November 24th – On the way back from Chasewater to Brownhills on yet another dull, wet Sunday afternoon following a frankly disappointing winter fair at Chasewater, I wasn’t expecting to find much: But I found something fascinating that’s been staring me in the face for decades and I have never once noticed.
It’s fairly well known that when Abraham Darby bullt the Iron Bridge over the Severn at Coalbrookdale, iron was such a new material that many of the jointing techniques used were adapted from carpentery, as that was the understood skillset of the day.
I noticed for the first time today that the Ogley foorbridge over the cut off stub of the Lichfield branch of the Wyrley and Essington canal – recently refurbished – holds it’s guard sides together with a neat, well fitted dovetail joint in cast iron.
The bridge, dating from around 1850 is a listed structure, and I’m beginning to see why. The rails are constructed in two half-crescents with a dovetail centrally, held rigid by a bolted mating sleeve.
It’s utterly beautiful and means the bridge is thoroughly rigid.
I only noticed due to the rust bleed into the ageing paint.
You can always find something, no matter how grim the weather…
