Much of US&nbsp;9 is a two-lane road, with some expansions near more populous areas. The major exception to this is [[central Jersey|central]] and [[North Jersey|northern]] New Jersey, where it is a wide four-lane (or six-lane) divided strip, especially during much of its concurrency with US&nbsp;1 and in [[Middlesex County, New Jersey|Middlesex]] and [[Monmouth County, New Jersey|Monmouth]] counties. New York boasts a few similar sections, as well as two short expressway sections near [[Albany, New York|Albany]].

In New Jersey, US&nbsp;9 mainly runs parallel to the [[Garden State Parkway]], and, in New York, most of US&nbsp;9 runs parallel to [[Interstate 87 (New York)|I-87]].

US&nbsp;9 runs an east–west path through [[Sussex County, Delaware|Sussex County]], running east from [[U.S. Route 13|US&nbsp;13]] in [[Laurel, Delaware|Laurel]], passing through [[Georgetown, Delaware|Georgetown]], east to [[Lewes, Delaware|Lewes]], where it leads to the [[Cape May–Lewes Ferry]], which carries US&nbsp;9 across the [[Delaware Bay]] to New Jersey.<ref>{{cite news |url = https://www.newspapers.com/clip/113482568/cape-maylewes-ferry-and-us-route-9/ |title = Lewes ferry beats the odds in a tricky transit sea |work = [[The Philadelphia Inquirer]] |date = August 1, 1976 |access-date = November 22, 2022 |via = [[Newspapers.com]] }}</ref> US&nbsp;9 was extended to Delaware by way of the Cape May–Lewes Ferry in 1974, replacing Delaware Route&nbsp;28 (DE&nbsp;28) between Laurel and Georgetown and [[Delaware Route 18|DE&nbsp;18]] between Georgetown and Lewes. US&nbsp;9 runs concurrent with [[Delaware Route 404|DE&nbsp;404]] between Georgetown and the Five Points intersection near Lewes.

===New Jersey===

From [[Cape May, New Jersey|Cape May]], US&nbsp;9 runs north parallel to the [[Garden State Parkway]], until briefly joining the Parkway to cross [[Great Egg Harbor Bay]] on the reconstructed [[Great Egg Harbor Bridge]] following the demolition of the [[Beesley's Point Bridge]]. US&nbsp;9 then exits the Parkway north of the bridge (where the Parkway includes a toll on all US&nbsp;9 and Parkway traffic in the southbound direction) and runs through the [[Atlantic City, New Jersey|Atlantic City]] suburbs, until joining the Parkway briefly again to cross the [[Mullica River]] [[estuary]] in the [[New Jersey Pine Barrens|Pine Barrens]] region of [[South Jersey]]. At [[New Gretna, New Jersey|New Gretna]], US&nbsp;9 exits the parkway and parallels wooded areas and marshlands along [[Little Egg Harbor]] and [[Manahawkin Bay|Manahawkin]] and [[Barnegat Bay|Barnegat]] bays, passing [[Manahawkin, New Jersey|Manahawkin]] and paralleling [[Long Beach Island]], until [[South Toms River, New Jersey|South Toms River]] where the highway rejoins the Parkway for a third and final time through [[Toms River, New Jersey|Toms River]]. In Toms River exists the only Parkway/US&nbsp;9 concurrency with interim interchanges at Parkway exits&nbsp;81 and 82, before exiting the parkway at exit&nbsp;83 and continuing north through Toms River to [[Lakewood (CDP), New Jersey|Lakewood]], where the road becomes a divided highway that follows a more inland route through [[Howell Township, New Jersey|Howell Township]], [[Freehold Township, New Jersey|Freehold Township]], [[Manalapan Township, New Jersey|Manalapan Township]], [[Marlboro Township, New Jersey|Marlboro Township]], [[Old Bridge Township, New Jersey|Old Bridge Township]], [[Sayreville, New Jersey|Sayreville]], and into [[Perth Amboy, New Jersey|Perth Amboy]]. From there, the road resumes its parallel course with the Garden State Parkway. After crossing the [[Edison Bridge (New Jersey)|Edison Bridge]] over the [[Raritan River]], it merges with [[U.S. Route 1|US&nbsp;1]] in [[Woodbridge Township, New Jersey|Woodbridge Township]]. The concurrency, an important and busy regional artery, continues past [[Newark Liberty International Airport]] and over the [[Pulaski Skyway]], finally leaving the state along with US&nbsp;1 and [[Interstate 95|I-95]] via the [[George Washington Bridge]].

