Sen. Alexander: Bill could be 'most important piece of legislation for national parks in decades'

U.S. Sen. Lamar Alexander stands outside the gate to Point Park during a visit on Tuesday, April 3, 2018, in Lookout Mountain, Tenn. Sen. Alexander visited the park to push for a bill that he says will help address maintenance backlogs at federal parks like Point Park.

Sen. Lamar Alexander, R-Tenn., hopes to have the National Park Restoration Act approved this year, saying it could wipe out about $7 billion of backlogged maintenance in the National Parks Service over the next decade.

The senator touted the bill in a visit to Chattanooga on Tuesday morning, where he visited the Point Park branch of Chickamauga and Chattanooga National Military Park, learned local Civil War history and met with local park officials and members of the media.

"This could be the most important piece of legislation for national parks in decades," Alexander said.
