M80

The M80 is a motorway in Scotland linking Glasgow with Stirling. It was formerly in two sections, the Stepps Bypass at the southern end, and the Haggs - Stirling section at the northern end, linked by a section of A80. This section of A80 was upgraded to M80, opening in late summer 2011.

Route

The motorway starts on the M8 in Glasgow at Junction 13.

Whilst the M8 continues to the northeast we head almost due north for a very short stretch before swinging to the east as we pass under a railway bridge (which always seems quite low!). We run alongside the railway for a very brief stretch before heading more northeasterly to Junction 2 at Robroyston.

At this point we are still in the 50MPH section, which ends roughly half way before we reach Junction 3 - Hornshill. This used to be where the southern stretch of the motorway ended, with a sharp turn to the right ending at a roundabout on the A80. As part of the final completion of the M80 in 2011, this was converted to a standard roundabout, in the process doing away with the right hand entry to the Motorway that used to exist.

From Hornshill we run along the new build part of the motorway, bypassing Chryston and Moodiesburn to the north. Previously all traffic took the A80 through both of these, with another 50MPH section, traffic lights and a few speed cameras.

We rejoin the original route of the road (but now upgraded to motorway) at an almost completely rebuilt Junction 4, which now allows freeflow to / from the M73 (but only heading to / from the northeasterly section of the M80 - there wouldn't be much point in heading south on the M73 as you would have just kept going on the M8 eastbound instead.

From here to J4A the northbound section of the road is 4 lanes, but be careful as the left hand two swing off to join the A8011 Cumbernauld Ring Road.

Now we come to Junction 5 - Auchenkilns. After leaving Auchenkilns behind we climb up to Old Inns (Junction 6) before dropping down the other side to Castlecary (Junction 6A) and Haggs (Junction 7).

Between Old Inns and Castlecary, the Castlecary viaduct carries the main Glasgow - Edinburgh rail line over the motorway. Its arches are too small to allow two lanes plus a hard shoulder through, so when this bit of the road was rebuilt the hard shoulders were each routed through a separate arch to their respective carriageway.

From Castlecary to Junction 8, Bankhead, northbound, and from Bankhead to Old Inns, southbound, the motorway is three lanes wide, although lane 1 is more often than not treated as a slip road for the various junctions, and so doesn't provide as much capacity as it could.

In the middle of this section, at Haggs, we pass through the original start / end of the northest section of the motorway, from Haggs to the M9 at Junction 9, Pirnhall.

At Bankhead the M876 leaves to head east to the River Forth and the Kincardine Bridge via the M9, and from there to the end of the motorway, we are back to two lanes wide again.

At Bankhead (and Pirnhall later) the slip road for the junction bears left, and then swings back to the right, while the main carriageway swings left and climbs over it. There is a short uphill stretch before we swing slightly right and drop downhill bypassing Denny on our right.

After Denny there are some sweeping curves and some short straights before we reach Junction 9, Pirnhall, where the layout of the Junction is similar to Bankhead.

After passing Stirling services to the right (but down below so not really visible) we then reach the junction with the M9 where the motorway ends.

Junctions

Hornshill Junction

Main Article: Hornshill Junction

Hornshill Junction is junction 3 of the M80. It previously linked to the B757, and the M80 also stopped here, turning through a sharp turn to join the A80 and featuring a right-hand entry to the motorway. As part of the M80 completion works, it was converted to a standard roundabout and now links to the A806.

Auchenkilns Junction

Main Article: Auchenkilns Junction

Auchenkilns Junction is a junction found on the A80 in the detached area of Dunbartonshire. This is one of the most infamous junctions in Scotland, and was formerly an at-grade roundabout. The junction had such a poor accident record that it was rebuilt ahead of the motorway upgrade of the A80.
