Bridge Deck Work Cuts River Road to 1 Lane

Installation of the bridge’s concrete road deck panels near the Rockland shoreline began Dec. 10 and will continue through Dec. 18.

Tappan Zee Constructors, LLC (TZC) cranes will lift the prefabricated deck segments into place atop previously-installed structural steel girders.

Safely accomplishing the work will require reducing River Road/Piermont Avenue to one lane during weekdays. Flag persons will keep traffic moving by alternating the directional flow between north and south. TZC will also periodically hold traffic on River Road/Piermont Avenue for 6-minute intervals to enable the safe movement of deck panels and other materials.

Nearly 6,000 high-strength concrete deck panels will be installed for the new crossing’s approach spans. The panels are prefabricated at an off-site location and barged down river from the project’s Port of Coeymans facility in Albany County. TZC will continue installing the approach span deck sections across the river over the coming year.

Also during the week: continued construction of foundations for noise barriers along the southbound Thruway between the South Broadway bridge and River Road.

The construction work involves drilling holes into the soil to install the foundations. After the foundations are installed, concrete panels that form the noise barriers will be installed. The barriers will be treated with sound-absorbing material to further reduce traffic noise to the nearby community.
