The cities of Bingen, White Salmon, and Stevenson plan to send a letter to the state expressing concern about the number of semi-trucks traveling Highway 14.  The cities say the trucks go through the Gorge on Highway 14 to avoid Oregon taxes on Intestate 84, but don’t buy gas on the Washington side to help pay for their road use.  Bingen Mayor Betty Barnes says the municipalities are asking the Legislature to look at changing how commercial trucks are taxed in Washington, adding there are also safety concerns for the cities where Highway 14 runs right through the downtown area  White Salmon Mayor David Poucher says the cities are asking the state to close the gap in the tax differences that lead to the situation.
