Funding the state transportation system using climate commitment act revenues.

HB 1324 redirects revenues from Washington's Climate Commitment Act (CCA) auction system to fund major state transportation projects, including the I-5 Columbia River bridge replacement and the US 395 North Spokane corridor. The bill amends existing law to require that CCA auction proceeds - previously restricted from road projects - be allocated specifically to highway and bridge infrastructure, rather than solely to climate or environmental programs. Key provisions mandate that funds support projects improving freight movement (like the Gateway freight project) and reducing congestion, which the bill states contributes to lower greenhouse gas emissions. This reallocation changes how CCA revenue is spent but does not alter the underlying auction system or funding amounts.
