During the closure the contractor will be working on bringing the road grade up to meet the new alignment and tie-in for the Vermont/New Hampshire Route 119 bridge over the Connecticut River.

The location of the closure is approximately 1000 feet south of the current intersection of VT 142 and VT/NH 119. Access to both Royal Road from the southern approach and to 28 Vernon Street from the north will be maintained and flaggers will be present to assist local motorists with access to these locations as needed.

The gravel wetland construction continues and is awaiting the installation of a drainage structure in order to bring this work to completion.

Installation of panels and panel straps for the northern MSE wall will continue next week. Excavation for the gravel wetland south of the bridge abutment is ongoing along with the installation of drainage structures. The last of the cofferdam sheets that were used for the gravel wetland have been removed. Form work has begun at Abutment A (the Vermont abutment) for the backwall and will continue into next week with a concrete placement tentative for the end of the week.

Pile driving operations are complete at Pier 2 as of last week.