A large section in northeast New Jersey and a small section in southern New York is [[Concurrency (road)|concurrent]] with [[U.S. Route 1|US&nbsp;1]]. Route shields on this section, which includes the [[Pulaski Skyway]], often show both numbers in the same shield, with an endash or ampersand between (1–9 or 1&9). It is known locally as "one and nine" or "one-nine".

===New York===
{{Main|U.S. Route 9 in New York}}
US&nbsp;9 exits shortly after the George Washington Bridge to go onto New York City's [[Broadway (Manhattan)|Broadway]] north of it, passing over the northern tip of [[Manhattan]] Island via the toll-free [[Broadway Bridge (Manhattan)|Broadway Bridge]], through [[the Bronx]] and into [[Westchester County, New York|Westchester County]], where in some towns it follows the old [[Albany Post Road]], which dates from the early days of the nation's existence.

Following the [[Hudson River]] closely as a busy surface road through the many suburban river villages and past [[National Historic Landmark]]s such as [[Sunnyside (Tarrytown, New York)|Sunnyside]] and [[Kykuit]], US&nbsp;9 becomes the [[Croton Expressway]] between [[Croton-on-Hudson, New York|Croton-on-Hudson]] and [[Peekskill, New York|Peekskill]]. That section ends at the Annsville Circle junction with [[U.S. Route 6|US&nbsp;6]] and [[U.S. Route 202|US&nbsp;202]], where US&nbsp;9 returns to two-lane status as it follows the old post road inland, away from the river. At [[Fishkill, New York|Fishkill]], the road passes the historic [[Van Wyck Homestead Museum]] and it becomes a six-lane divided strip until reaching the [[Poughkeepsie, New York|Poughkeepsie]] city limit. It then narrows to a four-lane divided strip which lasts until it intersects St. Andrews Road, just north of the [[Hyde Park, New York|Hyde Park]]–[[Poughkeepsie (town), New York|Poughkeepsie]] town line where it returns to two-lane status as it goes through Hyde Park and past its historic sites.

At [[Red Hook, New York|Red Hook]], US&nbsp;9 veers inland again, becoming a two-lane country road through [[Columbia County, New York|Columbia County]] save for the outskirts of [[Hudson, New York|Hudson]]. In [[Rensselaer County, New York|Rensselaer County]], it widens again as it intersects [[Interstate 90|I-90]] and then joins [[U.S. Route 20|US&nbsp;20]] to [[Albany, New York|Albany]], where it crosses the Hudson at the [[Dunn Memorial Bridge]]. It is a busy surface road through the state capital, becoming a strip in its northern suburbs and taking traffic eventually to [[Saratoga Springs, New York|Saratoga Springs]], [[Glens Falls, New York|Glens Falls]] and [[Lake George (village), New York|Lake George]], at the edge of the [[Adirondack Park]].

[[File:EndUS9.jpg|thumb|right|150px|End US&nbsp;9 sign just short of the Canadian border in Champlain, New York]]
The [[Adirondack Mountains|Adirondack]] section of US&nbsp;9 is the least trafficked of the road, returning to two lanes as it runs through vast tracts of forested wilderness and occasional hamlets. Almost {{Convert|100|mi|km}} to the north, it leaves the park and runs along or near [[Lake Champlain]] to [[Plattsburgh, New York|Plattsburgh]]. North of there, it is once again a two-lane road all the way to [[Champlain, New York|Champlain]], ending at an onramp to [[Interstate 87 (New York)|I-87]] just shy of the border.
