This well-tended street goes... well... nowhere. Perhaps it did once upon a time, but now just ends rather abruptly. But, and this is the thing that gets me... the street is still well maintained! The gardeners are often here, keeping the verge nice and green and making sure the trees and shrubs are well fed and watered. In fact, the gardeners are here so often I choose NOT to hide the cache on the street itself, but rather behind it. So don't search in the greenery.
Perhaps some of our longer-term Abu Dhabi residents might remember when this stretch of road was actually used for something?
