Bridge Widening Project
Client: Richmond, VT
Project Span: 2011-2013
EIV was part of the Harrison & Burrowes Bridge Constructors Inc (H&B) and CHA, Inc. design build project team for this $13.9 million contract. The Richmond US Route 2 Bridge, also known as the Checkered Bridge, was built in 1929 and it is listed on the National Register of Historic Places.
The longest of Vermont’s three remaining Pennsylvania through trusses, the 350-ft, 85-year-old steel span over the Winooski River, was too narrow and in need of a significant structural upgrade. The project team had to keep the original superstructure intact and widen the entire bridge by 12.6 ft. EIV provided the Environmental Compliance Officer role for the project and ensured that work complied with National Historic Preservation Act and the Vermont Agency of Natural Resources’ permit requirements. Despite an earthquake, two 100-year-flood events and a tropical storm during construction, the project was completed on time and within budget. It was also featured in the Engineering News Record, ENR.
