|Route outline (key)|
The A6121 is a medium-length A-road centred on the Lincolnshire town of Stamford.
The road starts on the A47 in the Rutland village of Morcott. It heads northeast along Stamford Road, entering open country almost immediately. The next village, South Luffenham, is reached after about a mile, then the road meets the Leicester to Peterborough railway line and runs alongside. The road is above the railway line for a short distance, then the road drops down and bends sharply left to cross the River Chater and then go under the railway line.
On the far side of the low bridge the road bends right and heads east once more, following the railway line albeit not too closely. We soon reach the village of Ketton and run along the High Street, then pass a cement quarry on the way out of the village. After going through the small village of Tinwell we cross the A1 at a GSJ and enter Stamford.
The road enters town along Tinwell Road then bears left at a mini-roundabout onto West Street, to bypass the town centre. The A606 is met at traffic lights then we run along East Street, with the town centre to the right, and shortly reach another set of lights. The road ahead is the A1175 and we turn left and multiplex with that for a short distance past Stamford School to a mini-roundabout where the two roads go their separate ways.
The A6121 bears left and heads north along Ryhall Road, soon entering open country once more. We skirt the western edge of the village of Ryhall and then cross the River Gwash. On meeting the B1176 we bear right to run alongside the river for a short distance before regaining our northerly course. The East Coast Main Line is crossed at Essendine, although there is no station. The road winds on for a few more miles, passing through Toft, and presently reaches a T-junction on the A151 to the west of Bourne. The A6121 ends here.
The road from Morcott to Stamford was built in the 1750s, as a turnpike road (which extended to Market Deeping along the present A1175). On classification in 1922 it became the B672, then the A6121 in the mid-1930s.
The route from Stamford to Bourne was originally the B1174 until around 1968, when it was merged with the section south of Stamford to give the A6121 its current length.
