Concrete pouring devices used for the Tappan Zee Bridge replacement project returned to the construction site recently after part of one collapsed in December and temporarily halted concrete production.
Tappan Zee Constructors LLC, the joint venture that has designed and run the project that is estimated to cost $3.9 billion, announced on Friday that two concrete pouring batch plants passed a required test that has allowed them to return to work.
A silo, which is used to hold the stone-sand concrete mix, fell onto two nearby silos sitting on floating plants on the Hudson River about three months ago.
Tappan Zee Constructors also announced that work recently resumed on reinforcing steel in the main span of the bridge following the two-month winter shutdown.
