They do seem to use road and street interchangeably here eg Umm Suqeim St/Rd, as Alison says. Consistency is sorely lacking.
So I would imagine it is just Al Khail Road.
It is the same as All Khail road (the E44) running from Festival City all the way to just past Springs/Meadows area. I go from D71 to D63 on it everyday and have never seen any speed cameras so that rules out a large chunk of it!
If you stay on Al Khail Road (E44) until you get past Business Bay you will see that it turns into Al Khail St according to the signs in the middle of the road. I think it is similar to Jebal Ali vs Jabal Ali and Umm Suqeim Road which turns into Umm Suqeim St and then back into Umm Suqeim Road! :thinking:
