The old Woodchurch secondary school was in Carr Bridge rd, behind the schools playing fields lay the Fender, to cross the Fender there was a bridge, the bridge was in direct line with the Railway bridge (arched brick construction) which led to a rough lane, the lane went up towards Noctorum/Oxton. Though that particular bridge wasn't ancient, i always understood it to be called Carr bridge, and i would have thought bridges get replaced at the same site as the years go by, the lane would have been a very old track.
I remember that bridge, Bert, as will Pinzgauer & doubtless several others. Here's a map showing it. (Little red 'x')
To throw something else in to the mix, keeping in line with name changes, I'm wondering if Fender was once known as Fenden,not much of a change, Fen, meaning, low land covered in water, wholly or partly, peaty alkaline soil, and Den, meaning in old English, Valley. Doesn't help with the river name changes i know.

I've looked at those slides on ebay quite a lot in the last few months. The one you show is part of a larger collection but I'm not convinced all of them are actually of Wirral as the seller states.
They came from a collection originally used by a local photographic society and date back to the early 1900's, but I can tell you for a fact that quite a few of the slides were wrongly re-labelled. Most of the good ones have sold now. I imagine that the main reason the bridge slide hasn't sold yet is simply because nobody knows for sure where it's supposed to be. It might be Wirral, but I don't recognise it myself.
The only place that bridge could be and I'm going off memory, its a big maybe, the bridge inside Arrowe Park that went across the Arrowe brook, it was at the end of the lane if you go in the park at the bottom of Arrowebrook Rd.

Here's another shot in the dark. How about some where over the Prenton Brook around Barnston. Wherever it is the trees will have grown abit, and the course of the brook now hidden by trees. Where A551 goes down into valley. That was the brook wasn't it ?
