Oak street and Pima in Scottsdale Arizona to Downtown Phoenix. There are lots of variations once you get past AZ51. Oak street will dump you at 3rd street. So moving south ahead of this much better traffic wise. The only high traffic part to the route shown is Mcdowell. Road. I suggest using the 10th street stop light going from north to south if this is a problem. My route uses a right turn and a quick left turn on Mcdowell. This allows you easier access than trying to cross 5 lanes of traffic. As you only need to worry about one side of the traffic flow. by wheel
