Further north, after passing Loch Lomond, the predecessors of the modern A82 can be easy to trace in the surrounding Landscape. The Military Roads dating from the early-mid 18th Century, and the replacement road built by Thomas Telford in the early years of the 19th century are either still in use, or left to slowly sink into the land. However, at the roads start, in the heart of Glasgow city centre, there is no hope of finding such evidence with any ease. The Military Road network is known to have extended to Dumbarton Castle, while Telford's road is described as starting in Glasgow itself, but 200 years of further development have destroyed all trace on the surface.
As a result, for this section of the road only, we shall have to start in 1922 when the A82 number was first allocated, to a drastically different route to the one we travel today.
In 1922, the Great Western Road barely extended beyond Anniesland Cross, so the original route of the A82 seems to have followed Argyle Street and/or Bath Street out of the city centre, to pick up the route of todays A814. With the odd exception for realignment when the Clydeside Expressway was built, the original route of the A82 followed the present route of the A814 all the way west to Dumbarton.
At the time, Great Western Road itself was given the B810 number, later to be renumbered as the A876 as it was extended westwards to Dumbarton. In Dumbarton town, it seems to have originally followed the route of the modern A812 and B857 to Balloch.
In 1927, the Great Western Road was more or less complete, providing a new, wide highway from central Glasgow out to Dumbarton. However, when it was opened it was numbered as the A876, with a spur to the A82 at Old Kilpatrick given the A878 number. These numbers had not been allocated back in 1922, and were being used up in sequence at various places around Zone 8. Compared to the narrow Urban route that the original A82 followed, the new A876 must have been a fast, empty highway used primarily by Motorised vehicles once past Anniesland Cross, so it is little wonder that it became the new route of the A82 out of Glasgow in 1935.
This saw the A876 number temporarily retired for future use elsewhere, and the A814 extended from its Arrochar - Dumbarton route all the way into Glasgow City Centre, along the route that it still takes (give or take the odd bit of dualling!). The A878 number, however, still applies to the short spur at Old Kilpatrick, it's sliproads mingling with those for the A898, but not allowing any traffic flow between the two routes.
It would be easy to say that nothing has changed since the A82 was rerouted along the Great Western Road in 1935. However, as is true with any major route in a city, the changes are substantial.
To start with, as we have seen above, the A82 once ran into the heart of the city. Today, it starts on the M8 at the nightmarish Junction 17/18, part of the Charing Cross Interchanges. As such, the first bit of the current route is new, having been built in the 1970's along with the motorway. Soon, however, we are deposited at the Start of the Great Western Road, and head north west along a route that fluctuates between S2 and S4, with the inside lanes blocked by parking and bus stops. The River Kelvin is crossed by the Great Western Bridge (see below), and then after about two miles we reach the confused junction with the A739 at Anniesland Cross. This gives the first opportunity to cross the River since we left the Motorway, by heading south through the Clyde Tunnel.
The road then becomes D3, with intermittent bus stops, but at least this allows two lanes of moving traffic in each direction through Drumchapel (with a lane drop through the Duntreath GSJ) and onto the B8055, Drumry Road Roundabout at Clydebank. Westbound traffic has a lane drop just before the roundabout, while eastbound leaves the roundabout with three lanes. Curiously, however, the overall width of the roadway remains at just over 30m, with a central reservation of a little over 11m. This would suggest that the eastern D3 section has been created by narrowing the traffic lanes, rather than widening the road, so the D2 section could theoretically also become D3!
The next junction is the Kilbowie Roundabout with the A8014 and B814. Just under a mile later, the A810 meets the eastbound traffic, westbound traffic can access the road via the A8014. There is then a GSJ with Mountblow Road before the complex Old Kilpatrick Interchange, where the A898, Erskine Bridge road crosses the Clyde, and the A878 provides limited access to the A814. Beyond the interchange, the character of the A82 changes. Gone is the wide, grassy central reservation, replaced with a kerbed central barrier. The speed limit drops to 40 and the road becomes narrower once more. If it wasn't for the existence of the A878 and the knowledge that the A814 was extended into Glasgow City Centre in 1935, it could be believed that this section of road was later. In addition, the 1933 Bartholomews map (left) shows both routes running in parallel. Perhaps the dualling is later, the road having been built as a standard two-way road.
