The station, opened on September 6, 1910, has two tracks and one island platform. Originally the station had exits at either end. The western stair led to the intersection of Grove Street and Newark Avenue and a simple kiosk underneath the Pennsylvania Railroad's mainline viaduct, which ran above what is now Christopher Columbus Drive. The station's easterly end exited to Henderson Street. The railroad viaduct was taken down in the late 1960s, and the station was reconfigured in the 1970s. As part of the reconstruction, the eastern and western exits were closed in favor of a mezzanine situated in a triangle formed by the intersections of Grove Street, Newark Avenue, and Columbus Drive. Two stairways from the platform level connect to the mezzanine, with fare turnstiles at the top of each stairway. Two exits lead to street level; one, with escalators, leads to the station's primary kiosk, while the other is a stairway that leads to the south side of Columbus Drive. As a result of an increase in ridership, the Port Authority of New York and New Jersey reopened the easterly exit and built a second kiosk at the corner of Columbus Drive and Marín Boulevard. Despite the fact that construction of eastern entrance/exit took place between 2003–2005, the station was not made compliant with the Americans with Disabilities Act of 1990. In September 2011 a federal judge found that it was technically feasible to do so and ordered the PANYNJ provide handicapped-access. In 2014 legal settlement the PANYNJ agreed to provide handicap at the western end of the station. Construction of elevator access began in April 2015, and the elevator opened in June 2017. However, a month after opening, it experienced several breakdowns. In June 2019, the Port Authority released the PATH Improvement Plan. As part of the plan, every train on the NWK-WTC route will consist of 9-car trains. To accomplish this, the platform at Grove Street will be extended at the Marin Boulevard end of the station. The platform extension is expected to be completed by 2022. The Port Authority put the contract to extend the platform out to bid on January 28, 2020, and expected the cost of the project to be between $15 and $20 million. To extend the platform, structural walls will be replaced by support columns. The intersection is a busy stop for buses, most of which head west and south.
