[5] Passengers can also use a signalized and gated grade crossing (across the southbound track) between the parking lot on Dubuque Avenue and the north end of the platform.

A tall metal staircase descends to the parking lot from the Grand Avenue overpass at the intersection with Dubuque, though the more direct pedestrian underpass has obviated the need for passengers to use it.

[6] The south end of the parking lot features a large mural on the retaining wall for Grand Avenue entitled Prometheus Brings Fire to Man by artist Nicolai Larsen, painted in 1996.

[3][4] The previous station was built before the Bayshore Freeway[7] and retained many of the aspects common to older, unmodernized stations along the Peninsula Commute: the platforms were not accessible-compliant, and riders seeking to board a northbound train had to wait for the train to come to a complete stop before crossing the southbound track to a narrow boarding platform between the tracks.

[5] The planned west entrance also featured a new pedestrian plaza at the southeast corner of Airport Boulevard and Grand Avenue, on right-of-way previously used as a Caltrans storage yard.

[22] Although construction was scheduled to begin in 2016,[23] the design was not finalized until December 2016,[5] and groundbreaking for the modernization project was held on November 6, 2017 in a ceremony attended by State Senator Jerry Hill and South San Francisco Mayor Pradeep Gupta.

[22] The new station was projected to open in 2019,[5][23] but was delayed to August 2020 after planned underground utility relocation work was determined to be a prerequisite for construction of the new pedestrian underpass.
