Notre Dame Observation Towers
South Bend, IN United States | 2009
The core of the famous Astoria Column in Astoria, Oregon is made entirely out of a 125 foot spiral staircase of hot-dip galvanized steel.
The column, built to commemorate the end of the Louis and Clark Expedition, was constructed in 1926 and closed in 2007 for safety reasons. Two years later, in a series of eight sections, new stairs were fabricated and installed through the top of the column. Outstanding corrosion protection was required for this project for a long list of reasons: heavy foot traffic, relied upon handrails, and a location a mere 3 miles from the Pacific Ocean being at the top of the list.
Every person going up the tower will see, step on, and hold onto galvanized steel at some point in their journey. Thanks to HDG this attraction is open for visitors once again and will stand as a lasting tribute to the Lewis and Clark Expedition.
