171
171 is a short route heading south from New Brunswick. 25M was designated before 1934 as the number for pre-1927 1 north of the split with post-1927 25, ending at the New Brunswick line where state maintenance ended (and still ends). In the 1953 renumbering, 25M became part of US 130, along with local streets to 27 in downtown New Brunswick. NJDOT truncated US 130 to US 1 in 1958 (or 1963?), and the road north of US 1, including the locally maintained section (inside New Brunswick), became 171. The routing of 171 inside New Brunswick changed at some point; instead of continuing on Commercial Ave to George St (former 18), and presumably turning there on old 18 to get to 27, 171 jogged left on Suydam St to what was once 26. In fact, an old 26 NORTH shield stands on what became 171 north. Around 2018-2019, the city-maintained portion of 171 was dropped and it now ends at the city line. History of the road is in the 25M entry.

172
172 is old 18 in New Brunswick. The original route of S28, which became 18 in the 1953 renumbering, entered New Brunswick from the south on George St, with state maintenance ending at Commercial Ave. Construction of a bypass along the river began in 1955, with Burnet St between George St and 27 being taken over and rebuilt by the state. At that time, the state-maintained part of the former alignment (to Commercial Ave) became 172. History of the road is in the S28 entry.

174
174 was the original number for the US 1 freeway north of Bus. US 1 near Trenton. The road was built in 1955 south of Whitehead Rd, and it was completed in 1973 to US 1. It remained 174 until 1/1/1988, when old US 1 from the Brunswick Circle exit to the end of the freeway became Bus. US 1, and 174 became part of US 1.

175
175 is old 29 near I-295 in the Trenton area, and now serves as a frontage road, as well as access for some movements of the 29/I-295 interchange. It was renumbered in 1963. The part of 175 in Trenton never became state-maintained. History of the road is in the 29 entry.

177
177 was Bridge St in southern Somerville, old US 206 (or maybe only old pre-GR 31). From information submitted by Myles Putman, Bridge St was likely only taken over due to its realignment at the new US 206 bypass. NJDOT only maintained up until Bridge St rejoined its original alignment, a distance of 0.24 miles. Even though US 206 was realigned as early as 1930 (with the complete bypass open in 1936), only in 1961 did 177 appear in state logs, and it wasn't on the official map until 1970 (and off by 1974).

178
178 was a proposed freeway along the 53 corridor, from the unbuilt 24 freeway north of Morristown to I-80.

ROUTE NO. 178. Added by L.1967, c. 142, s. 1, repealed 1997, c.143, s.3.

179
179 is old US 202 from Lambertville to Ringoes. The mostly-freeway bypass of US 202 around Ringoes opened in 1965, with the freeway extension into Pennsylvania opening on 10/16/1974. At that point, the old route became 179. History of the road is at 29 (the old number north of Lambertville) and US 202 entries. Also, 179 west of 29 was S29 pre-GR after a state takeover of Bridge St.

ROUTE NO. . Beginning at Route 29 in the city of Lambertville and running in a westerly direction to the easterly end of the Delaware river bridge in the city of Lambertville, more particularly known as Bridge street and a portion of U.S. Route 202 in the city of Lambertville. L.1948, c. 407, p. 1613, s. 1.

180 was old 72 east of Manahawkin (bypassed 1968); it was turned over to the county (as CR 50) on 4/16/1980 in exchange for 35 south of the Seaside Heights bypass. History of the road is in the S40 entry. The scan at right, from a 1969 map, is provided by Scott Colbert. It appears that NJDOT originally proposed CR 680, but Ocean County uses some two-digit county route numbers.

182
182 is a short route connecting US 46 to 57 and old 24. In the 1927 numbering, 24 went from Phillipsburg to Newark via Morristown. The alignment near Hackettstown used the old Washington Turnpike via Pleasant Grove. S24 split from 24 at Penwell and went to Hackettstown. When the routes were renumbered in 1953, NJDOT abandoned the idea of ever building 24 via Pleasant Grove, and rerouted 24 via S24 to the south edge of Hackettstown, and then south to Schooleys Mountain on the originally planned route. The bit of S24 north of what was now 24 became 57.
On 10/9/1969, the routes were renumbered again. 24 was truncated to only go east of Hackettstown on county roads, and 57 was reassigned to state-maintained 24 west of Hackettstown. The road that had been 57 became 182, since 57 was planned to continue east as a bypass of Hackettstown. That bypass has died, but the 182 number remains. The entire route is multiplexed with CR 517.

