Route 29 is a state highway in the U.S. state of New Jersey. Signed north-south, it runs 34.76 mi (55.94 km) from an interchange with Interstate 295 (I-295) in Hamilton Township in Mercer County, where the road continues east as I-195, northwest to Route 12 in Frenchtown, Hunterdon County. Between the southern terminus and I-295 in Ewing Township, the route is a mix of freeway and expressway that runs along the Delaware River through Trenton. This section includes a truck-restricted tunnel that was built along the river near historic houses and Riverview Cemetery. North of I-295, Route 29 turns into a scenic and mostly two-lane highway. North of the South Trenton 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 Hunterdon County. The obsolete Delaware & Raritan Canal usually stands between the river and the highway. Most sections of this portion of Route 29 are completely shaded 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 Trenton.
The Hutchinson River Parkway is a controlled-access parkway in southern New York in the United States. It extends for 18.71 miles (30.11 km) from the Bruckner Interchange in the Throggs Neck section of the Bronx to the New York–Connecticut state line at Rye Brook. The parkway continues south from the Bruckner Interchange as the Whitestone Expressway (Interstate 678) and north into Greenwich, Connecticut, as the Merritt Parkway. The roadway is named for the Hutchinson River, a 10-mile-long (16 km) stream in southern Westchester County that the road follows alongside. The river, in turn, was named for English colonial religious leader Anne Hutchinson.
The Merritt Parkway is a controlled-access parkway in Fairfield County, Connecticut, with a small section at the northern end in New Haven County. Designed for Connecticut's Gold Coast, the parkway is known for its scenic layout, its uniquely styled signage, and the architecturally elaborate overpasses along the route. As one of the first, oldest parkways in the United States, it is designated as a National Scenic Byway and is also listed in the National Register of Historic Places. Signed as part of Route 15, it runs from the New York state line in Greenwich, where it serves to continue the Hutchinson River Parkway, to Exit 54 in Milford, where the Wilbur Cross Parkway begins. Facing bitter opposition, the project took six years to build in three different sections, with the Connecticut Department of Transportation constantly requiring additional funding due to the area's high property value. The parkway was named for U.S. Congressman Schuyler Merritt. In 2010, the National Trust for Historic Preservation called the Merritt Parkway one of "America's 11 Most Endangered Historic Places".

The Francis Scott Key Bridge that crossed over the Patapsco River was included in this section of the route before the bridge's collapse on March 26, 2024. The bridge and its approaches were maintained by the Maryland Transportation Authority (MDTA), while the remainder of the Baltimore Beltway is maintained by the Maryland State Highway Administration (MDSHA).

Upon reaching Dover, DE 1 becomes the Korean War Veterans Memorial Highway, a freeway that is partially tolled. Between Dover and Tybouts Corner, DE 1 parallels U.S. Route 13 (US 13), crossing over and featuring interchanges with it multiple times. Past Tybouts Corner, the freeway heads north parallel to DE 7 to the northern terminus of DE 1 in Christiana.

The freeway ends at a junction with the tolled Massachusetts Turnpike in Sturbridge, Massachusetts. The entire route was formerly signed as Route 15.
Exit numbers in the United States are assigned to freeway junctions, and are usually numbered as exits from freeways. Exit numbers generally are found above the destinations and route number(s) at the exit, as well as a sign in the gore. Exit numbers typically reset at political borders such as state lines. Some major streets also use exit numbers. Freeway exits in the United States are usually numbered in two formats: distance-based and sequential.
U.S. Route 5 (US 5), a north–south United States Numbered Highway that is generally paralleled by Interstate 91 (I-91), begins at the city of New Haven in Connecticut and heads north through western Massachusetts and eastern Vermont to the international border with Canada.
