This session will showcase two complex construction projects where steel bridges were utilized to delivery successful projects. The first being located in Queens, NY where an interchange with several alignments were built as part of a Design Build Project. The second highlights the use of over 2500 LF of steel prefabricated bridges with steel substructures to create access in and out of the Strip of Las Vegas while being surrounded by a Formula 1 Grand Prix event. The use of steel allowed for a rapid installation and removal with no long term effects and is planned to be used each year the race visits Las Vegas.
