What type of bridge is associated with pedestrian access at Perth Amboy station?

The type of bridge associated with pedestrian access at Perth Amboy station is an elevated bridge. Elevated bridges are typically built above ground level and are designed to allow pedestrians to cross over busy roads, railways, or other obstacles without interrupting the flow of traffic below. This design is particularly useful in urban areas where space is limited and safety is a priority. At Perth Amboy station, the elevated bridge facilitates safe pedestrian access to the station while also keeping them separate from vehicular traffic, enhancing safety and improving the overall functionality of the transit system.

This contrasts with underpass bridges, which are designed for traveling beneath an obstruction, and suspension or steel bridges, which have different structural designs and purposes.
