It shows how people used clever solutions to deal with Alaska's challenging natural environment.
Miles Glacier Bridge (Million Dollar Bridge)
The Miles Glacier Bridge is often called the "Million Dollar Bridge" because of its high cost to build. It is located near Cordova in the Valdez-Cordova Census Area. This impressive bridge was completed in 1910. It is a type of bridge called a Pennsylvania through truss, which means the main structure goes above and below the bridge deck. It was added to the National Register of Historic Places in 2000. This bridge was a vital link for the Copper River and Northwestern Railway, helping to transport copper from mines.
Susitna River Bridge
The Susitna River Bridge is another historic railway bridge in Alaska. It is found near Gold Creek in the Matanuska-Susitna Borough. This bridge was built between 1920 and 1921. It is a through truss bridge, similar to the Miles Glacier Bridge, where the train passes through the main framework. It was listed on the National Register of Historic Places in 1977. This bridge was an important part of the Alaska Railroad, connecting different regions and supporting the state's growth.
Grant Street Trestle
The Grant Street Trestle was located in Ketchikan in the Ketchikan Gateway Borough. It was built in 1906 and later updated in 1927. While it was once listed on the National Register of Historic Places, it was removed from the list in 1988 because it was no longer standing. A trestle is a type of bridge that uses a framework of beams to support the track or road above.
