Project Description

The Portal Bridge over the Hackensack River, originally built in 1910, is used by 500 NJ Transit and Amtrak trains daily between Newark and New York Penn Stations.  The existing structure is a draw bridge that opens during navigational traffic and impedes the rail traffic.  Under this $1.34 billion design project, the existing bridge is replaced with two permanent structures with adequate clearance for navigational traffic below.  The permanent structures are long span through trusses.

We provided design services and prepared construction documents for the installation of construction access platforms, estimated at $49 million. The 33-foot wide platforms are steel framed structures with timber decking supported on steel bents. The steel bents are supported by end bearing steel piles.  These platforms facilitate the construction of a permanent viaduct and support heavy crane movement.  SJH also was involved with the design of the permanent viaduct structures. We are currently involved in the design of retaining walls.
