For right now the only legal way out of the canyon is to turn north on 715 before the lookout which will take you to the upper and lower res. then you drop into palmer, after that it is all side streets back to Mt. Herman, makes it a boring end to the ride but that is the only option. Be patient, the wheels are in motion but only time will correct this problem, people on this side of town are working hard to make this a wonderful place to ride, also they need volunteers for trail work on the 3rd Tuesday of each month I do believe if your willing.
