I was working Controller In Charge position. I saw a Cessna turning off of the runway at the taxiway and turn to the west. Approximately 125 feet East of that; I saw a large box truck turn out of the space between hangar rows and drive onto a taxiway to avoid a vehicle parked at the end of a Hangar row and turn into the space between hangar rows to exit the airport. After Ground Control issued taxi instructions to the Cessna to taxi I asked Ground Control if he saw that box truck at the hangar row. He stood up because he could not see this area from where he was sitting; and said 'no.' The truck caused no safety issue with the Cessna because it turned West. If the Cessna had turned East; they would have been approximately 75 feet apart and facing each other.The Ground Control position has to be moved because it CANNOT SEE THE PORTION OF THE AIRPORT THAT HAS HAD THE MOST TAXIWAY DEVIATIONS IN THE PAST 24 YEARS. This is the fourth time I have reported this problem and it needs to be fixed. Will it actually take two aircraft or vehicles hitting before anything is done? It is not only blocking the Ground Control scan of the taxiway but it also blocks the Local control scan of the runways as has been reported in previous reports.
The Tower Controller in Charge observed a truck entering a taxiway. The Ground Controller did not see the truck. The CIC reports this portion of the airport is blocked from the view of the Local and Ground controllers.
