M8 Glasgow - J19/J18 Anderston - Part I

Southbound, J19 is where local roads from three directions, plus through traffic on the M8, all funnel onto the Kingston Bridge across the Clyde.

Northbound, this junction includes exits for both J19, leading to the Clydeside Expressway,  and J18 for Anderston/Charing X and for the City Centre.  However, the northbound motorway on the bridge is partitioned, with the two lanes which joined at J20 leaving at J19 and J18, and traffic from the mainline only able to exit towards the City Centre from J18.

The A814 Argyle Street crosses E-W underneath the junction, leading west to the Clyde Expressway.  The A804 runs parallel with the motorway, directly underneath to the south of the junction and on either side to the north.

These gantry signs are all backlit, hence the very deep box section and rigid construction. 

The signs themselves consist of an upper information panel with directions and a lower panel with a small matrix display for each lane.  Each matrix is bracketed by pairs of amber and red lights which flash when the lane is restricted or closed.  Where a lane splits, it gets two matrix panels close together, one for each direction.

While most of the direction signs are standard motorway white-on-blue, the panels above lanes which exit immediately are usually black-on-white.

In this case, two lanes exit - for two different destinations - and two lanes continue on the motorway.  The junction number, 18, is shown in a separate black panel at the top left corner of the gantry.

The M8 is running in the middle, with the gantry sign.  The ramps above and below are from and to the A814 Clyde Expressway

The A814 Argyle Street passes underneath the M8, with the A804 crossing on the level beneath the motorway. 

The ramp descending from left to right is from the eastbound A814 to the southbound M8, with the opposite flow descending from the motorway on the far right.

This is a proper mainline railway station, with both local and long-distance services. 

(Glasgow's Underground is completely hidden from view in deep-level tunnels.)

This end of the bridge has no guardrails at all, and the base of the spiral is protected by a high spiked fence. 

The other end does have guardrails, but finishes abruptly with a 60 foot drop.
