New Jersey Route 29

Route 29 northbound through downtown Trenton, with the Delaware River on the left

Route 29 begins at a modified cloverleaf interchange with I-195 and I-295 in Hamilton Township, and it serves as the western continuation of I-195, heading to the northwest as a six-lane freeway. The route has an interchange with Route 129, a spur of Route 29 which connects to US 1, with a northbound exit and southbound entrance. At this interchange, the route passes over NJ Transit's River Line.[1] Route 29 narrows to four lanes past this interchange and crosses into Trenton. The route comes to a southbound exit and entrance for Lamberton Road. At this point, Route 29 becomes the Delaware River Scenic Byway, a state scenic byway that was also designated a National Scenic Byway in 2009.[2][3] Route 29 runs along the bank of the Delaware River and enters a truck-restricted tunnel that passes by historic houses and Riverview Cemetery.[1][4][5] Within this tunnel, Route 29 features a southbound exit and northbound entrance for Lalor Street.[1] The route emerges from the tunnel as the John Fitch Parkway and passes east of Trenton Thunder Ballpark, the home ballpark of the Trenton Thunder baseball team. The road comes to a traffic light at Thunder Road/Cass Street where it widens back to six lanes.[1][6] Route 29 meets South Warren Street at another traffic light. The median widens and it passes under the Morrisville–Trenton Railroad Bridge, which carries Amtrak's Northeast Corridor over the Delaware River.[1]

Route 29 passes under the Trenton–Morrisville Toll Bridge, which carries US 1 over the Delaware River. Access to US 1 southbound is provided by ramps from Route 29 while access to Route 29 from northbound US 1 is provided by South Warren Street.[1] Route 29 passes under the Lower Trenton Bridge and the median narrows again. It interchanges with Market Street, which provides access to Route 33, and then features an interchange with Memorial Drive which provides access to the New Jersey State House with a northbound exit and southbound entrance. Route 29 crosses the Assunpink Creek and features an interchange which provides access to South Warren Street with exits in both directions but only a northbound entrance.[1] Route 29 continues to a cloverleaf interchange with Calhoun Street (County Route 653, CR 653), which provides access to the Calhoun Street Bridge over the Delaware River. Riverside Avenue exits as a frontage road paralleling the northbound lanes of Route 29 before the road features a northbound exit for Hermitage Avenue. Route 29 comes to a partial interchange with Parkside Avenue, with a northbound exit and southbound entrance, and then features a northbound exit for South Eastfield Avenue.[1]

The freeway portion of Route 29 ends at the intersection with Lee Avenue and it continues northwest along the Delaware River as a four-lane expressway. The route meets the southern terminus of CR 579 (Sullivan Way). The median widens again and then narrows as the route meets the southern terminus of Route 175, a former alignment of Route 29 that currently serves as a frontage road. Route 29 crosses into Ewing Township and becomes the Daniel Bray Highway. It passes under the West Trenton Railroad Bridge, which carries CSX's Trenton Subdivision and SEPTA's West Trenton Line over the Delaware River.[1] Route 29 intersects Route 175 again and then comes to a complex interchange with I-295, with the ramps within the median of Route 29, just to the east of the Scudder Falls Bridge.[1]

Upon crossing the Delaware and Raritan Canal, Route 29 narrows down to a two-lane undivided road called River Road. It continues along the Delaware River, next to the Delaware and Raritan Canal, which runs between Route 29 and the river. The route intersects the northern terminus of Route 175. Farther north, Route 29 enters Hopewell Township and continues into a more rural setting shaded with trees.[6] Route 29 heads to Washington Crossing State Park, where it intersects CR 546, which heads east on Washington Crossing-Pennington Road, and the approach to the Washington Crossing Bridge, which continues into Pennsylvania and connects to Pennsylvania Route 532 (PA 532).[1][6] Route 29 continues north along the Delaware River through Titusville, passing by Washington Crossing State Park.[6]

Route 29 crosses into West Amwell Township in Hunterdon County. It enters Lambertville, where Route 29 becomes a four-lane divided highway.[1] At the intersection of South Main Street, Route 29 becomes concurrent with Route 165.[7] The route becomes an undivided highway again and meets the western terminus of CR 518 (Brunswick Street). It meets Route 179 (Bridge Street), where Route 165 ends and Route 29 turns west for a one-block wrong-way concurrency with the two-lane, undivided Route 179, lasting to the intersection of Main Street, where Route 29 turns north on Main Street.[1][7]

Route 29 northbound past CR 519 in Delaware Township

Route 29 follows Main Street north through Lambertville, crossing into Delaware Township. It comes to an interchange with US 202 just east of the New Hope–Lambertville Toll Bridge, with access to northbound US 202 and from southbound US 202 provided by way of Alexauken Creek Road.[1] Route 29 continues along the Delaware River and enters Stockton. The route intersects Bridge Street, which crosses the Delaware River on the Centre Bridge–Stockton Bridge and continues into Pennsylvania as PA 263.[1][6] Shortly after that intersection, Route 29 intersects the southern terminus of CR 523 (Stockton-Flemington Road). Route 29 crosses back into Delaware Township, where it meets the southern terminus of CR 519 (Kingwood-Stockton Road).[1]

Route 29's mis-signed northern terminus when entering Frenchtown. Route 29 continues to Frenchtown and Route 12 despite the signage.

Route 29 makes a sharp left turn and heads west along the river as a rural road, crossing into Kingwood Township, where the name of the road changes from Main Street to Daniel Bray Highway. Here, it intersects with CR 651 (Byram-Kingwood Road). The route bends to the north and continues along the Delaware River for several miles, crossing into Frenchtown, where the route becomes Trenton Road.[1] Upon entering Frenchtown, an end shield for northbound Route 29 is posted to mark the end of state maintenance, which officially ends at the Washington Street intersection, where maintenance is transferred to the county.[1][8] Despite this, Route 29 officially continues farther north along Trenton Road to its northern terminus at Route 12 (Bridge Street/Race Street), a short distance east of Route 12’s western terminus at the Uhlerstown–Frenchtown Bridge. The southern terminus of CR 513 is located a block north of the northern terminus of Route 29 along Route 12.[1]
