It's official: The New York State Thruway Authority has chosen a $3.14-billion bid by Tappan Zee Constructors as the plan for the next version of the 3.1-mile-long, 57-year-old Tappan Zee bridge.
When the Utah Dept. of Transportation launched, in 2000, its $1.5-billion project to widen Interstate 15 through Salt Lake City, the agency opted for a delivery method called design-build, which was relatively rare at the time.
