Route 1 used the old New Brunswick and Cranbury Turnpike (Georges Road) to Cranbury and the Bordentown and South Amboy Turnpike to Robbinsville. At Robbinsville, it turned west on Nottingham Way, running to the Trenton line on Greenwood Avenue. This section was all taken over in 1919. Route 2 left Trenton on Broad Street, known as the White Horse Road, to White Horse. At White Horse it turned south on what was known as the White Horse Road Extension and Trenton Road, intersecting the Bordentown and South Amboy Turnpike northeast of Bordentown. There it turned southwest along the turnpike, named Park Street in Bordentown, continuing on the Florence Road (old Burlington Turnpike) through Florence Township to Burlington. From Burlington, Route 2 kept going southwest on the Westfield and Camden Turnpike, ending at the Camden border at Westfield Avenue. This was also taken over in 1919. Several amendments in 1922 added to the routes. Route 2 was extended southwest through Camden to the proposed Benjamin Franklin Bridge, and a spur was added from Five Points northwest to the Tacony-Palmyra Ferry. More important was the extension of Route 1 north to the planned Holland Tunnel. Route 1 Extension: 1922-1932 The Route 1 Extension is considered to be the first controlled-access highway or "super-highway" in the United States. The highway was built to carry large amounts of traffic from the Holland Tunnel to the rest of New Jersey. The south end of the extension was at Edgar Road in Linden, just south of Elizabeth and the Bayway Circle. Edgar Road had been built as a turnpike in the 19th century, and now serves as part of U.S. Route 1/9 south of the extension. The road was built from 1925 to 1932. All, but the Pulaski Skyway, was finished by 1930. It was a full freeway, mostly elevated on embankments or viaducts, from four blocks west of the Holland Tunnel to just north of Newark Airport, and a high-speed surface road from there to Elizabeth (and beyond). In summer of 1923, the NJ State Highway Commission decided that it would be an entirely new route, from the Lincoln Highway (Route 1) southwest of Elizabeth to the Holland Tunnel. Existing roads, which passed through downtown Newark, were already experiencing major congestion. Frederick Lavis, Assistant Construction Engineer of the New Jersey State Highway Department, explained this decision: The new highway will be the easterly end of
