South of the Sadlers Farm roundabout, the final leg of the A130 continues as a non-primary single-carriageway route into Canvey Island on the River Thames. "Canvey Way" is a causeway connecting "mainland" with island, and connects with the older road through the island, the B1014. On the island itself, a final short stretch of dual carriageway leads to the built-up area where the road turns east and becomes single, before meeting the B1014 again at a one-way system in the central area, incorporating the "High Street".
