The A5105 is a coastal road in north Lancashire. It was built in the 1930s and has presumably held the A5105 number since its opening.
The road starts at a TOTSO on the A589 Marine Road East to the east of Morecambe town centre. The road heads east, keeping the same street name, and soon becomes dual. Lanes are not marked but there is more than enough room for through traffic to pass parked cars. There are a few gaps in the central reservation to allow access to side streets, one of which is the B5275, after which the road narrows.
Hest Bank
Continuing along the coast we soon reach the edge of town. We pass a golf course and turn inland to cross the West Coast Main Line and enter Hest Bank. The road runs alongside the railway line for a short distance (although it's hardly visible as we're lined with buildings) before we bear right. We now skirt the northern edge of the settlement - the right of the road remains built-up but there are only a few buildings on the left so open fields are often visible. This merges seamlessly into Bolton-le-Sands (so called to distinguish it from Bolton-le-Moors) and we end at set of traffic lights on the A6 to the south of the village centre.
