|Route outline (key)|
The A806 runs on largely new alignment in the Central Belt.
Starting at a signalised T-junction on the A803 Kirkintilloch bypass the road runs south through a cutting and into town. It runs along a relief road past the town centre and over the Forth & Clyde Canal before meeting the first of a number of roundabouts on the route. Continuing south through the suburbs, another couple of roundabouts are met and the road goes under the Glasgow to Falkirk railway line. The route itself is following the line of the old Strathkelvin branch line. After following a dead-straight route through open country (partly in a cutting), another roundabout leads to the M80 at Hornshill Junction, J3.
Beyond the roundabout, the A806 becomes dual carriageway, initially following the westbound carriageway. As the road bears round to the right, it picks up the old eastbound carriageway as well and ends soon afterwards at a roundabout on the A80. To emphasise this section of the road's origin as part of the M80, the road gains hard shoulders just before it ends.
In December 2010, construction of the Kirkintilloch Link Road extended the short A8006 and the new route was designated as the A806. Although the new section of road from the B8048 to the M80 was officially opened on the 28th November 2010, it remained closed until the 1st December 2010 due to heavy snowfall repeatedly obscuring road markings and signposts.
Upon completion of the M80 offline upgrade the following year, the route from Hornshill to Crowwood Roundabout at Stepps (which was originally M80) also became part of the A806, giving the road its current route.
The Glasgow Local Plan also includes the Easterhouse Regeneration Route which would continue from the southern end of this route at Crowwood roundabout through to the Glasgow Fort complex at J10 of the M8 - this road may form a further extension of the A806.
