|Route outline (key)|
The B905 today is a short link to the north of Falkirk.
It starts at the eastern roundabout of M876 J1 where it meets the A8004 and A883. After crossing the River Carron it turns sharply right (left is an unclassified road which joins the westbound M876 offslip) and then heads east to the A9, which it crosses at traffic lights in Larbert.
On the far side it continues eastwards running parallel to the A88 until it reaches the B902, ending on this road at a roundabout. This second part east of the A9 is very suburban, being essentially a distributor road to the new developments around the north of Falkirk.
The section along King Street in Stenhousemuir was originally unclassified. This had become part of the B902 by 1932. Eventually – but not before than the 1970s – things changed at the eastern end of the road, with the B902 and B905 swapping routes for much of the distance.
