The new 03/21 is the bright shiny runway on the far left side (close to the mountains):
The old one is the one directly parallel to it which is old and gray looking. It was converted to a taxiway when the new 03/21 opened. The new 03/21 opened in 1998.
The old 03/21 was only 10,433ft. long, made of asphault, was only HIRL (High Intensity Runway Lighting), and either didn't have an ILS at all, or was CAT I.
The new 03/21 is 12,467ft. long (big increase), made of concrete, is HIRL/CL (High Intensity Runway Lighting and Centerline Lighting), and has at least CAT II
17/35 is the one that is goes out into sea (shiny one) which is also CAT II
. It opened in 2001 I believe.
18/36 is the one between 17/35 and the terminal which is the CAT I runway I mentioned earlier.
