This a channel running parallel to the direction of travel on the A590 in Cumbria just outside the entrance to Lakeside and Haverthwaite steam railway.
It is a design and construction issue, not a Highways Act failure to maintain. Unsurprisingly the bike stopped dead, the rider sustained a comminuted fracture to his clavicle and Highways England paid for the surgery, consequential losses and damages for pain, suffering and loss of amenity.
The bike in the pic belonged to the Cycle-Aid investigator. Always good to have one handy.
