@chdot - you are right of course, CEC should be clearing the leaves off (main) cycle routes.
No idea why they haven't done so - it looks like more than 1 year's worth of build up.
It was my predawn ride out to the bridge last weekend that alerted me to how bad it was. Rather than bothering with the @west_team who I assume have already sent the ' Thanks for tweet we have passed this information on to the appropriate team to investigate.' tweet.
I couldn't remember where the very bad bits were, so we started at the bottom.
Perhaps some of the regulars could remind us and help elicit a response from CEC.
