A gantry spanning the motorway with blue overhead signs indicating two lanes exiting and two continuing ahead, and the following text.
Left-hand two lanes destinations: A4 [Hollow circle diversion symbol] Bristol & Airport [Airport symbol]; Shirehampton .
Right-hand two lanes destinations: Avonmouth & Docks; Aust (A403) A4 .
Change Route: A4 Bristol
The Avonmouth Spur branches into two smaller Avonmouth Spurs, both leading to a roundabout on the A4. Ahead lies Avonmouth itself, or exiting here will allow you to head for Bristol. Though - truth be told - you can get to any of these places from either spur.
