Eight miles in length, the "eje" is the main thoroughfare running through León, Guanajuato
. It is an 8-lane monstrosity
with numerous "rotundas" (roundabout
s/traffic circles) at the major intersection
s and is very much in need of redesigning by civil engineer
s, preferably into some sort of limited-access freeway with service drives. It turns into the León-Silao highway at its intersection
with the Periferico (the Mexican city planner's answer to highway loops/spurs).
The speed limit
in the "fast lane" is 80kph, the speed limit
in the left central lane is 60kph and the speed limit
in the right central lane is 50kph. The right lane is reserved for the citywide bus transportation system (i.e. buses are the only vehicles allowed in this lane unless you're planning on making a right turn).
