LANSING, Mich. -

Michigan Gov. Rick Snyder says he's considering other ways to get a new international bridge built across the Detroit River.

The Republican governor told reporters Wednesday that he still hopes the GOP-led House and Senate will approve a new bridge between Detroit and Windsor, Ontario. But he's also looking at an "interlocal agreement" between state government and Canadian officials.

Snyder says a separate bridge is needed even if the owners of the Ambassador Bridge build a second span. They're fighting Snyder's efforts to build a separate bridge.

The Michigan Campaign Finance Network reports the Detroit International Bridge Co. has spent $1.6 million this year on TV ads opposing the new bridge Snyder and Canadian officials support.

It's also pushing a ballot proposal requiring voters' approval to build the alternative bridge.
