BRUNSWICK — It didn’t take long for the old Brunswick Naval Air Station sign to come down and a new Brunswick Landing sign to go up at the main entrance to the former base in Brunswick.

The air station held a closing ceremony on Tuesday the end of its 68-year history and leaving its future in the hands of the Midcoast Regional Redevelopment Authority, which is working to fill the space with private-sector companies.

This morning, the familiar Brunswick Naval Air Station sign at the main entrance on Route 24 was taken down. A short time later, it was replaced by one reading Brunswick Landing, the name the base is now going by.
