Thruway Authority to Continue Tappan Zee Bridge Deck Replacement Project

The New York State Thruway Authority announced deck replacement work on the Tappan Zee Bridge will continue the week of May 25, 2009.

On Tuesday, May 26 through Thursday, May 28, installation of new modular joints in the main span and the west deck truss will continue in the center lanes. 

On the evenings of Friday, May 29 and Saturday, May 30, the Authority’s contractor will be installing transition ramps of approximately 50 feet of asphalt leading up to steel plates on a modular joint on the west deck truss of the Tappan Zee Bridge. The transition ramps will cover the entire width of the bridge at each bridge joint location and will gradually thicken until the ramp is flush with the top of the roadway plate(s). It is anticipated the asphalt ramps will provide a smooth transition over the roadway plates thereby minimizing impacts to motorists. Additionally, the ramps are to encourage drivers to continue traveling at reasonable speeds.  In addition, the contractor will be removing one of the asphalt transition ramps on the west deck truss, where the center portion of the new bridge joint is completed.

All work is weather-dependent and subject to change.

Updates will be issued announcing any change in schedule. Lane closures during this operation:
