Keeping moose off of the highways in zones 9 and 10

Description 

What methods are most efficient for keeping moose off of highways? There are experimental moose fences in the area, but should these be extended to other parts of the region? If fences are extended, are there options that can still allow animals to migrate, such as underground tunnels? When creating more moose fences, it is important to consider the needs of the wildlife, and a study could highlight these needs.
