Thruway Authority to Continue Tappan Zee Bridge Deck Replacement Project

The New York State Thruway Authority announced today that deck replacement work on the Tappan Zee Bridge will continue the week of March 30, 2009. 

This stage of work will begin with preparation of the deck surface for the installation of the new modular joints in the main span and west deck truss on Wednesday, April 1, 2009.

Prep work for the installation of new deck joints is weather-dependent and subject to change. Updates will be issued announcing any change in schedule. Lane closures during this operation:

Wednesday, April 1

  • Work will begin at 8 p.m. resulting in the closure of two right southbound lanes, with an additional right southbound lane closing at 10 p.m., until 6 a.m. from Interchange 10 to the east deck truss on the Tappan Zee Bridge.

Thursday, April 2

  • Work will begin at 8 p.m. resulting in the closure of two right southbound lanes, with an additional right southbound lane closing at 11 p.m., until 6 a.m. from Interchange 10 to the east deck truss on the Tappan Zee Bridge.

During Wednesday and Thursday nights’ operations, the southbound entrance at Interchange 10 will be closed and southbound traffic will be detoured on a posted detour route through Nyack to the entrance to the southbound roadway at Route 59 near Interchange 11.

Two left lanes in the northbound direction from Interchange 8 to milepost 13 will also be closed from 10 p.m. to 6 a.m. as part of this work. 

Due to the northbound lane closures, the entrance ramp from Broadway (southbound) in Tarrytown will also be closed from 10 p.m. until 6 a.m. All traffic will be detoured to the entrance ramp from Route 119. 

These lane closures are for the prep work for the installation of new deck joints on the southbound main span and southbound west deck truss.  All lanes are expected to be open by 6 a.m. the following day.

Friday, April 3

  • Work will begin at 9 p.m. resulting in the closure of two right southbound lanes, with an additional right southbound lane closing at 11 p.m., until 8 a.m. from Interchange 10 to the east deck truss on the Tappan Zee Bridge.

Weather permitting, the deck replacement project is slated for completion by late August 2009.
