A coalition of environmental conservation groups has filed a federal challenge to a new high-voltage power line that would run through parkland spanning Pennsylvania and New Jersey, on either side of the Delaware River.

The lawsuit was filed Monday in Washington against the National Park Service. The agency recently approved the Susquehanna-Roseland line, which is slated to run through 16 municipalities in northwestern Jersey, from Berwick, Pa., to Roseland.

The roughly $1 billion project would raise the lines' capacity from 230 kilovolts to 500 kilovolts and raise towers to as high as 190 feet tall. Parties to the lawsuit say it will scar the landscape and have a negative environmental impact.

The Park Service won't comment on pending litigation.
