The only problem with this route is the narrow streets and one way streets on 78th Ave,73rd Place, 79th st, 85th St in Glendale/Middle Village.
If you look at google maps street view, there is no way to make a turn from cooper ave onto 79th st due to the underpass.
I love the idea, the only thing i would do is straighten the route and have it run along 80th st from Myrtle ave to Juniper Valley Rd
