|Route outline (key)|
The road starts on the A1175 southern bypass and heads north. It crosses the South Drove Drain immediately and then runs into the suburb of Little London. There's a short stretch alongside the Spalding to Peterborough railway line after which the road bears right and reaches a bridge over the River Welland. On the far side is a T-junction on the B1173 but in fact the B1172 TOTSOs left immediately before the bridge.
The B1172 runs downstream alongside the River Welland, with the B1173 on the other bank. There are occasional bridges between the two, the first being an old railway bridge that still exists even though the line has now been removed (pedestrians can use a footbridge that runs alongside). As we reach the town centre there's another road bridge, accessed via traffic lights, and the B1172 becomes one-way in this direction on the far side.
After following the river for a bit further it is separated from us by houses on the right of the road. The road then unexpectedly becomes two-way (presumably for local access - but traffic coming the other way would find it almost impossible to turn round). Shortly afterwards the road bends sharply left as we head back into the town centre. The road TOTSOs right at traffic lights and ends shortly afterwards at a signalised TOTSO on the A151.
