A courier may enter the Central Business District of a city by any of the streets (at the top of each map) marked 1 through 9 and may leave by any at the bottom similarly labeled.
The courier is to visit each of 7 locations [A-G] in alphabetical order. Only right angled left turns are permitted. No location may be revisited and no part of the route may be re-traversed; the route may be crossed at intersections (two "L" turns are permissible within an intersection).

Offer the shortest route for each of the four maps.
(Inspired by negotiating the prominent one way streets of a major capital city.
I suggest that the user make at least one Print Screen capture of the initial map as locations are added and replaced dynamically on-screen.
