Upon landing at Pittsburgh International Airport Runway 10C/28C was closed with no lighted X's and there were planes parked all over it. I saw a bulletin come out about overflow aircraft parking. It appears Pittsburgh has a lot of ramp space closed and vacant for a construction project they are not doing. I feel like they could use this space rather than creating a situation for an accident on the airfield.
Air carrier Captain reported Runway 10C/28C is closed at PIT; but not marked with lighted X symbols.
