Smart Motorway gantry sign
A gantry structure spanning the motorway with electronic signals, blue signs showing the left two lanes exiting and the other two continuing ahead, and the following text.
Left-hand two lanes destinations: M32 Ring road (A4174); Bristol (C) [Solid square diversion symbol] [Solid triangle diversion symbol] .
Right-hand two lanes destinations: London; Swindon, Bath M4 .
Junction number: 19.
The M32 will take you directly into the centre of Bristol, or if you want to spend the rest of your life driving around a succession of congested roundabouts, it will give you access to the A4174 ring road.
