Regional Training Institute Vehicular Bridge - Pembroke, NH | York Bridge Concepts - Timber Bridge Builders

Regional Training Institute Project Overview

York Bridge Concepts™ has designed & built a high profile Timber Vehicular Bridge at The Regional Training Institute. The RTI campus is a training facility utilized for various exercises, drills and a Barracks facility to house visiting members of the Guard. The bridge features two twelve foot wide traffic lanes with a 60 foot center span over the ravine, and a centerline crown that allows for water to easily drain off the bridge from its longitudinal highpoint. A LEED-based project, half of the lumber utilized for this bridge is FSC-certified – ensuring that the materials originate from well managed forests. This magnificent York Timber will be enjoyed by The National Guard for generations.

Client Testimonial

"Sometimes in the field we get to implement and see the tangible aspects of a whole lot that’s happened behind the scenes for many months. As with most successful projects, RTI had a whole team of people who contributed to the effort. The attention to detail is refreshing, particularly in an industry where it seems to be becoming harder and harder to find. York’s attention to detail is appreciated, even down to the logo of the bolts facing the same direction. We noticed and love the bridge. Congratulations on a job well done and on finishing ahead of schedule."
–Matt Walsh, Assistant Superintendent, Eckman Construction
"The quality of workmanship and skilled / professional employees are a testament to your success as a company. If any of our future projects require a timber bridge, I would not hesitate to recommend YBC as a capable and highly regarded company."
–John M. Couture, Project Manager, Eckman Construction
