Rockingham I-91 Design-Build

Client: Rockingham, VT
Project Span: 2017-2022


This $44.5M bridge replacement project is located in the town of
Rockingham on I-91 just north of Exit 6. The project included the complete removal and replacement of both bridges 24S and 24N which span the Williams River and the Green Mountain Railroad. The new bridges are constructed of precast post-tensioned girders sitting on top of cast-in-place concrete columns with an overall structure length of 860 feet and a height of 140 feet. Both the Northbound and Southbound bridges were fully open to traffic in the Fall of 2022.

EIV provided quality assurance management, construction inspection and materials testing services throughout the duration of this project. EIV team members were responsible for surveying, plan review, ongoing assurance of safety compliance, and monitoring the jobsite for compliance with all environmental permits and plans.
