Installing Supports for the Cable-Stayed Gordie Howe International Bridge

摘要

The Gordie Howe International Bridge is a planned border crossing spanning the Detroit River, connecting Detroit to Windsor, Ontario, Canada. It is named in honor of Canadian-born ice hockey player Gordie Howe who played much of his professional career in Detroit. The complex cable-stayed design for the bridge calls for a main structural support tower on each side of the Detroit River to support what will be one of the largest bridge structures in North America. These support towers (expected to be more than 700 ft above grade elevation) are founded on Malcolm-installed drilled shaft supports that extend down through various geological soil layers and into the limestone bedrock below. In addition to the main support tower, the cable-stayed bridge is anchored back with a series of back span/anchor piers. Similar to the main support tower, these back span/anchor piers are founded on drilled shafts that extend down into the limestone bedrock below.
