The A1108 is a short urban A-road in southeast Northumberland. Originally numbered as part of the B1316 it presumably gained its current number following the construction of the A1058 in the late 1920s.
The road starts at a roundabout on the A193 Front Street in Chirton and heads north along Billy Mill Avenue. This is a residential road lined with trees. The road climbs with the occasional bend and changes its name to Regent Terrace (despite being lined with semis). A roundabout is crossed after which the A1108 ends at the next roundabout, where it meets the A1058 and B1316.
