Republican Rep. Michele Bachmann proposed a bill Tuesday that would build a four-lane bridge over the St. Croix River, according to MinnPost.
The National Park Service ruled that the bridge would violate the U.S. Wild and Scenic Rivers Act after it was proposed last October, said the Star Tribune.
Democratic Rep. Betty McCollum said she would "do everything in my power" to defeat the $700 million dollar bill, reported the Star Tribune.
The Star Tribune said Bachmann introduced a similar bill the previous year but received no support.
American Rivers named the Lower St. Croix National Scenic Riverway one of America's Most Endangered Rivers, according to MinnPost.
