The B5409 is a short link road to the south of Fleetwood. It was originally the northern end of the A587 but gained its number when that road was rerouted in the early 1930s.
The road starts at traffic lights on the A587 Broadway just by the Rossall School stop on the Blackpool Tramway. We head east along Rossall Lane, immediately crossing the tram lines, then continuing across flat land past houses on the left and fields on the right. It's not long before we reach a T-junction on the A585 Amounderness Way, where the B5409 ends. We are forced to turn left but all movements from the A-road are permitted.
Before the construction of the A585 bypass the B5409 continued ahead along the remainder of Rossall Lane to end on the pre-bypass road, now the B5268; this is no longer a through route. It is therefore unusual that the B5409 has kept its number.
