NINETEEN SIXTY FOUR – PART 51
Somerton - An Unusual Arch Bridge
Michael L. Roach
As the railway heads east from passing through Somerton the double track main line describes a huge curve. Much of it is on an embankment giving good views of the fields below. At the far end of the curve the railway passes over B3153 road from Somerton to Castle Cary, about 1½ miles east of Somerton, on a severe skew of 62 degrees. Normally, and even on a skew arch, the arch springs from a vertical wall / abutment which is parallel to the road, rails or canal that the bridge is passing over. In this bridge the arch springs from a flat area on the top of the abutment and is only an estimated 6 feet (1.8 metres) wide but there are six of these individual arches side-by-side arranged in a sawtooth pattern along the top of the abutment wall. This is highly unusual and was probably chosen because of the severe skew; and I cannot recall seeing another one similar before. One advantage of this design would be that the centreing would be used six times immediately rather than once, and perhaps never used again. At the beginning of June 2025 Colin Burges spent the weekend in Somerset and took the time to visit “six arches” bridge and take a number of photos which are reproduced here. Many thanks Colin.

Class 165-166 sets are ideal for dealing with the heavy additional traffic generated by events such as this due to the number of wide doors and open saloon space immediately available to those boarding with large items of luggage etc.
