This past week, demolition work began on the western portion of the Rochambeau Bridge.

Demolition of the bridge deck will continue to take place between the hours of 6 am to 6 pm, Monday through Friday; the demolition is anticipated to be completed by February 12, 2021.

The work requires hoe-ramming, and residents may notice this generates noise and vibrations. We are required to monitor both — noise by noise meters, and vibrations by a seismograph near the bridge.

The Lake Zoar channel under the Rochambeau Bridge, in Newtown and Southbury, will close during bridge demolition until January 22.

Demolition operations will remove the concrete bridge deck on the former westbound portion of the Rochambeau Bridge utilizing the Poseidon flexi-float.

About the Rochambeau Bridge Reconstruction Project

The Connecticut Department of Transportation began construction activities for the rehabilitation of the Rochambeau Bridge, in Newtown and Southbury on Monday, June 15, 2020.

The project consists of two bridges, collectively called the “Rochambeau Bridge,” which carry I-84 over the Housatonic River. The existing bridges have extra-wide shoulders, so there is sufficient room to place bidirectional traffic, with two lanes in each direction, on one of the bridges while the other bridge is reconstructed. The first major traffic shift has placed both directions of I-84 traffic on I-84 eastbound utilizing crossovers built in the median of I-84. The I-84 westbound bridge is currently being partially demolished and reconstructed while this shift is in place.

Once the new I-84 westbound bridge is completed, traffic will be shifted onto the new bridge while the I-84 eastbound bridge is reconstructed, with temporary crossovers built in a similar manner, in the median of I-84.
