A329M slip road to join M4 Westbound

Reported via desktop in the Road surface (NH) category anonymously at 01:14, Fri 4 June 2021

Sent to National Highways less than a minute later. FixMyStreet ref: 2767495.

This slip road is single lane during roadworks. I travel this piece of road regularly when riding a blood bike for SERV OBN. There is a ridge across the lane which is getting progressively worse. The temporary speed limit has recently been increased to 60 mph. I am aware of this ridge and was doing approximately 45 mph but momentarily bounced out of the saddle due to the ridge. On two wheels at 60 mph there is a distinct possibility the ridge could cause a rider to lose control of his/her machine.
