https://www.bbc.co.uk/news/uk-england-bristol-21444841 is quite specific that the funding was based on the route going over the Prince Street bridge and that based on that, when George decided to reroute it away from there and up round Redcliffe Way, the government had to agree (as you can't secure money for one thing and then just change it).
"The city's elected mayor George Ferguson previously said he did not want buses running across Prince Street bridge or through the harbourside. But opponents of his plans said the city risked losing some £140m for transport projects.
The changes were agreed with transport minister Norman Baker following a meeting on Tuesday.
Mr Ferguson said a "number of potential improvements" would give a better connection on the route between Long Ashton and Temple Meads railway station. 'This helps burst the bubble of those who have been claiming that my appetite for changes to the route around the harbour would mean the Department for Transport withdrawing all the money,' Mayor Ferguson said. 'There are huge potential improvements to be gained in terms of route, vehicle and nature of the scheme with better connection to Temple Meads.'"
As regards "With the Bristol Parkway bit I think it was Travel West (Still Travel+) at the time not telling Network Rail of the plan, but Network Rail were fully aware of it never the less and chose to carry on anyway." - well, yes NR may have been aware but that's a world away from TravelWest engaging properly with them to sort access. After all, it's not incumbent for NR to approach authorities to improve bus access - it's the role of the transport authorities/operators who, in the case of Parkway, didn't get their ducks sorted!!
I fully agree that it should be replaced - I used to work in Avonmouth and go to the gym in Stoke Gifford and it was a pain to get through so it would massively benefit the area. I guess that NR look at it in terms of "Does the bridge enable the railway to run over it? Does it meet the loading and speed requirements for the line?" In that respect, that is why NR say it's fit for purpose. If it has bridge strikes, then the issue is with a) the LA to make sure that signage is good enough and b) the negligence of the individual driver. In short, NR are more bothered about their rails that go over it than the piece of tarmac below it
I know that the original plans (m2 and m5) and the later plan (m2) were to serve the SBLR - that was my point. Ill conceived in that respect, now covered by the fig leaf of "future proofing for planned development)
Fully agree - it would help some people move and that is hopefully what Marvin is on about. However, the biggest issue with buses everywhere is reliability - will they arrive when you want/need them to and that must involve removing them (as much as possible) from the congestion that blights Bristol and other major towns and cities. I go back to an earlier post about having better bus priority from Gilda Parade to Happy Landings to help buses. I guess the reasons it hasn't been done is the relatively low frequency on that section but you could do that and massively improve the cycling experience with no impact to commercial premises - just a thought!
