Covered with ivy for many years this Ordnance Survey rivet benchmark has just re-appeared as the bridge has now been tidied up and a lot of the ivy has been removed. It is recorded on the 1888-1913 map as levelled at 315 feet above Liverpool Datum. For a wider view see Image Benchmark Database: https://www.bench-marks.org.uk/bm203154
