Spring Coppice Aqueduct at Shelmore embankment
It's a quality structure, with a lofty barrel arch and dressed stone portals. The aqueduct carries a busy but narrow country lane and can be easily found if you listen out for regular car horn tooting, as vehicles approach it's blind entrances. Mooring to take a look as this structure is problematic, given the incredibly shallow margins in the area. The only realistic way of stopping is to hover in the narrows which contains the flood control gate, and hope no other boats arrive. I was lucky - I had the place to myself but was amused to see a narrowboat steam round the corner from Norbury just as I got underway again!
