The fate of the proposed $3.5 billion Columbia River Crossing might come down to Clark County voters in November.

C-Tran, Clark County's transit system, is considering a 0.1 percentage sales tax increase, which would generate $4.5 million a year to pay for operations and maintenance of the light rail line that would cross the proposed bridge.

On Monday, the idea got a big push from the Vancouver City Council, which endorsed the idea of increasing the sales tax.

The CRC project is counting on state and federal funding to build the bridge, but it won't cover the operating expenses of light rail. C-Tran just passed an $8 million tax increase last year, but the agency has said that money won't flow into the CRC project.
