This is a rendentaton of the new bridge. Unlike many steel arch bridges that are tied arches, this bridge is a true-arch bridge.

The anchorages are socketed 4m into bedrock. [McIntoshPerry]

The 1949 deck-truss bridge replaced this through-truss bridge.

A temporary (a few years) bridge was shoved over the river.

I thought we lost just a UCEB (Ugly Concrete Eyesore Bridge), but I see the old bridge was a deck truss.

A big lattice-boom mobile crane was used to lift each of the 120-ton arches into place.

Normally, concrete is poured from one end to the other. In this case, they poured from both ends to keep the load on the arches balanced. Note the use of two concrete pump trucks.

A comment on the video questioned the expense of a temporary bridge. That question makes sense to me given that they had to acquire the land for an alternate route anyhow.
