Route 109 begins at an intersection with County Route 633 in Cape May, heading to the northeast on Lafayette Street, a two-lane undivided road that is county-maintained and signed as a part of County Route 633, which itself extends past the southern terminus of Route 109 along Jackson Street and Perry Street to County Route 626 in West Cape May. The route passes through residential and commercial areas of Cape May, passing southeast of the terminus of the Cape May Seashore Lines railroad at the Cape May Welcome Center/Cape May Bus Terminal and intersecting the northern terminus of County Route 653. At the intersection with Sidney Avenue, Route 109 splits into a one-way pair that has two lanes in each direction, with the northbound direction following Sidney Avenue east before turning north on Washington Street and the southbound direction remaining on Lafayette Street. Along this pairing, northbound Route 109 intersects the northern terminus of County Route 622. A short distance later, Washington Street turns west to join Lafayette Street, ending the one-way pair, and the route heads north as a two-lane undivided road. It crosses a body of water onto an island in Lower Township. Here, the route becomes maintained by the New Jersey Department of Transportation and signed as Route 109, continuing north past several marinas and other resort businesses. The road briefly widens into a four-lane divided highway before the median ends and it crosses over the Cape May Canal on the Cape May County Veterans Memorial Bridge. Upon crossing the canal, Route 109 becomes a divided highway again and intersects County Route 621. From here, the road passes a mix of homes and businesses before intersecting the southern terminus of the Garden State Parkway at an at-grade intersection. At this point, the route turns to the west and becomes a two-lane undivided road and heads through woods and marshland with some residences. Route 109 heads into residential neighborhoods before it ends at an intersection with US 9, which continues north on the road past this intersection as well as west along Sandman Boulevard toward the Cape May–Lewes Ferry terminal. At this intersection, a jughandle provides access from northbound Route 109 to southbound US 9.
History
The road that is now Route 109 was built as part of the Cape May Turnpike, running from Cape May north to Cape May Courthouse. The road was legislated as a part of pre-1927 Route 14 in 1917, a route that was to run from Cape May to Egg Harbor City along what is now Route 109, US 9 and Route 50. In the 1927 New Jersey state highway renumbering, this portion of pre-1927 Route 14 became the southernmost part of Route 4, a route that was to run from Cape May north to the George Washington Bridge. By the 1940s, US 9 was extended south from Absecon to Cape May, running concurrent with Route 4. In the 1953 New Jersey state highway renumbering, which eliminated long concurrencies between U.S. and state routes, the Route 4 designation was dropped along this portion of road, leaving US 9 as the sole designation. The current high-level bridge over the Cape May Canal was built in 1960, replacing a wooden swing bridge built by the U.S. Government when the Cape May Canal was constructed during World War II. In 1972, US 9 was relocated from its southern terminus in Cape May to head west to its new southern terminus at the Cape May–Lewes Ferry terminal in North Cape May, with the former route into Cape May becoming Route 109. On November 7, 2009, the bridge carrying Route 109 over the Cape May Canal was named the Cape May County Veterans Memorial Bridge, honoring all veterans.
