|Route outline (key)|
The A1084 is a largely rural A-road in north Lincolnshire. Originally numbered B1209 the road gained its current number in the mid-1920s.
The road starts on the A18 (former A15) at the war memorial roundabout in Brigg. It heads south along Bigby Road and soon crosses the rarely used Retford to Grimsby railway line at a level crossing. Houses continue to line the road for some distance but presently open country is reached and the road meets the B1434 and then goes over the Lincoln to Grimsby line.
The route so far has been completely flat, albeit winding, but an ominous-looking ridge has been visible ahead for some distance. This is finally reached at Bigby, where the road zigzags up the steep hill before bearing right to run along the edge. To begin with the view is screened by the trees but it is soon possible to see for miles.
Remaining at the top of the ridge, the road passes above Searby then skirts the edge of Grasby. However, having made the effort to get to the top of the hill we now descend and by the next hamlet, Clixby, we're back at the bottom. We run to the west of the ridge for another mile or so to enter Caistor from the north before bearing left into the High Street. At the far end the road narrows and flow is controlled by traffic lights. Incidentally, this is the original southern end of the A1084, where it ended on the A46. When that road was moved onto the current bypass the A1084 was extended along Grimsby Road and we climb out of town, incidentally getting back to the top of the ridge again. After passing the Caistor Yarborough Academy the road ends at a T-junction on the A1173. The A46 bypass is a few feet to the right but the roads don't actually meet.
