Forty-four bills to increase transportation funding have been considered in 23 states so far in the 2016 legislative session, according to an updated report from the Transportation Investment Advocacy Center.

Of those considering methods to increase transportation funding, eight states—Alaska, Hawaii, Indiana, Minnesota, Missouri, New Mexico, South Carolina and Vermont —have proposed increasing the state gas tax. Three other states—Kentucky, New Hampshire and Tennessee—have proposed alternative fuel fees. Two states—New Jersey and New Mexico—already have transportation funding-related measures on the Nov. 8 general election ballot.

On Feb. 11 a bill in Rhode Island to charge a user fee on large commercial trucks passed the legislature and is currently pending approval from Gov. Gina Raimondo (D). The legislation, backed by Gov. Raimondo, is expected to generate $1.1 billion over the next 10 years through a combination of commercial truck tolls and bonds in order to improve the state’s bridges.
