thats not a decommisioned strip. the highway was being widened and that construction work caused ALOT of inconvinience when going up and down to the airport from my place, which happens to be about 2 miles from the crash site.
theres are a few straight stretchs of newly constructed roads in the city which may appear like a runway to a non local operator, but even those are way outside the circling area.
knowing the parttern flown in OPRN by all operators, including CX, BA, Qatar, EY, EK etc. they stay west of the highway, and the track is pretty much parallel to the highway. they start the base turn just abeam where the red line is marked on the map. most operators fly a teardrop when flying this circle to land instead of the the 30 degree offset followed by a parallel downwind.
