|Route outline (key)|
On reaching Anstruther, the B9131 first crosses the A917 then makes a short loop through the conjoined village of Cellardyke before returning northwestwards to end on the same A-road.
In 1922 the road north of the A917 was numbered B944 whilst the loop through Anstruther was unclassified. By 1932 the B9131 had come into existence as the loop whilst the cross-peninsula road had been upgraded to become the A959.
The A959 was downgraded in the 1980s, along with a number of other roads in East Fife, and became a northerly extension of the B9131, giving our road its present route.
