M8 Glagsow - J17 northbound and J17/J18 westbound - Part I

The St George's Cross interchange is where the motorway turns through about 90 degrees at the NW corner of the Inner Ring Road.

The intersection allows access to the A82, the dual-carriageway leading out to NW Glasgow, and to local streets in the Charing Cross area.  The motorway, and parts of the junction, are in a short "cut and cover" tunnel.

The A804 comes in from the south with one carriageway on either side of the motorway, goes around the NW side of the motorway and finishes leading to the east underneath the elevated motorway.

The yellow lights for the matrix displays are flashing, but with no other sign shown - this is most unusual, but is standard on the M8 when there's congestion over several miles.  On quieter rural motorways, flashing yellow lights are used as a general warning of a hazard ahead, with a recommended speed of 30 mph, but a matrix would normally be showing the advisory speed limit.

I suspect that an advisory 30 limit is a bit pointless when the average traffic speed is 10-15.

The southbound auxilliary lane only joined at J18 and leaves again at J19, so the lack of traffic is only to be expected.

The bridge upon which it stands was built with the motorway in the early 1970s, but the office block was only added in the mid-1990s.

Note the unusual use of a green-backed sign on a motorway.

The two lanes of traffic under the camera are queuing to join the eastbound motorway.  This is the main access point for much of Glasgow's west end, and it's all funnelled into a single lane on the ramp - with queues stretching back miles at peak hours

Evening rush hour traffic isn't pretty...

 Looking south under the office building, the motorway can be seen climbing out to the south.
