After almost 11 weeks, the old timbre bridge has been totally removed and work has begun on the foundation of the new concrete bridge. The last couple of weeks have been spent drilling the six holes where the concrete CIDH (cast-in-drilled-hole) piles will be constructed. These piles will support the bridge columns and abutments. Some piles go almost 50-feet into the existing ground. As can be seen in the images above, the subcontractor has had to drill thru several feet of solid rock to reach the design elevation for each pile. Drilling work will continue throughout the next few weeks. The project is a little over 20% complete and is estimated to be finished in the fall of this year.
