|Route outline (key)|
The A129 is an old cross-country route, now part of the sprawling Essex network.
It begins its journey on the A1023 (the old A12 Roman road) a mile north east of Brentwood town centre. It heads east, passing Shenfield railway station, and on across a short section of open country to the southern edge of Billericay. At a roundabout here it is joined by the B1007 from the town centre and the A176 up from Basildon. By rights the A129 is the road ahead but this road is one-way towards us. Signage is unhelpful but presumably we turn right onto the A176, which also becomes one-way just before reaching the next roundabout where we turn left onto the northbound A176 to rejoin the A129 at the next roundabout, still on the edge of Billericay. Thus we travel for over a mile to cover a distance that westbound traffic (using the one-way A129) needs only a quarter of one.
From here the A129 continues east via Crays Hill to Wickford where a short section of dual carriageway leads to a roundabout on the A132 relief road. There is a short multiplex to the left. However, there is no gap in the central reservation to allow traffic to turn right onto the A129, so eastbound traffic must U-turn at the next roundabout to reach the LILO junction and regain the A129.
On reaching open country the A129 goes under the A130 before meeting the old line of that road, now the A1245, at a roundabout. The road enters Rayleigh and zigzags past the station to reach the High Street and a mini-roundabout. Here it turns right to meet the A1015 at the next mini-roundabout.
