A Colorado proposed ballot measure could designate transportation taxes for only fixing roads and related infrastructure

Colorado voters may soon decide the future of transportation funding in the state.

A proposed ballot measure, known as Initiative 175, would require certain transportation-related taxes and fees to be used only for roads, bridges, safety improvements, and the State Patrol.

Supporters say it’s about fairness. They argue that money generated from vehicles—such as car sales taxes—has been diverted for years, and this measure would ensure those dollars go toward fixing roads and improving infrastructure.

Opponents say the change could come at a cost. The measure would shift roughly 539 million dollars a year away from Colorado’s general fund, which currently pays for things like Medicaid, K-12 schools, and higher education.

Because those programs make up the majority of the state budget, critics warn lawmakers could face tough choices, including possible cuts or the need to find new revenue.

The measure doesn’t require specific cuts, but it would limit the state's flexibility when balancing its budget.

If supporters gather enough signatures, Initiative 175 will appear on the November ballot. If approved, it would take effect in 2027.

For now, the debate highlights a key question for voters: should transportation funding be locked in, or should lawmakers keep the flexibility to decide how state money is spent?
