CHEYENNE, Wyo. (AP) — It now costs more to fill up in Wyoming.

The state fuel tax went up 10 cents a gallon starting Monday despite encountering stiff legislative opposition.

State officials have said the increase will raise about $70 million a year with about two-thirds going to the Wyoming Department of Transportation and the rest going to cities and counties. The increase will see the tax on a gallon of gasoline or diesel fuel rise from 14 cents to 24 cents a gallon.

Proponents of the tax increase argued during this year's legislative session that the regional nature of the gasoline market means that Wyoming residents have in effect been paying more to cover the cost of higher fuel taxes in neighboring states in recent years and that the increase won't result in a 10-cent per gallon increase in prices that Wyoming motorists pay at the pump.
