40434 is on the first of two Stamford Roads it will traverse in the course of this journey which is technically a 344, as it is following the route of that service. Seen in Hey at the bottom of Den Lane, it was diverted that way due to road resurfacing on Lees Road in Clarksfield. The diversion ended up in operation on a few more Sundays than anticipated due to quality problems with the first two attempts.
