I have been there... Adama Science and Technology University is one of the prestigious universities in Ethiopia
Beautiful view of architectural main gate.
The intrance gate is some times get closed and the exit is used for both ways, so when intering by vehicle you better check if the intrance is open, otherwise enter through the exit gate. The traffic rules shouldn't bother you, its the adama universities norm but be careful of the cars exiting the campus because you are on their way.
