1. Prepare jobsite - Complete
A temporary road known as a causeway is constructed from the west river bank out into the water to access the worksite.
2. Construct piers, abutments - Complete
Crews will construct bridge abutments and six piers from west to east across the river. Two piers are inland and four are in the river. Cofferdams, made from steel sheet pile, were driven into the riverbed to create a dry space to work in the river. Steel pile is driven deep into the earth to help form the foundation for the piers. Then piers are constructed inside the cofferdam.
3. Deliver and place beams - Complete
Pre-stressed concrete beams, manufactured in Elk River, Minnesota were delivered one at time on oversized semi trailers to the jobsite. Two large specialized cranes will then lift and place each beam on top of the piers. Survey crews use GPS coordinates to ensure each beam is positioned exactly right.
The last of 46 beams was set into place at 3 p.m. March 15, 2017. Each beam weighs about 110 tons. In all, 7,566 linear feet and 4,280 tons of bridge beam were installed. Thirty of the beams are eight feet tall and 16 beams are five feet tall.
