August 22: I is for Ironbridge.

Ironbridge: the name says it. All those glorious structures like the Forth Bridge, Sydney Harbour, the Howrah, the Golden Gate and the bridge at Victoria Falls, owe their ancestry to this iron bridge over the Severn in Shropshire.

A bold venture to build a bridge of cast iron so high above the river in 1779. The beams were cast on site since transporting them would have been difficult. But would it work? Abraham Darby must have been an excellent mathematician, blessed with patience to check each step of his calculations and each stage of the casting, the building of foundations and assembly of the bridge. Here it stands today, carefully maintained, like the Forth Bridge and all those others. My grandfather, a Shropshire lad, took me to see it aged about five; it impresses me more now than it did then, unlike so many things.

Crossing the river here safely was a dream made real by Darby and the men who dug his coal, smelted, transported and cast his iron; masons, surveyors, painters. He and they had to trust in the laws of physics as they understood them. The people who keep the bridge alive –  it is still open to pedestrians – apply the physics and chemistry they understand to prevent rust, metal fatigue and erosion.

The dirt and hard labour of the Industrial Revolution have gone, leaving the Severn Gorge free from dark Satanic Mills. But if we are to build Jerusalem in England’s green and pleasant land we need an understanding of what we are about, and how to ensure dirt, fatigue, rust and erosion do not stop us working together.

God, come to our aid, Lord, make haste to help us!

Laudaato Si’!
