Milton I-89 Design-Build Bridge Replacement

Client: Milton, VT
Collaborators: Tetra Tech and URS
Project Span: 2013-2017


Teamed with Tetra Tech and URS, EIV is the Quality Assurance Manager for this 4 year project in Milton, Vermont. The replacement bridges span 450 feet over the Lamoille River and includes complex phasing to allow 4 lanes of traffic to flow at all times.

EIV has a team of engineers and technicians providing quality assurance site inspection and documentation for this $23M construction project. The project posed unique challenges due to the large waterway below and the discovery of protected mussel species. The new bridge will be a modern continuous steel girder bridge with a 100-year life span.
