Narrative: I was taxiing for takeoff on RWY 3L.  Multiple taxiways were closed; and I was not familiar with the airport.  Prior to landing at the airport earlier in the day I retrieved and read the NOTAMs that described the multiple taxiway and runway closures.  I determined that the best course of action would be to request assistance from Ground for all taxi operations.  Therefore I requested 'progressive' taxi instructions of the Ground controller after I started the engine on the GA ramp.  The ground controller instructed me 'Taxi A to 3L; cross 30'.  Runway 30 was closed.  Following the instructions I entered Taxiway A from the GA ramp; crossed RWY 30 at A and continued on Taxiway A.  After crossing RWY 30 the ground controller asked me if I wanted an intersection departure.  I responded 'No' and said I wanted full length (of 3L) 'just in case'.  The ground controller then instructed me to 'Taxi to the end of A'. I continued on Taxiway A with the airport diagram on my yoke mounted iPad and my eyes outside.  As I approached the Taxiway B intersection I saw what looked to me like painted ILS hold lines on Taxiway A ahead of me. There were no signs on either side of the markings to indicate what type of hold line was painted on the taxiway. I continued to taxi at about 10 mph and was almost upon the hold lines when I realized they were runway hold lines!  I immediately applied brakes; but was unable to stop before the nose crossed the hold line.  Note that these hold lines are NOT on the airport plate; nor were signs present to identify them as runway hold lines.  I immediately contacted the Ground Controller and confessed I had crossed a runway hold line.  I offered to return to the ramp to fill out whatever paperwork was necessary.  He told me not to worry and to continue.  At no time prior to this incursion did the Ground controller mention there are multiple runway hold lines on [Taxiway] A; or that a runway hold line was located on [Taxiway] A prior to its intersection with [Taxiway] B; or at any other location on [Taxiway] A.  After being told to proceed by the Ground controller I taxied to the NEXT set of hold lines located prior to the Taxiway A RWY 3L intersection; conducted my runup; contacted the Tower Controller; entered the runway; and departed the airport.  What could be done to prevent a recurrence of this incursion???  I do not know how I could have done anything else; save taxi a lot slower when I see yellow paint markings ahead on a taxiway.  Prior to taxi I realized I needed help so contacted ground control for 'Progressive' instructions.  I taxied at a safe speed that considered I had over a mile to reach the runway.  I attempted to use the most conservative departure strategy with the full runway; and I communicated this clearly to the Ground controller who then directed me to 'taxi to the end of A'.  I saw painted markings on Taxiway A perhaps 200 yards before I reached them.  However; the aircraft had several hundred feet of lateral distance from RWY 3L; and was over 1/4 mile from the Taxiway A/RWY 3L intersection.  Perhaps I should have considered the possibility of a runway hold line very distant from the actual runway; and on a taxiway parallel to the runway; but I've never seen this in my flying experience.  Where such an unusual arrangement of hold lines occurs on a taxiway at a location remote from the runway I believe there should be signage to alert pilots. Regardless; the Ground Controller was advising and guiding my taxi navigation.  In my opinion; he should have alerted me to this unusual situation when I specifically stated that I wanted to use the full length of RWY 3L AND he directed me to continue to the end of Taxiway A.  It's impossible for me to 'trust but verify' when the airport diagram has no plate notes that describe this situation; the Ground Controller fails to alert me to a runway hold line located nearly half mile from the intersection of Taxiway A and RWY 3L; and there are no signs located adjacent t painted taxiway markings to alert pilots of this feature highly unusual feature.




Synopsis: A Cessna 172 pilot was confused by the parallel runway approach area boundary markings on taxiway Alpha; which were a significant distance from the runway in use. As a result; the pilot was unsure if a clearance was required to cross it. When asked; ATC did not explain that holding short was required only when advised.
