November 13

On 13 November 1927, the Holland Tunnel officially opened to traffic, creating the first direct road link between New Jersey and Manhattan under the Hudson River. Engineers Clifford Milburn Holland and Ole Singstad designed the tunnel's innovative ventilation system to clear exhaust from the enclosed space. Stretching 8,558 feet, the tunnel dramatically reduced travel time and congestion on ferries that previously carried vehicles. Its completion represented a major achievement in civil engineering and urban planning during the Roaring Twenties. The tunnel's success spurred further expansion of automobile infrastructure in the United States. Today, it remains a critical artery for commuters and commerce in the New York metropolitan area.

In November 2013, 4 World Trade Center officially opened its doors in Lower Manhattan, New York City. The 978-foot-tall building, designed by architect Fumihiko Maki, features over two million square feet of office space. It became the fourth tower completed as part of the rebuilding effort following the September 11 attacks. The opening symbolized resilience and renewal for the city and its residents. Major tenants included prestigious financial firms and media companies, reinforcing the site's role as a global business hub.
