Construction Update
Brattleboro-Hinsdale
BF A004(152)
DATE: Thursday, January 4, 2024
TRAFFIC IMPACT:
No traffic impacts are scheduled for next week.
The contractor and engineering teams are continuing to work on a Traffic Control Plan for the upcoming delivery of the structural steel to the Pier 1 site. The delivery route will be along New Hampshire and Vermont Route 119. During deliveries and with advance notice, locals can expect short duration closures of NH/VT 119. This impact will include the twin bridges and the intersection of Bridge Street to Vermont Route 142 and Canal Street. The delivery schedule and related details are being worked out and will be shared once formalized.

CONSTRUCTION ACTIVITIES:
The contractor has begun to advance structural steel across Pier 2 to the temporary shoring towers. This work will continue into next week. De-watering at Pier 1 site encountered several challenges last week and additional work has taken place to remediate the situation this week. The saturated conditions of the site and soil conditions have necessitated that the cofferdam be tighter in order to allow less water infiltration so the de-watering system will not be overwhelmed by the volume. The contractor has installed vertical forms at all four corners of the cofferdam and anticipates placing concrete today in order to achieve a better seal. The contractor will attempt de-watering again next week once the concrete has set up. Once a dry excavation can be maintained, the contractor will begin to install the 80 foot rebar cages in the 9 pier piles which may begin as early as next week. Footing formwork and re-bar installation may begin next week as well, overlapping with the pile operations.

LOCATION:
The Hinsdale, NH to Brattleboro, VT bridge project will replace the existing twin truss bridges on New Hampshire Route 119 over the Connecticut River with a single, new structure approximately 1800′ long. On the Vermont side, the new structure will begin on Vermont Route 142 – about 1000′ south of the current intersection of VT 142 and NH 119. The new configuration will connect to NH 119 in New Hampshire east of the George’s Field Road/NH 119 intersection.
PROJECTED COMPLETION: Fall 2024.
