Team Members

The review and assessment is being performed by nationally and internationally recognized experts in the field of bridges and structures, corrosion control, naval architecture and light rail infrastructure. The professional field of floating bridge expertise and stray current corrosion control on structures is relatively narrow. To that end, each review participant has had limited or no previous involvement with Sound Transit or the East Link Project.
