ST. PAUL, Minn. (AP) - Senate Democrats' plan to borrow $1.5 billion for public construction projects has hit a snag.

The public works package calls for overhauls to aging water infrastructure systems, upkeep at college campuses and $400 million for road and bridge repairs. But the so-called bonding bill require a three-fifths majority to pass.

It failed by one vote on a 40-26 vote Thursday. It's unclear when the Senate may try to pass it again.

Republicans repeatedly criticized the package as too large and tried but failed to slim down its size. Republicans who control the House are planning a $600 million so-called bonding bill.
