Doesn't bode well for the rest of those bridges along that stretch.
If that one hasn't been maintained correctly there is no reason to think all the others back up to the one that carries Sykehouse road on NJC have been.

The obvious worry is what comes first road traffic or canal traffic.
I've got a feeling I know the answer.

In fact you can bet money they've all suffered the same lack of maintenace. The reduced level of routine maintenance that is the current norm is going to bite cart on the ass

Well if it fails completely as has been pointed out in TD's post the counter weight would fall back in an arc and actually completely block the road. So if CRT are thinking they are giving road traffic priority they are mistaken. It would be one hell of a job to raise it once it had fallen back. Imagine the impact of the counter weight falling back free fall. This is the one at Sykehouse Rd.

Fair point. I got the impression from Tony's post that some sort of lifting tackle was being used in place of the failed hanger to hold the bridge in the closed position ie usable by road vehicles. Maybe I got that wrong. Eta TD wrote this : "A 5 ton SWL Chain Block onto 6.5 ton SWL bow-shackles at the ends of webbing slings/strops passing round the hanger bar pivot pins on the side of the bridge deck, and over the ends of the counter-weight beams is at present serving as a temporary replacement for the hanger bar with the broken end fitting."

Will those responsible for the (alleged) lack of routine maintenance be prosecuted? How have they been able to get away with this (alleged lack of maintenance) for so long? Why have no inspectors from 'Health & Safety' inspected the maintenance performed? Surely all maintenance should be recorded on paper and/or computer? Where are these records, and who signed the work off?
In my job I put not just the day down the bus was filled with fuel, but the precise time (eg. today at 1540).
Will 'Health & Safety' be prosecuting themselves for not doing their job properly (if that is so) ?

You are missing the point, . . lift bridge component failures, like the one at Thorne and to identical or similar designs of bridges, are more of a danger to road traffic, both vehicular and pedestrian, than they are to canal traffic.

The only boats that could pass would be those with sufficient clearance. Which if my memory serves me correctly wont be many (If any!!). Whilst traffic could still pass.

Is it a similar topic to railway level crossings perhaps. Rail v Road is quite a level playing field. Road v canal isn't. Some major engineering has been carried out to remove level crossings on certain lines because they were dangerous. I wonder if there will be moves to eliminate moveable bridges in areas with high traffic density. Times change. I always wondered if it would be worth putting in some sort of caisson where you drop the boat down then motor to the other end then raise water again. With safety interlocks. Would slow the journey down but might make it more interesting Not sure about the feasibility.

I think if a counter weight of that size fell freely the whole structure would be destroyed, is its not designed or built to withstand the forces that would be involved.

The reduced level of routine maintenance that is the current norm is going to bite cart on the ass bite cart on the ass bite boaters on the ass with increased licence fees, increased BSS fees, increased mooring fees, increased insurance fees (as boating is becoming a dangerous, risk-fraught activity). I had to laugh today as in the latest Tillergraph magazine there's a picture of a boat going in a lock, and one of the paddles has been covered by a black bin liner - isn't that so typical?

In commercial carrying days on that section it would have been a different matter of course, they would have had to get their finger out but nowadays in the overall scheme of things it will be 'only' leisure boaters put to the trouble/danger of trying to avoid that bit.

From here: www.iims.org.uk/what-future-for-freight-on-the-uk-canal-network/"Potential traffics: As CRT’s Jon Horsfall points out to Canal Boat, the A&C Main Line runs for something like 40 miles parallel to the congested M62 and overloaded railway lines. There is sea freight from the Humber in both directions." "So when will we see actual cargo carried? Jon Horsfall tells Canal Boat that the first new traffic could be no more than 12 months away. Time will tell if this is the start of a revival of freight on the north eastern waterways."
