About Watchung, NJ

Watching, NJ intersects with NJ Route 22 for about a mile on its eastern flank. Again, a very commercial strip of the state highway.

It’s an interesting community, with a curvy, nookie feel – along with steep roads, etc. Sometimes slow travel is to be expected. It also briefly intersects with Route 78 to the north.

Below is the “encyclopedia” entry:

Watchung, New Jersey

Watchung is a borough in Somerset CountyNew Jersey, United States. As of the 2010 United States Census, the borough’s population was 5,801, reflecting an increase of 188 (+3.3%) from the 5,613 counted in the 2000 Census, which had in turn increased by 503 (+9.8%) from the 5,110 counted in the 1990 Census.


The name “Watchung” comes from the Lenni Lenape Native Americans, meaning “high hills” or from “watschu”, meaning “hill”.

George Washington surveyed the British troops in Perth Amboy, many miles away, from the first ridge of the Watchung Mountains. The eastern reach of these ridges is to the Oranges in the direction of Newark. The name “Washingtonville” was used in early times but was rejected as the name for the area by the United States Postal Service, which felt that the state already had too many places named Washington.

Watchung, from the 1900s, was a semi-rural small community of about 3,200 people in comparison with the relatively larger and urbaner communities of Plainfield and Somerville. The first mayor of the town was Henry Baldwin Macdonald, who served from 1926 to 1928. Even as late as the 1960s, it was common for residents to know one another by name, with very few residents moving in or out of the town. The 1967 Plainfield riots, however, caused an exodus of the large upper-middle class population from the nearby cities to move to the Watchung Hills area to communities such as Watchung, Warren Township, and Bridgewater Township.

Watchung was incorporated as a borough by an act of the New Jersey Legislature on May 23, 1926, from portions of North Plainfield Township (now Green Brook Township) based on the results of a referendum held on April 20, 1926.

In the wake of public fear that ensued after the 1938 radio broadcast of Orson Welles‘ The War of the Worlds, National Guard troops were stationed around the hills in Watchung, as told on the vinyl record recording of news reports of the day.

Notable figures who have lived in Watchung include Bobby ThomsonBilly Ard, and Carl Banks.

Historic places

Eaton House is a Watchung historic site that was owned by congressman Charles Aubrey Eaton and has been the residence of other notables over the years. Known also as the Sunbright Farm farmhouse, the home was damaged in April 2014 when it was hit by some of about a dozen trees that fell as a result of a likely microburst in a severe storm that rolled through the area.


According to the United States Census Bureau, the borough had a total area of 6.054 square miles (15.679 km), including 6.026 square miles (15.607 km) of land and 0.028 square miles (0.072 km) of water (0.46%).

Unincorporated communities, localities and place names located partially or completely within the borough include Washingtonville.

The borough borders Bernards TownshipBridgewater TownshipGreen Brook Township and Watchung in Somerset County; portions of Morris County; and Berkeley Heights in Union County.

The Stony Brook flows through Watchung borough, making its way from Warren Township to the Watchung Lake, then through the gorge in the first Watchung mountain and over the Wetumpka Falls, on its way to the Green Brook.

The borough is roughly a 25-minute drive from New York City and a 10-minute drive from Newark.
