I'm standing in downtown Sacramento looking across the river at the I Street Bridge, the CalSTRS Building, and the Sacramento Pyramid (or Ziggurat).
This double-deck swing bridge carries two sets of railroad tracks on the bottom deck and motor vehicles (and pedestrians) on the top deck. The swing mechanism is still very active. The bridge was built by the American Bridge Company in 1912 and its currently owned by Union Pacific.
