This is a typical intersection in Cortona. The street/ramp running left to right is the more significant one and runs up and down. The streets on either side run with the slope and are, for Cortona, relatively flat. Note though how they transition to meet the very steep ramp: all the grade is taken up within no more than 3 feet. That would be close to not making ADA. Note too how the cross slope matches the ramp grades. The water fountain is a relic from before the common system.
