 The Elton Bypass takes the A605 onto a new more southerly route to join the A1(M) at its northern terminus at Junction 17.This route then overlaps the A1 for to Alwalton where it regains its original route, heading northeast through Orton towards Peterborough.The bypassed section from Elton to Orton suffered from poor alignment and is now the B671 and a C road.