185
185 is a short spur from 440 in Jersey City, opened 2/25/1988 (when 440 in the area was still 169). Only about 1/3 of the planned route has been built, and none of the proposed alternatives have yet to be accepted. The numbering for 185 is similar to 85, which was a freeway proposed in roughly the same corridor, but this is most likely a coincidence.

ROUTE NO. ----. A northerly spur, wholly within Jersey City, Hudson county, beginning in the vicinity of Harbor drive and proceeding in a northerly direction to a connection with Bayview avenue. L.1976, c. 52, s. 1, eff. July 22, 1976.

I-195
I-195 runs east from the Trenton area. It was not part of the original Interstate plan. 37 and 38 were intended to be freeways across central New Jersey, with 37 continuing northwest from its present terminus toward Trenton (where I-195 now begins), and 38 continuing northeast from the end of its divided highway (and its former terminus) toward Belmar (where I-195 now ends). Since neither of those routes had funding, but there was a need for a freeway corridor linking the Camden-Trenton area to the shore, Interstate funding was obtained and the compromise route of I-195 was built.

ROUTE NO. . Beginning in the vicinity of a major interchange of State Highway Routes Nos. 29 and 206, in the township of Hamilton, county of Mercer, and thence in a generally easterly direction to an intersection east of Route 130 with the State highway route described in chapter 111, laws of 1953, approved April 22, 1953. L.1965, c. 210, s. 1.

US 202
US 202 runs southwest-northeast through the northwest part of the state. It was formed in the mid-1930s as a renumbering and extension of US 122 (connecting with US 202 from Maine southward once New York agreed to sign it). Before the GR, US 202 used pieces of 29, 30 (the current multiplex with 31), and 31 (the current multiplex with US 206), all of 32, and a piece of 23, as well as county roads from there north. The history of US 202 prior to 1953 is contained in all of the links in this paragraph.
Lambertville and Ringoes were bypassed by a freeway on 10/16/1974; the old route became 179. Around that same time, NJDOT boring logs show a potential relocation of US 202 from I-287 all the way into downtown Lincoln Park that suggest it would have been taken over by the state, following the path of the Morris Canal. This was likely killed for environmental reasons, but even decades after its designation, US 202 was still under consideration for upgrade from county maintenance.

ROUTE NO. . Beginning at Route 29 in the city of Lambertville and running in a westerly direction to the easterly end of the Delaware river bridge in the city of Lambertville, more particularly known as Bridge street and a portion of U.S. Route 202 in the city of Lambertville.

ROUTE NO. ----. Beginning in the vicinity of a new bridge to be constructed across the Delaware river, north of Lambertville, New Jersey, and running thence in a general northeasterly direction to a point in existing Route 202 (1953), north and east of Lambertville, New Jersey.

US 206
US 206 runs north-south through the state. It was designated in the mid-1930s along 39 south of White Horse, 37 from White Horse to Trenton, 27 from Trenton to Princeton, 31 from Princeton to Newton, and S31 north of Newton. Branchville was bypassed in 1941; prior to that US 206 and S31 used Broad St and Main St. Columbus was bypassed in 1957, and the old route became 170 (now CR 690). Netcong was bypassed in 1973, and the old route became 183. The short freeway west of Netcong is the only piece of the proposed US 206 freeway to be built, along a heavily traveled corridor in North Jersey that also is unfortunately getting too developed to continue building the much needed freeway. Plans for a smaller-scale Sparta bypass were around into the 1970s based on NJDOT boring logs but came to nothing.

Bypass US 206 came into being when the first, central piece of the Hillsborough Bypass opened between Hillsborough Road and 514 to the east of existing US 206 in Hillsborough. The designation will exist until the southern and northern segments both open, at which point US 206 will be routed onto the bypass and the existing route will be given to the town.

208
208 is a freeway in northern New Jersey, upgraded bit by bit from a Jersey freeway so that now the only driveways are at the extreme eastern end, by 4. It was S4B pre-GR. At one time it was planned to connect with NY 208 via a proposed freeway, hence the number. The freeway would have followed the originally proposed S4B extension around the north side of Ramapo Lake and meeting what's now 511 (Greenwood Lake Tpk) east of Wanaque Reservoir. Before I-287 was completed north of Exit 47 in Montvale, 208 extended west from its current end at I-287 Exit 59 past Exit 58 (US 202), tying into Oakland Avenue on the way to Skyline Drive. A sign at the other end of Skyline Drive, erected probably in the 1950s, points down it to "ROUTE 208". That west extension of 208 was upgraded on the spot to I-287 in 8/91.

208: From Route 4 at Saddle River Road, via former Route S-4-B to Maple Avenue, Hawthorne.
