LANSING, Mich. -

Opponents will urge a state board to keep two questions off the fall ballot, including a referendum that could restrict future construction of new bridges.

Critics say both proposals, backed by Ambassador Bridge owner Manuel "Matty" Moroun, have flaws that make them ineligible for the Nov. 6 election.

The Board of State Canvassers meets Monday to decide whether to place them on the ballot.

Moroun's businesses have spent millions to collect signatures and get the questions on the ballot.

The second would require a two-thirds vote of the Legislature to raise taxes.

Moroun's Detroit International Bridge Co. is trying to stop construction of a second competing bridge between Detroit and Windsor, Ontario.

Gov. Rick Snyder has struck a deal with Canada to build the span.
