I-26 Construction in Madison County, NC
The bridge is the highest in the state of North Carolina - 220' high, 1000' long, 6 lanes wide (3 north and 3 south).
The hammerhead columns that supported the bridge were hollow with 18" thick concrete and reinforced with steel for support. Three cranes were needed to place each beam - one crane on each end to hold the beam in place and one crane to suspend the steel workers.
A fleet of 12 Caterpillar 789B trucks (200 ton capacity each) were used in hauling excavated material. There are 10 in this picture.
Each of the six tires on each truck were 12' in diameter & the trucks held 1000 gallons of fuel and were fueled twice per day.
Each truck ran two 10 hour shifts per day. They were only shut off 4 hours per day.
This picture shows the Caterpillar 5230. At the operator platform it is 3 stories high, or approximately 30 feet. The 5230 is the largest excavator Caterpillar makes.
This is a side view of the 5230. The bite/scoop contains 26 cubic yards of earth and rock. It takes 3-4 scoops to fill each 200 ton 789B truck.
Bill Maddox (of MFHM), over 6' tall, cannot touch the top of the track on the 5230. Each machine costs about $2.5 million.
