A proposal to raise the state's gasoline tax as a way to improve Michigan's roads and bridges has stalled in the Senate.

According to NBC 25, senators broke early this morning (6/12) after a marathon session without passing a measure that would more than double the 19 cents a gallon tax within five years. The Senate also couldn't come to an agreement to switch from a flat per-gallon tax to one that would fluctuate with price to keep pace with inflationary construction costs.

Senators are expected to revisit the issue today, the last day before their summer break. Governor Rick Snyder has asked for at least $1.2 billion a year to fix Michigan roads.
