The Gateway Program Development Corp. on Monday released two new animations depicting the Portal North Bridge and Hudson River Tunnels projects at completion.
The two projects are the first in the Gateway Program and the most critical to replacing a one-track in, one-track out system that is increasingly failing 200,000 riders a day.
The first animation shows the full build-out of the Portal North Bridge project, which spans nearly 2.5 miles from Kearny to Secaucus, and includes the replacement of the 107-year-old swing bridge over the Hackensack River. The existing bridge gets stuck causing substantial train delays when opening and closing to accommodate river traffic as required by federal law.
The second animation depicts the route of the new Hudson River Tunnel from New Jersey, under the Palisades and Hudson River, to the west side of Manhattan.
The new tunnel will be the first built under the Hudson in more than 80 years, and the first new rail tunnel since completion of the existing tubes in 1910 by the Pennsylvania Railroad.
The existing tunnels suffered extreme water damage from Superstorm Sandy in 2012.
Gateway backers contend the project needs to be done to support the economy and eliminate a single point of failure on the nation’s busiest stretch of railways, causing delays that ripple throughout the rail system from Washington, D.C., to Boston.
