Liberty Memorial Bridge
- Feb 24, 2012
The original Bridge across the Missouri River in Bismarck ND was constructed in 1922 at a cost of $1.374 million. This bridge was christened the Liberty Memorial Bridge in honor of the North Dakota World War I soldiers.
In 2006, work commenced on a replacement bridge. The bridge design incorporates a 10-foot wide pedestrian walkway and five overlooks or concrete walkouts as a tribute to each branch of the military: Army, Navy, Air Force, Marines, and Coast Guard.
In 2008 a new $62 million bridge was opened consisting of 14 spans with 6 piers located in the Missouri River. This new bridge spans 2370 feet and provides a 285 foot of vertical clearance for tall ships. It carries approximately 15000 vehicles per day. Concrete used for the structure included 5000 psi concrete with fly ash in conjunction with epoxy-coated reinforcing steel. Epoxy-coated reinforcing steel (ECR rebar) was used in the deck construction to provide corrosion protection to the reinforcing steel.
