Yes, although you're assuming that the quakes which constitute the movement of the fault are small.
Seriously though, any structure spanning a moving fault is going to have issues over time. The Kobe earthquake struck during the construction of the Akashi Kaikyou bridge, and the two sides ended up shifted a metre further apart. Fortunately the design was able to cope with the change, and the deck hadn't been built at the time.
