For the current B707 in Ayrshire, see B707.
The B707 was a cross-country B-road west of Edinburgh, in an area where road numbering has changed beyond recognition since classification in 1922.
It started on the A71 (now B7015) in Mid Calder and headed north. The New Town of Livingston did not exist back then and so the route was quite rural. After crossing the River Almond, the route was more or less straight as it passed through Pumperhston. At Uphall it reached the A8 (now A899) and multiplexed east along it for a short distance before continuing north through Ecclesmachan to Threemiletown where it crossed the A9 (now B9080) at another short multiplex. The B707 ended a mile or so further north on the B902 (now A904) just beyond Old Philipstoun.
Although the route survived untouched until at least 1927, by 1932 the southernmost section, between the A71 and A8, had been upgraded to Class I status, becoming the A767. The remainder retained Class II status but, given that it was now entirely north of the A8, it was given an 8-zone number, becoming the B8046. Following the construction of Livingston New Town the A767 was downgraded back to Class II status and became a southern extension of the B8046. As such the full original route of the ex-B707 is now reunited with the same number, albeit one with a partially out-of-zone number.
