After an ILS approach to runway 13, I landed and requested a progressive taxi. As I continued southeast, ground advised that heavy fog made my aircraft difficult to see. Ground further advised that I should maneuver as necessary to avoid what appeared to be major construction activity and many construction vehicles. To this end, I at one point left the marked taxiway to avoid 2 trucks parked in the middle of it. I regard what happened subsequently as outrageous. After I parked and left my aircraft, I was detained by police officers and members of the national guard. I was told that I had 'broken the red' meaning that I had crossed a thin red line demarking an area around a national guard installation. This detention should never have happened. I was under ground's direction to maneuver off the taxiway to avoid construction equipment and activity. Moreover, and more significant in my view, the thin red line was not adequate to communicate that the area was off limits even to avoid construction equipment and activity. The marking was, for example, non standard. If the area was not to be entered for any purpose, it could have been marked with standard yellow airport markings or, at a minimum, very heavy markings visible in low visibility conditions. Callback conversation with reporter revealed the following information: reporter said that on a clear day none of this would have happened. The normal taxiway was blocked with construction and the non-standard red marking was not clear as to what it was for. He was detained for several hours until an understanding was reached that he was not a threat to the military.

Title: LIMITED GND VISIBILITY, CONSTRUCTION, NON STANDARD SURFACE MARKINGS AND LIMITED FAMILIARITY WITH THE ARPT LED TO INCURSION INTO MIL RAMP SPACE AND DETENTION BY AUTHS.
Narrative: AFTER AN ILS APCH TO RWY 13, I LANDED AND REQUESTED A PROGRESSIVE TAXI. AS I CONTINUED SE, GND ADVISED THAT HVY FOG MADE MY ACFT DIFFICULT TO SEE. GND FURTHER ADVISED THAT I SHOULD MANEUVER AS NECESSARY TO AVOID WHAT APPEARED TO BE MAJOR CONSTRUCTION ACTIVITY AND MANY CONSTRUCTION VEHICLES. TO THIS END, I AT ONE POINT LEFT THE MARKED TXWY TO AVOID 2 TRUCKS PARKED IN THE MIDDLE OF IT. I REGARD WHAT HAPPENED SUBSEQUENTLY AS OUTRAGEOUS. AFTER I PARKED AND LEFT MY ACFT, I WAS DETAINED BY POLICE OFFICERS AND MEMBERS OF THE NATIONAL GUARD. I WAS TOLD THAT I HAD 'BROKEN THE RED' MEANING THAT I HAD CROSSED A THIN RED LINE DEMARKING AN AREA AROUND A NATIONAL GUARD INSTALLATION. THIS DETENTION SHOULD NEVER HAVE HAPPENED. I WAS UNDER GND'S DIRECTION TO MANEUVER OFF THE TXWY TO AVOID CONSTRUCTION EQUIP AND ACTIVITY. MOREOVER, AND MORE SIGNIFICANT IN MY VIEW, THE THIN RED LINE WAS NOT ADEQUATE TO COMMUNICATE THAT THE AREA WAS OFF LIMITS EVEN TO AVOID CONSTRUCTION EQUIP AND ACTIVITY. THE MARKING WAS, FOR EXAMPLE, NON STANDARD. IF THE AREA WAS NOT TO BE ENTERED FOR ANY PURPOSE, IT COULD HAVE BEEN MARKED WITH STANDARD YELLOW ARPT MARKINGS OR, AT A MINIMUM, VERY HVY MARKINGS VISIBLE IN LOW VISIBILITY CONDITIONS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID THAT ON A CLR DAY NONE OF THIS WOULD HAVE HAPPENED. THE NORMAL TXWY WAS BLOCKED WITH CONSTRUCTION AND THE NON-STANDARD RED MARKING WAS NOT CLR AS TO WHAT IT WAS FOR. HE WAS DETAINED FOR SEVERAL HRS UNTIL AN UNDERSTANDING WAS REACHED THAT HE WAS NOT A THREAT TO THE MIL.
