You pay gas taxes to support the roads in Anchorage and elsewhere in the state, as well you should. Think of it as a user fee. Your local property taxes go for Anchorage street maintenance.

The Glenn Highway is used primarily by people in Anchorage and Mat-Su. Why should people in Southeast have to pay for it? Because people in Anchorage pay for roads in Juneau, Ketchikan, and Sitka. We're all in this together. People in other states also pay for our roads, they are 90% federal funded.
