Arden Roundabout is the junction of the A82 and the A818. It is the first major junction on the A82 north of the Glasgow urban area, and (before the construction of the Crianlarich Bypass) was the last roundabout for nearly 70 miles to the Ballachulish Roundabout. The roundabout connects the A818 which crosses the hill to Helensburgh on the A814 to the A82, and is a faster if slightly less direct route from Helensburgh into Glasgow than following the A814 through Dumbarton. There is a fourth arm to the roundabout, being a local access to the Arden House estate.
The roundabout probably dates from when this section of the A82 was improved sometime in the late 1970s or early 1980s. At that time, the road to Helensburgh was a lowly B road, being the B831, however with the substantial traffic flow that the road carries it was upgraded to be the A818 on 7th January 2005. It has also acquired an off-road cycle track alongside the road, which connects with the Loch Lomond Cycle route from Dumbarton north to Tarbet, along the A82.
