A40 OVER BRIDGE: PROGRESS REPORT 20th August
First, the thing I said I would do. On 23 July I told you I would meet National Highways on 12 August and report back.
That meeting has not happened. National Highways were not able to meet during August and we are now working towards a date in September. Rather than let the questions sit waiting for a diary, I put them in writing on 10 August instead: seven specific requests, with a deadline of Friday 21 August. I will report what comes back, and I will report it if nothing does.
Since then National Highways has sent stakeholders its first monthly progress report on the works. Here is what it says, what it does not say, and what I am still pushing for.
Where the works have got to
All traffic has been running on the westbound side of the bridge since Monday 28 July, one lane each way, 24 hours a day. Getting to that point meant tracing and protecting underground services, taking out the central barrier, lighting and drainage, digging the crossover points, laying new drainage and ducting, and rebuilding and resurfacing the carriageway. Underneath the bridge, specialist teams have hung a scaffold platform so repair crews can reach the parts that cannot be touched from the road, with a safety boat on the water while it went up.
National Highways says the scheme remains on programme for completion in March 2027.
What happens during August
Crews will strip the road surface and the waterproofing off the eastbound deck to expose the concrete underneath, then start repairing it. At the same time, repairs to the deteriorated concrete beneath the bridge will be carried out from that scaffold.
Why the site sometimes looks empty
I set this out in July after putting the question to National Highways. It now appears in their own written words, which matters, because a commitment in writing is one you can hold them to.
Concrete repairs have to be done in stages, and each one needs roughly 24 hours to set before anything else can happen around it. While it is setting, vibration from traffic, machinery and construction has to be kept to a minimum, or the repair will not reach the strength it needs. So there are stretches where very little appears to be going on above your head, by design rather than by accident. The shifts are also split: noisy work on the deck at one time of day, scaffolders working underneath at another.
I accept that argument. Putting more people on site does not make concrete cure faster. It is worth saying plainly, because a nine month job that looks idle breeds a lot of understandable anger. What I will keep checking is that quiet spells are curing time and not the programme slipping, and for that I need their detailed works programme, which I have now asked for three times.
Traffic
National Highways says conditions were difficult in the first weeks and have generally improved since the contraflow went in. That is their assessment, not a measurement, and there is not a single journey time figure in the report.
It is also worth noticing when that assessment was made. Schools broke up on 20 July. The contraflow went live on 28 July. Every day of it so far has been school holiday traffic, in August, when a good share of the county is away. The works have not yet seen a single day of term time. I will come back to that in a separate post before schools go back.
In July National Highways agreed in writing to share their traffic sensor data with me and to review their published delay figures. I have asked for that data from 28 July onwards, broken down by time of day and by direction, because an average tells you nothing useful if you are deciding when to leave for a 7am shift. When I have it, I will publish what it shows, whether or not it matches what you and I expect.
What I am still chasing
The detailed works programme with milestones, so that "on time" is something anyone can check rather than something we are asked to take on trust. Honest published delay figures rather than an average. A proper written response to Lydbrook Parish Council about traffic pushed onto our village roads, which was raised formally on 13 July and has still not been answered. And confirmation of the date in October when the contraflow switches over to the other side.
If you work shifts
Almost everything National Highways publishes is built around rush hour. Plenty of Foresters at the hospital, in the police and in other shift work are on that road at 5am or after 8pm, outside every peak they measure. If that is you and the works are affecting you, please tell me. I am raising it with them directly and first hand accounts carry far more weight than my opinion does.
Reporting problems
National Highways can be reached on 0300 123 5000. You can also contact me and I will put it to their route manager.
Nine months is a long haul. I will keep reporting back honestly, including when the answer is one we would rather not hear.