As we pass through Bowling, the A82 gets much closer to the Clyde, with the A814 running parallel on the left for a time, before finally running out of land and joining the A82 for a brief multiplex through Milton. In 1935, the route beyond the A814 fork would have been the edge of Dumbarton, if not beyond, but it now slices through the housing estates on the towns northern side. However, the narrow section of the D2 is nearly over, with the roundabout at Barloan Toll marking the end of the original Great Western Road, and the start of the Alexandria Bypass, built in the 1970s.
After the long haul out of Glasgow, we finally reach Alexandria. However, the modern bypass was built in the 1970s and before that the routing of the A82, A811, A812 and A813 seems to have changed several times. Here's an attempt at describing the changes:
In 1922, the A82 entered Dumbarton on the current A814, before turning north on the A812 and B857 to Balloch. So far, so good. However, the other routes get a little more confused. To start with, the A811 is quoted as starting to the east of Dumbarton, and then following the current A813 north to join its modern route. As the Dumbarton Bypass had not yet been built, it is possible that the B830 qualifies as 'east of Dumbarton'. This certainly seems to be the only surviving option, unless the bypass was constructed along the route of an existing road.
The changes in 1935 were sparked by the re-routing of the A82, with the construction of the Dumbarton Bypass. The A82 therefore picked up the former A811, modern A813 route north along Stirling Road, before crossing the River Leven on the former A812, Bonhill Bridge to resume its original route. The A812 number was then reused for the ex-A82 setcion between Dumbarton and Bonhill (the A814 extended through Dumbarton and on to Glasgow). This slightly foreshortened the A811 and left the A813 where it was.
The southern section of the Alexandria Bypass was opened in 1972/3, and the A82 number immediately transferred to the new dual carriageway. However, with the western section still under construction, the A82 then had to return to its old route through Renton, which had been the A812, and is now the B857. This saw the A812 truncated to its current stubby length. When the western section of the bypass opened a few years later, the A82 was obviously routed along it, with its former route downgraded to the B857. With the new roundabout at Balloch, and further upgrades to the north, the A811 was also rerouted to meet the Balloch Roundabout, and so take through traffic away from Jamestown and Bonhill. The two routes essentially swapped numbers, with the old A811 becoming the current A813.
In no particular order, there have been several minor realignments to this road network (irrespective of which number they carried!) in the last fifty years.
- The A814 now passes to the north of Dumbarton Town Centre.
- The A811 follows a new route, to the south of the old Balloch Road.
- The B857 appears to have been moved to the east in Alexandria.
- The A813 has also been moved eastwards in Bonhill, and has been moved westwards at the northern end.
Great Western Bridge
The Great Western Bridge was opened on 29th September 1891, to carry the Great Western Road across the River Kelvin. It still does that job today. The river is crossed with two green-painted metal spans, separated by a stone abutment, dressed with a pseudo-classical column on the outer face. At the western end, a minor arch carries the road across a riverside walkway.

Not strictly on the A82, but the Erskine Bridge (right) on the A898 is an integral part of the route nevertheless, bringing traffic across the Clyde from the M8, and so marking the point where the A82 becomes primary for the rest of its journey north.
Main Article: Dumbarton Bridge
Part of the A82 route from 1922-1935, the old bridge at Dumbarton has since been replaced on the A814 route, with the A82 itself now using a new bridge to the north of the town.
The old bridge at Bonhill was replaced with this bow-string structure in 1987. The first bridge here was built in 1836, to replace a ferry, and was a small suspension bridge. It was locally known as the 'Bawbee Bridge', with Bawbee being local dialect for Halfpenny - the toll charged. It was replaced in 1898 by a steel arch girder bridge, but this was still narrow and it appears to have been a reluctant decision to re-route the A82 across it in 1935. Ironically, the modern bridge is plenty wide enough!

Again, not ever part of the A82 route, but an integral part of the transport network in and around Alexandria.
