Barloan Toll in Dumbarton has been an important junction on the road West from Glasgow for over 70 years. Until recently, it was just a single roundabout, but in 2009 a second roundabout (Lomondgate) opened half a mile to the west.
Barloan Toll Roundabout
The Roundabout at Barloan Toll marks the end of the Dumbarton Bypass and the start of the Alexandria Bypass, which was built many years later. The Dumbarton Bypass was the westernmost and last section of the Great Western Road improvement started in the mid-1920s. The Alexandria Bypass is about 50 years newer! Up until 2009 the roundabout was the junction between the dualled A82, the B830 into Dumbarton town centre, and the A813 (ex A82) into Alexandria. However, in 2008 a new roundabout, Lomondgate Roundabout, was constructed just under half a mile to the west, with the A813 diverted to that junction the ex A813 (ex A82!) is now an unclassified route serving the Bellsmyre Estate.
The roundabout itself is a simple 4-arm signalised junction, with the A82 being dualled either side and having three approach lanes, the other two roads just having the two approach lanes. To the south, the B830 almost immediately forks left at a TOTSO, which is actually a fiveways junction, with two service roads for the properties facing onto the A82. However, most traffic continues along the unclassified Townend Road.
History
Before the A82 was re-routed onto the Alexandria Bypass in the early 1970s, the junction here was more of a T Junction, albeit with the B830 and Townend Road splitting immediately after turning off the A82. This is likely to have been the case for centuries, since the roads were only muddy tracks, as Dumbarton was the county town, so routes would have radiated out across the county. By the 1950s, there is a suggestion on maps of a road leading into the Bellsmyre Housing Estate to the north, taking over the driveway to Aitken Bar Farm, although this has since been removed. The roundabout was almost certainly built as part of the bypass.
