West Vancouver Freight Access Project

Vancouver, Washington

Start Date: 2012
End Date: May 2013

At the Port of Vancouver USA, Hamilton Construction constructed a pile-supported, water-tight trench that is a critical step toward enabling the port to triple its rail capacity. The "Trench Project" is a first step toward a new dual-use rail line entering the port and crossing underneath the existing BNSF and Union Pacific Railroad's north/south Columbia River Railroad Bridge mainline. This portion of the project involved construction of a retaining wall that allows the new rail line to pass seven feet below river level and installation of 276 battered steel piles to support the track. The most challenging portion of the project involves a section where pile is driven on a four-to-one batter underneath the existing BNSF Bridge with less than a 30-ft. clearance. This is part of a $137 million capital upgrade – the largest in the Port's history.
