The B812 is a short B-road in the northern suburbs of Glasgow. The road was originally unclassified but had gained its present number by 1932.
This road commences at a signalised junction with the A803 in the Colston area as Colston Road; from here it travels in an easterly direction, crossing a roundabout to become Auchinairn Road which presently meets the B765. The road continues through a number of roundabouts giving access to areas of relatively new housing and a link into the new Bishopbriggs relief road at Auchinairn Roundabout, which loosely provides a north eastern by-pass of Glasgow. The B812 then becomes Robroyston Road and heads into open countryside, sweeping north westwards through fields, to terminate at an awkward TOTSO junction with the B819 near to Loch Farm, Lenzie.
