The new bridge will be 55m wide, rather than the 30m of the original, to provide more lane and shoulder capacity. The federal government is providing US$250 million and it will be delivered under a design and build package for completion in late 2008. Steel or concrete alternatives will be considered.

Five teams have been chosen to submit proposals and cost estimates:

Ames/Lunda

CS McCrossan

Flatiron Constructors and Johnson Bros

KTM Constructors (JV of Kiewitt/Traylor Bros/Massman)

Walsh Construction/American Bridge
