MADISON, Wis. (AP) _ A proposal that would raise the speed limit on Wisconsin's interstates to 70 miles per hour may run out of gas in the state Senate.

Republican Senate Majority Leader Scott Fitzgerald tells The Associated Press that the bill does not currently have enough support to pass. It takes 17 votes to pass in the Senate.

Fitzgerald said Friday that work continues behind the scenes to address concerns about the bill, and it may still come up for a vote next year.

The Assembly passed the measure in October on a 63-32 bipartisan vote.

The bill would give the state Department of Transportation six months to change interstate speed limits from 65 to 70. It would also allow for a lower 65 mile per hour speed limit for commercial vehicles.
