This behemoth contained more than 75 bridges, including a 6,800-ft crosslake span, and more than 350 lane-miles of roadway rebuilt or repaved, totalling a demand in excess of 7 million man-hours. A design-build project, the 35Express moved through nine cities and two counties. Contractors made more than 2,000 individual traffic design changes in order to maintain a throughway for traffic, while keeping to the construction schedule. One-hundred right-of-way acquisitions were made and 270+ utility conflicts were resolved along the way. The corridor was complete this August after four years of work.
