A year and a half after the Expo Line finally brought rail service back to the Westside, Culver City is up to its ears in transit oriented developments. Earlier this week, heavy equipment and sidewalk scaffolding showed up at the abandoned used car dealership across the street from Culver City Station. It looks like the Runyon Group’s highly anticipated mixed-use complex, known as “The Platform,” is finally starting construction. The project, designed by Abramson Teiger Architects, will create ample retail, restaurant and office space just east of Downtown Culver City. It should provide a nice complement to Access Culver City, which broke ground in October.
