Throughout the country, many states are debating whether to increase their respective gas tax to shore up roads, bridges, tunnels and other state-operated transportation systems.

Since 2015, sixteen states and the District of Columbia have enacted legislation to increase taxes on gas that help support infrastructure programs. According to the American Road and Transportation Builders Association, voters approved 269 of the 361 transportation funding measures that appeared on township, city, county or state ballots in 2016. Many of these initiatives were approved in Democratic and Republican-dominated regions of the country. Furthermore, Louisiana, Minnesota, Oklahoma and Oregon have transportation funding measures pending in their respective legislatures.
