A total of 58 projects nationwide are receiving nearly $41 million in “Transit in Parks” grants aimed at improving access for visitors to national parks, forests and wildlife refuges.

The Island Explorer, which also serves communities surrounding Acadia on Mount Desert Island, has carried more Adthan 4 million passengers and eliminated nearly 1.4 million private motor vehicle trips since its inception in 1999.
