Precast concrete
The most interesting part of the station was the upper bus deck. The deck was constructed of precast concrete that was formed off site, which was then transported to the site before being placed atop columns constructed as part of the stations foundations. Precast concrete flooring was then put in place, held in specially formed ridges running the length of the beams. This upper deck was the most expensive structural element of the station, and was the cause of significant attention and consideration as part of the design and construction process.
