|Route outline (key)|
It started on the A71 (now B7015) in Mid Calder and headed north. Livingston did not exist back then as it does now and the road's route was quite rural. At Uphall it reached the A8 (now A899) and multiplexed east along it for a short distance before continuing north to Threemiletown where it crossed the A9 (now B9080) at a short multiplex. The B707 ended a mile or so further north on the B902 (now A904).
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 entirely north of the A8, 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 ex-B707 is now reunited with the same number, albeit one with an out-of-zone number.
