JEFFERSON CITY, Mo. (AP) — Two Missouri state senators are proposing a 1-cent sales tax for 10 years to pay for transportation needs.

The proposed sales tax increase was introduced Tuesday in the Senate. It would require voter approval to enact and to continue after 10 years.

Republican Mike Kehoe, of Jefferson City, and Democrat Ryan McKenna, of Crystal City, trumpeted the idea during a news conference along U.S. Highway 50 several miles east of the state Capitol. They were joined by Republican House supporters Dave Hinson, of St. Clair, and Dave Schatz, of Sullivan.

Kehoe says a dedicated transportation sales tax would help fill a hole in Missouri's infrastructure funding.

Missouri transportation officials have said funding for construction and improvements fell from $1.2 billion to less than $700 million during the past year.
