A provision of the bill would allow Detroit to spend 20 percent of its portion of the proceeds on transit. Detroit has been funding transit only through its general fund — with no dedicated revenue stream — and it has arguably the worst transit system of any major city in the nation. With the city in bankruptcy, general fund revenues for transit have been in short supply. Riders report two-and-a-half-hour one-way commutes, or buses that never show, making it nearly impossible to hold down a job without a car.

Although the region is in the process of merging Detroit’s transit system with SMART, the suburban transit provider, establishing a seamless system has been fraught with political challenges. Regional planners, for instance, recently shifted millions of dollars in transit funding from Detroit to the suburbs. A new funding source would be huge.

Under the plan approved by the State Senate, Michigan’s gas tax would incrementally rise 17 cents per gallon over the next few years. Raising the tax to fix the state’s roads has been a top priority of Governor Rick Snyder, and Republican lawmakers apparently felt comfortable advancing it following the election.
