIALLY WITH ALL OF THE CONSTRUCTION GOING ON AT THE ARPT. I SHOULD HAVE BEEN REFING THE 10-7 PAGE THE MOMENT THAT THINGS DID NOT LOOK FAMILIAR TO ME. I NEED TO BRING MY AWARENESS LEVEL UP A NOTCH. THE REMAINDER OF THE FLT TO JAN WAS OPS NORMAL.
