A surprise under the Snake River posed some challenges for the construction crews on the Snake River Pathway Bridge Project. Progress on the middle in-river pier had been proceeding slowly but steadily since mid-March when crews encountered an obstruction approximately 27 feet underground two weeks ago that prevented the sheet piles for the Pier 2 coffer dam from reaching the necessary depth. The project team of Cannon Builders construction personnel and engineers from Nelson Engineering and Teton County collectively developed a plan to resolve the issue, which involved mobilizing a specialized drilling rig from Salt Lake City to break through the obstruction and allow the piles to be driven to the required depth. Workers have now successfully broken through the problem layer. Work on Pier 3 in the east channel has proceeded relatively smoothly thus far, with the majority of the sheet piles having been installed without incident. However, the issues encountered on Pier 2 have caused the project to fall slightly behind its original schedule, although officials are unsure of just how long.
