At its western end it meets the A13 and the A176 at Five Bells, and then heads east along London Road, showing the road's history. At a mini-roundabout it meets the B1419 Clay Hill Road north to Barstable; this has been marked on some maps (e.g. OS, Google, Bing) recently as a spur of the B1464, although in the most recent A-Z of Essex, the road is given the B1419 number, so something's wrong somewhere!
East of Clay Hill, the road is Pitsea High Road. It passes under the London, Tilbury & Southend Railway and the A132 before becoming Pitsea Broadway. A short spur of no more than 200 yards links Pitsea Broadway with the roundabout under the A13 Pitsea Flyover which also provides access to the A132.
Continuing east, the road is London Road once more. There's a mini-roundabout with Rectory Road and a second one with Church Road, which crosses the A13 a very short distance to the south, after which we reach a light-controlled junction with Pound Lane. On the edge of town we get to the former magic roundabout at Sadlers Farm, where the B1464 ends and the A13 continues on its original alignment east of there towards Tarpots, Hadleigh and on to Southend and beyond. The north-south road is the A130.
