This morning's commute and other commuting stories

Used the cycle lanes at E&C today, could anyone explain to me why the cycle lanes are so bumpy compared to the road? Is it something to do with not being able to drive a big enough roller over when they tarmac it? Feeling a bit seasick/10

I haven't used them except very briefly once so don't really know what they're like, but I hope they haven't hand-rolled the tarmac. It's always been a limitation of laying non-standard carriageway widths that the normal machines can't be driven over them (too wide, obviously), but I would have expected that they would at least have purchased a few narrower machines for such large projects. They do exist; I heard a few years ago that there was at least one in London that could be hired. That said, hand-rolling normally produces a very wavy surface that wouldn't really have passed muster in any event, so it may be due to a completely different issue.
