Missouri Governor. Mike Parson is proposing to borrow $351 million to repair 250 bridges around the state and free up money for more road repairs. The bridge bonding program is part of Parson’s budget outlined Wednesday in his first State of the State address. The plan comes after voters last November defeated a proposed 10-cent-a-gallon gas tax increase to fund roads and bridges. Parson is proposing to pay off the bonds with general revenues over 15 years. All the bridges already are in the state’s five-year construction program. That means the bonds would free up existing highway funds to be used for other projects. The Republican governor also is proposing to use $50 million in state funds for a cost-share program for local road projects that would provide economic benefits.
