   Route 29 is a state highway in the U.S. state of New Jersey . It runs 34 @.@ 76 mi ( 55 @.@ 94 km ) from an interchange with Interstate 295 ( I @-@ 295 ) in Hamilton Township in Mercer County , where it continues as I @-@ 195 , to Route 12 ( Bridge Street / Race Street ) in Frenchtown , <unk> County . Between the southern terminus and I @-@ 95 , the route is a mix of freeway and four @-@ lane divided highway that runs along the Delaware River through <unk> . This section includes a truck @-@ restricted tunnel that was built along the river near historic houses and <unk> Cemetery . North of I @-@ 95 , Route 29 turns into a scenic and mostly two @-@ lane highway . North of the South <unk> Tunnel , it is designated the Delaware River Scenic Byway , a New Jersey Scenic Byway and National Scenic Byway , that follows the Delaware River in mostly rural sections of Mercer County and <unk> County . The obsolete Delaware & <unk> Canal usually stands between the river and the highway . Most sections of this portion of Route 29 are completely <unk> due to the tree canopy . Route 29 also has a spur , Route 129 , which connects Route 29 to U.S. Route 1 ( US 1 ) in <unk> . 
   Route 29 was initially designated in 1927 to run from downtown <unk> to Newark , following present @-@ day Route 179 and US 202 between <unk> and <unk> and US 22 between <unk> and Newark . The route between <unk> and Frenchtown was originally Route <unk> . In 1953 , Route 29 was shifted to follow the alignment of Route <unk> to avoid the <unk> with the U.S. Routes . Route 29 between South Warren Street in <unk> and I @-@ 95 in Ewing Township was upgraded to a four @-@ lane highway , with a portion of freeway , in the 1950s and 1960s . In 1995 , the southern freeway part of Route 29 between I @-@ 195 / I @-@ 295 and Route 129 in Hamilton Township was completed . This freeway section was linked to the rest of Route 29 by a tunnel completed in 2002 . A realignment of Route 29 in <unk> by the 2000s made the route concurrent with the entire length of 0 @.@ 26 @-@ mile @-@ long ( 0 @.@ 42 km ) Route 165 .

   The current route was originally legislated in 1911 as part of the Delaware River Drive , a named state highway that was proposed to run from along the Delaware River from <unk> to the New York border in <unk> Township . Route 29 was originally defined in 1927 to run from <unk> to Newark . The original route ran from downtown <unk> along State Street and <unk> Drive . From there , it followed its current alignment to <unk> , where it followed present @-@ day Route 179 to <unk> to present @-@ day County Route <unk> , which it followed to Woods Tavern . The route turned north on U.S. Route 206 ( also designated Route 31 ) and followed that route to <unk> , where it followed U.S. Route 22 to Newark . The current alignment of Route 29 from <unk> to Route 12 in Frenchtown was designated Route <unk> in 1927 . 
   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 . 
   Plans for a limited @-@ access route along the Route 29 corridor go back to 1932 , when a parkway was proposed along the Delaware River between <unk> and <unk> ; this proposal never materialized . Plans for a freeway were resurrected in the early 1950s to construct a road , the John Fitch Parkway , that was to run from Hamilton Township to Interstate 95 in Ewing Township . This road was built between 1954 and 1957 from South Warren Street in <unk> to present @-@ day Interstate 95 in Ewing Township . Construction of this portion John Fitch Parkway took up much of <unk> ’ s available waterfront along the Delaware River . The former alignment of Route 29 in the northern part of <unk> and in Ewing Township became Route 175 . 
   Between 1990 and 1995 , the Route 29 freeway was built between the Interstate 195 / Interstate 295 interchange and Route 129 in Hamilton Township . A two @-@ lane street , <unk> Road , connected the two freeway sections . Plans were then made to fill the gap between the two freeway sections in <unk> . Construction began in 1997 on the Route 29 freeway between Route 129 and the <unk> @-@ <unk> Railroad Bridge . The road was to include two traffic lights at Cass Street and South Warren Street and a tunnel which was to be built as a covered roadway on the bank of the Delaware River . The tunnel was originally scheduled to be complete by 2001 but was delayed after the Army Corps of Engineers discovered many environmental violations that occurred with construction of the tunnel . The roof was put in place in October 2001 and the tunnel officially opened to traffic on March 2 , 2002 . A restriction to trucks over 13 tons was put in place and made permanent in November 2002 . 
   By the 2000s , the state gave the part of Route 29 ( South Main Street ) between Route 165 and Route 179 in <unk> to the city , and Route 29 was rerouted to use all of Route 165 and one block of Route 179 . Prior to this , South Main Street had been turned one @-@ way southbound . Route 165 , which is only signed on overhead street signs , still exists , though it is fully concurrent with Route 29 .
