(AP) — Michigan lawmakers are working on a $1.2 billion road-funding deal that could include a boost in fuel tax and vehicle along with shifting money from other spending priorities.

Majority House Republicans are optimistic a plan can be approved by week's end. But cobbling enough votes for higher gasoline taxes will be difficult.

The goal is passing legislation the Senate and Gov. Rick Snyder can enact without changes. The House returns Tuesday after a month-long break and is in session through Thursday.

Legislators are eying a compromise under which $600 million in additional revenue would be collected from increased fuel and registration taxes. Another $600 million would come from redirecting existing general funds. Specifics have not been finalized.

In May, voters rejected a road-funding plan that included a sales tax increase.
