PROJECT HIGHLIGHTS: BRATTLEBORO BRIDGE
The I-91 Brattleboro Bridge is a new 3-span cast-in-place segmental bridge. This structure will carry both Northbound and Southbound lanes of I-91 once complete, replacing two existing separate truss structures built in the 1950's. The main span is 510' long with symmetrical 263' side spans. Segments double cell boxes that are 104'-8" wide and 30' deep at the pier.
McNary Bergeron is providing construction engineering services to the design build team including an independent review of the form traveler system and review of the existing bridge demolition sequences developed by the team. The form traveler consists of three main support horses and adjustable formwork that can accommodate the variable depth webs and variable width bottom slab.
