Fermi Avenue Roundabout

My back wheel twitched there too this morning but I didn’t go down. It looked to me as if last night the highways authority patched the cracks that had been developing between the two lanes on the roundabout and have managed to leave some greasy deposit on the road just before the patches while doing that.

Have a look on the HarBUG website on the News & Links tab and then Reporting Problems:

Reporting Problems

You will find a link to Vale of White Horse D.C. street cleaning page where you can report this slippy patch.
If a repair is needed follow the link to the County Council’s street maintenance page.
If the patch in the Campus there is also an email address to Goodman who deal with Campus roads

I am currently finding lots of roundabouts slippy and some inclines (if sprinting hard out of the saddle).

I don’t think the problem is unique to the roundabout in question or related to the repair which happened a few days ago. I have read somewhere but cannot find it again that some councils along with salt put a water dispersant on the road which is slippery for cyclists. The time I have found the roads slippery does coincide with shortly after the salting started.
