When the U.S. Highway System was established in 1926, the routing of US 1 in New Jersey was to follow the Lincoln Highway from the Lower Trenton Bridge in Trenton to Newark, which was Route 13 between Trenton and New Brunswick and Route 1 north of there. From Newark, the route followed present-day US 1/9 Truck east toward Jersey City, where it was to head to the Holland Tunnel. The Lincoln Highway the first transcontinental highway in the United States created in 1913 to link New York City to San Francisco. Route 13 had been legislated along the Trenton to New Brunswick portion in 1917.
