“Portfolio,” a new blog by the Port Authority of New York and New Jersey, was launched on April 28 and will spotlight the largely unknown but critical role that transportation infrastructure plays in the region.

The blog, available at portfolio.panynj.gov, will offer a behind-the-scenes look at the Port Authority’s airports, six tunnels and bridges, port facilities, and the PATH rail system to enhance the public’s general knowledge, interest, and understanding about Port Authority facilities.

Through vintage photographs and stories from the Port Authority archives, the blog will highlight the role the agency has played for almost a century in shaping the New York metropolitan region. “Portfolio” will also serve as a platform from which to spotlight interesting stories that rarely make the news, including those involving the many unsung Port Authority staff members who operate and maintain these facilities.

Upcoming posts will cover a broad palate of content such as customer-service amenities in airport terminals, NextGen satellite technology, smart technology on Port Authority bridges, and the replacement of cables on the George Washington Bridge.

In a nod to the agency’s storied 94-year past, the “Portfolio” was named after a quarterly journal which the agency published some 25 years ago as a forum for contemporary thinking on regional, national, and international transportation issues.
