|Route outline (key)|
The A1112 is an urban A-road in south Essex.
Its northern end, however, is quite rural. It starts at a roundabout on the A113 to the west of Abridge and heads southeastwards across the fields. A few houses are passed and eventually a 30mph sign is reached and the road enters Chigwell Row. It becomes dual-carriageway at a signalised crossroads where it meets the B173, after which it skirts Hainault Forest Country Park and enters the London Borough of Redbridge.
The dual carriageway continues uphill back into open country, although a golf course is also passed on this section. The road then becomes urban once more as it reaches Marks Gate. The A12 is then crossed at traffic lights, after which the open spaces are left behind completely. The A1112 continues south through Chadwell Heath and gains a central reservation again as it crosses the bridge over the Great Eastern Main Line. About half a mile further on a set of traffic lights is reached opposite the bizarre Becontree Heath Leisure Centre.
There is a short multiplex east along the A124 (which itself TOTSOs at this junction) to the next roundabout, adjacent to the civic centre. The A1112 regains its number by forking right to run along the D2 Rainham Road North, which narrows again soon before it becomes Rainham Road South. The District Line is then crossed adjacent to Dagenham East station, after which the A1112 forks left at a roundabout. It becomes D2 again here and runs vaguely eastwards for over half a mile. It crosses the Beam River to reach another roundabout where it ends on the A125.
The A1112 did not exist on classification in 1922.
Originally, the road from Abridge through Chigwell Row was numbered B174, the remainder of which still exists to the east of the golf course. The road through Marks Gate was unclassified and the road from Becontree Heath through Dagenham to the A125 was the B178.
The A1112 was inaugurated in the late 1920s. Its original route started on the A106 (present A12) to the north of Chadwell Heath. It ran south through Becontree Heath to end on the A13 (now A1306) to the north of Dagenham Dock. It retained this route until the 1970s when the northern end was extended and the southern end rerouted.
To the north, the A1112 was extended along what had become the B196 and then the B174 to reach Abridge. To the south, the A1112 south of Becontree Heath was renumbered A1240 and the A1112 rerouted along the B178. This gave the road its current form.
