The main construction phase is set to start on a US$146 million project to rehabilitate the Patroon Island Bridge in the US state of New York.

The deck replacement project will be carried out while the bridge remains in use and most work will be carried out at night with lane closures in place.

The construction contractors for the NY Works project are Halmar International and A Servidone-B Anthony Construction Corp JV.

The bridge carries Interstate 90 over the Hudson River between Rensselaer and Albany. The project involves rehabilitating the Patroon Island Bridge and all the ramps comprising the I-90 interchange with I-787. Work will include replacing the bridge decks and bearings, steel repairs and repainting, as well as replacing or repairing the substructures of the interchange. Precast concrete deck panels will be used to speed construction.

Preparatory work began last year and continued through the winter.  Four concrete piers supporting the ramps that make up interchange have already been demolished.

Work to demolish the remaining piers and build new ones will continue through the summer and into the autumn, and work to install traffic monitoring systems is already under way.  Work to remove and replace the deck is expected to begin in late April in the eastbound direction.

The project is expected to be completed this year.
