The Sawtooth Bridges are a pair of railroad bridges on the Northeast Corridor (NEC) known individually as Amtrak Bridge No. 7.80 and Amtrak Bridge No. 7.96. They are located in the Meadowlands in Kearny, New Jersey, between Newark Penn Station and Secaucus Junction at a stretch where the rights-of-way of Amtrak, NJ Transit, PATH, and Conrail converge and re-align. The name refers to their appearance and the numbers refer to the milepoint (MP) from New York Penn Station. Originally built by the Pennsylvania Railroad, they are now owned and operated by Amtrak. They are slated for replacement as part of the Gateway Program, an infrastructure-improvement program along the NEC.
