Narrative:

Taxiing for takeoff on runway 14 at srq. Cleared to taxi to runway 14 and hold short. While taxiing; I inadvertently crossed the hold short line. An aircraft on final may have had to go around. I believe I mistook the runway entrance marking for an ILS hold short line because of where it was on the taxiway. The runway entrance is on the parallel taxiway; facing a 10 foot high brick wall. Mentally; I did not expect the entrance to be there; and I was actually looking past the entrance line to try and find the runway entrance line at a point 90 degrees to the runway; like at most airports. After ground advised me to taxi back; I realized my mistake. I think this has potential to be a recurring problem as the placement is non-standard. I fly to many airports each month; am highly experienced; and still this fooled me. Workload was low. The taxiway is so wide; when I went back I noticed the runway entrance markers on the sides of the runway were blocked by my canopy post as I got close. Pilots do not expect the runway entrance to be on a parallel taxiway; facing a brick wall.

Title: PA34 PILOT REPORTS RWY INCURSION AT SRQ AFTER INADVERTENTLY CROSSING HOLD LINE FOR RWY 14 LOCATED ON TXWY A.

Narrative: TAXIING FOR TKOF ON RWY 14 AT SRQ. CLRED TO TAXI TO RWY 14 AND HOLD SHORT. WHILE TAXIING; I INADVERTENTLY CROSSED THE HOLD SHORT LINE. AN ACFT ON FINAL MAY HAVE HAD TO GO AROUND. I BELIEVE I MISTOOK THE RWY ENTRANCE MARKING FOR AN ILS HOLD SHORT LINE BECAUSE OF WHERE IT WAS ON THE TXWY. THE RWY ENTRANCE IS ON THE PARALLEL TXWY; FACING A 10 FOOT HIGH BRICK WALL. MENTALLY; I DID NOT EXPECT THE ENTRANCE TO BE THERE; AND I WAS ACTUALLY LOOKING PAST THE ENTRANCE LINE TO TRY AND FIND THE RWY ENTRANCE LINE AT A POINT 90 DEGS TO THE RWY; LIKE AT MOST ARPTS. AFTER GND ADVISED ME TO TAXI BACK; I REALIZED MY MISTAKE. I THINK THIS HAS POTENTIAL TO BE A RECURRING PROB AS THE PLACEMENT IS NON-STANDARD. I FLY TO MANY ARPTS EACH MONTH; AM HIGHLY EXPERIENCED; AND STILL THIS FOOLED ME. WORKLOAD WAS LOW. THE TXWY IS SO WIDE; WHEN I WENT BACK I NOTICED THE RWY ENTRANCE MARKERS ON THE SIDES OF THE RWY WERE BLOCKED BY MY CANOPY POST AS I GOT CLOSE. PLTS DO NOT EXPECT THE RWY ENTRANCE TO BE ON A PARALLEL TXWY; FACING A BRICK WALL.
