The bridge cables are in an unusual fan arrangement with five cables attached to special anchors at the ends of the back spans. Perhaps the extra cables are needed to balance the long main span? At the top of the towers the cables are attached to diaphragms between the pylons. The girders on the approaches look very deep (or the girders on the cable-stayed bridge look very small).
On the Buckland and Taylor Website, they mentioned that they were underbid by 0.5% on the project but later came in to evaluate whether the bridge was capable of carrying heavier trains. Information on this bridge is limited but I noticed that some websites say the bridge was completed in 1986 (in time for Expo86) while others say the bridge wasn't completed until 1990. Also I saw a couple of reports stating that chunks of concrete were falling from the bridge but that the bridge owner (Translink) assured reporters that there was no cause for alarm.
