Some of the stations have no space. Smith/9th St is positioned over the road with a concrete plant behind it. Every station is different and most of them can be updated with the elevators or ramps, but some are just super difficult because of their design or how they are positioned in relation with the street above or below. It’s also incredibly expensive and takes forever to coordinate with adjacent owners and related agencies, especially when excavation is needed.
