JEFFERSON CITY, Mo. (AP) —A penny sales tax that would be dedicated to state and local transportation projects cleared the Missouri House on Tuesday, but it immediately ran into resistance in the Senate.

The state sales tax, which officials estimate could generate nearly $8 billion over a decade, would require voter approval to take effect and would then need to be resubmitted to the ballot every 10 years. Proceeds would fund state highways, local roads and other modes of transportation.

The measure returned to the Senate, where lawmakers approved a similar transportation sales tax earlier this year. But it was being filibustered by Republican senators on Tuesday night.

Both chambers must approve the same plan by Friday for the proposal to make the ballot.

Opponents cited resistance to raising taxes and concern about how the sales tax would affect the poor and older adults.
