This archway was created as a showpiece for the Home For The Poor of Bioshock2. The concept behind this was a grand, but run down, entrance to the metro. You can see players moving around it here in the multiplayer trailer at Gametrailers.
In production of this map there were a large number of modular pieces (made by 2k Boston) assembled to form archways. To reduce the static mesh count from 384 to 16 I had to quickly rebuild the arch and match the exact footprint the original pieces took. The below picture illustrates the affected area.
