Wennington Interchange is a junction on the Greater London/Thurrock boundary. It connects the 1990s A13 to its former (post-20s) route, which is now the A1306.
1960s plan for a junction with the A13 running north-south
Online dualling of the A13 was planned in the 1960s and the junction would have been sited slightly to the north where it meets the B1335. Had that junction been built it would also have served two generations of the A13 with the B1335 being the original route.
Instead the A13 was diverted onto a completely new alignment further south in the 1990s. The section west of Wennington opening in 1997 and the section between Wennington and the M25 opening in 1998.
