From my observations on travel into Bristol from the South West (B3130/A370), there's a large concrete viaduct at Ashton Gate which overshadows the Level Crossing into the Industrial Park, a couple of concrete troughs through where the old PW depot was, leading to the old swing bridge over the New Cut, which has been refurbished.
It will be interesting to see if the Bristol Metro-whatever has the same issues as the Cambridge on did/does...
A couple of images culled from local press...
Ashton Gate - the railway line is what's left of the Portishead branch line:

New Cut - the old swing bridge over the River Avon, the PW dept was in the area below the guided busway and to the right of the Cumberland Basin road:

To the left of the swing bridge in the second image was the run-round loop at the end of the Bristol Harbour Railway, which has obviously been cut back at this point.
According to a BBC report dated 20/06/17, FirstBus is the assigned operator for the Metro bus service.
