BENEDICTA – Gov. Paul LePage is refusing to allow road signs to be installed for a new national monument, so supporters of the park are taking matters into their own hands.

Fans of Katahdin Woods and Waters National Monument hung a banner advertising the park from a highway overpass above Interstate 95. The sign appears to be written on a bed sheet or piece of canvas. It says “KWW Exit 264” and was first seen Wednesday.

LePage has long opposed the creation of the monument. President Obama created the park last year.

A governor’s spokesman says it would be “imprudent and premature” to install signs before completion of a 120-day review period ordered by President Trump last month.

The park is 137 square miles near Mount Katahdin.
