The increase in costs is aimed to make up for a $1 billion budget shortfall, according to Washington Senate Democrats.
The bill was one of three passed on Saturday to address the state transportation budget.
“This is a year of budget challenges, but through a spirit of collaboration and compromise, we found a bipartisan solution to keep Washington moving ahead,” said Sen. Marko Liias (D-Edmonds).
Senate Bill 5801 faced some opposition from Senate Republicans.
“We’re putting gas taxes on automatic pilot and we’re putting the citizens of the state on mute,” Sen. Jeff Wilson (R-Longview) said. “Their taxes will keep going up and up, without representation, and the state will keep on taking and taking,” he said.
The Washington State House is also considering a bill to raise the gas tax by nine cents, which is expected to be voted on next week.
