The current Glen Ridge, Bloomfield and Watsessing stations along the Montclair branch were all built in 1912 during a grade separation program by the Delaware, Lackawanna and Western Railroad.

[11] The word "Watsessing" is a Native American term that translates to "mouth of the creek".

The lot also contains permit spaces six days a week and free on Sundays, with a cost of $20 parking per quarter (three months).

This name soon gave way to Watsessing, and in 1865, the line was bought by the Morris and Essex Railroad, running through trains.

[7] Construction was completed on a 1.5 miles (2.4 km) long segment of the Montclair Branch from East Orange to Glen Ridge and was opened to rail service on November 15, 1912.

The project laid 91 pounds (41 kg) of track in addition to steel ties and stone ballast.

[17] The design of Watsessing Avenue's new station was difficult due to the limited right-of-way.

While making the separation, a new trench had to be dug, which included retaining walls that prevented moving the existing track alignment to delay railroad traffic.

The station depot was built over the railroad tracks with four concrete arches to support the building.

A four-inch (10 cm) ceiling was constructed on the arches, and the station was widened to take more volume of train service.

[19] On September 10, 2007, New Jersey Transit announced the canopies of the old station, then 95 years old, were to be restored and repaired.

When the construction was finished in October 2008, the station now served nearly 450 people daily on average.
