Lower Hack

The Lower Hack Lift Bridge is a single span, steel vertical lift bridge which was erected in 1927 and carries three active tracks on the Morristown Line over the Hackensack River in Hudson County, NJ. Throughout the years, IEW Construction Group has worked with NJ Transit on various aspects of maintenance and repair of this intricate and historic bridge. IEW Construction Group’s latest work on this bridge was to remove and replace all stairways and ladders, renew the bridge machinery and operator’s house and perform a detailed inspection of the bridge’s sheaves. One million pounds of steel were lifted and placed using air and manual hoists, highlighting IEW’s skills at rigging and material handling. Work was performed in 4 hour windows, coordinating with NJ Transit around electrified facilities and maintaining train traffic.
