The grating pictured below is being installed, I presume eventually across the entire road here:-https://goo.gl/maps/czAvdtoMbzB2 (https://goo.gl/maps/czAvdtoMbzB2)

The grating slots are 18mm wide. This is a popular road cycling route. To be fair, that 25C tyre was not inflated hard, but a 20 or 23 C tyre (which I don't have to hand) would, IMO jam in tight. Even droping a front wheel in without jamming could cause a crash Logged report with DCC Highways FS-Case-32122601.

They've specified the cover wrong. The slots are supposed to be perpendicular to the dirrection of travel for precisely the reason you have identified.

They certainly have. Locally I have to cope with several examples of dangerous and badly designed roads and junctions:
- chicanes, which encourage 'give way lottery' and don't have a bypass for cycles
- a new traffic light junction, completed only two years ago, without even something as basic as advanced stop lines for cycles
- a major road proposal to create a dangerous left turning lane and make an already difficult traffic light crossroads (again, no advance stop lines for cyclists) even more risky
My understanding is that design guidelines for vulnerable road users are advisory, so old fashioned highways departments such as that in DCC can continue to ignore them.

Until their first criminal negligence claim comes in.

I have been told the gratings will be changed. 'Matter was overlooked'
I found the manufacturers site. The E400 gratings will I presume be swapped out for E600's
Still not ideal but much better.

The chicane bypass idea is fundamentally flawed. All the examples around Oxon/Berks effectively deliver you into the path of the oncoming traffic negotiating the chicane.
-
Load ratings for manhole covers and drainage are D400 (public highway), E600 (heavy loads) and F900 (exceptionally heavy loads e.g. ports and airports). Alignment of drainage slots doesn't directly relate to load rating but slots tend to get smaller as load rating increases.

Absolutely - lower speed limits with cameras to enforce them (in the absence of any traffic policing) would be my preference.
