Abstract:

The Port Authority of New York and New Jersey has embarked on a �37,000,000 project to totally replace the upper roadway of the 46-yr old George Washington Bridge. The scheme, chosen from 16 alternatives, calls for replacement of the existing reinforced concrete deck with an orthotropic steel one. In a unique installation procedure, a minimum section of the deck is saw-cut, removed and replaced with offsite prefabricated and prepaved panels, within a ten-hr night work period. The redecking should take two years to complete, cause minimal traffic inconvenience, and have a structural life expectancy of 20 years. The orthotropic panels, which are supported on the existing floor beam framing system contain some 10,000 tons of weathering steel and have a 1�-in. thick asphaltic concrete pavement.
