Quito is crossed
from north to south by one imaginary urbanization which is
characterized by a new spine: the ¨trolley¨ (Integrated System
of Trolebus Transport) that has modified and activated
the whole communication
system found in the district.
The city, in the last few years, has been subject to a great
urbanization change that extends towards the north, south, the
Valleys of Tumbaco (northeast) and Los Chillos (southeast).
