The A1110 is a short link road in north London.
The road starts at a roundabout where it meets the A109 and A1003. It heads east along Bowes Road, crossing the Piccadilly Line by the striking Arnos Grove station about half way along. The road ends at a signalised crossroads on the A406 North Circular. That road TOTSOs here.
In 1922 this part of Middlesex was fairly rural and whereas the A109 and A1003 existed, what is now the A1110 appeared to be a country lane. The road is marked as under upgrade to Class I status on the London MoT map; this road continued as new-build east to meet the A111 near Edmonton. It is likely that this entire road was opened with the A406 number. A few years later, however, that road was diverted onto another section of new-build to the south of New Southgate and the section vacated became the A1110.
