 The alignment of Route 29 between <unk> and <unk> was eventually shifted to follow present @-@ day U.S. Route 202 , which was also Route 30 ( now Route 31 ) between <unk> and Flemington and Route 12 between Flemington and <unk> . In 1938 , Route <unk> was planned as an extension of Route <unk> from Frenchtown to Route 28 ( now Route 122 ) in Alpha . While this road was never built , much of the alignment north of Milford is served by County Route <unk> . In 1948 , a spur route , Route <unk> , was created , running along U.S. Route 202 ( Bridge Street ) in <unk> to the New Hope @-@ <unk> Bridge . In the 1953 New Jersey state highway renumbering , Route 29 was <unk> to continue north from <unk> to Frenchtown on Route <unk> , and the Route 29 designation between <unk> and Newark was removed in favor of U.S. Route 202 between <unk> and <unk> and U.S. Route 22 between <unk> and Newark . The section of former Route 29 between Route <unk> and Route <unk> became Route 165 .
