A Talk Business-Hendrix College Poll conducted in mid-July found 49.5% of likely Arkansas voters oppose a plan to raise the sales tax to finance construction of a network of four-lane state highways.

The poll found 42% favored the plan, while 8.5% had no opinion.

The 10-year, 0.5% increase in the state sale tax would support $1.3 billion of state bonds for the road network and provide additional funding for county and city roads.

In a March poll by the same group, 50.5% of likely voters were opposed to the sale tax hike.

"Just as was the case the last time we tested voters' opinions, a plurality opposes the notion going into the fall campaign," said Jay Barth, professor of political science at Hendrix College.

The poll surveyed 585 likely voters.
