I'll give it 10 years before that busway is closed down due to high
maintenance costs and bus operators no longer wanting to pay to use it
when they can use the roads for free.

I had a wander down it this afternoon. The concrete beam sides have small
gullies (about 1" across and deep) across the top surface, about 2 or 3 per
beam. There's already what looks like freeze-thaw weathering, to the extent
that pretty much every gully has a crack leading down, that's the height of
the beam side (about 8").

It may be this is a design 'feature', but it doesn't bode well. These beams
were only laid last year. A few look like they've been bodge-patched with
cement.

In other news, the busway has finally been signed off by the contractor.
Only 2.5 years late...
