B5300 road The B5300 (known locally as the Coast Road) is a B road which runs for approximately twelve miles between the towns of Silloth and Maryport in the Allerdale borough of Cumbria, United Kingdom. From north to south, it passes through the villages of Blitterlees, Beckfoot, Mawbray, Dubmill, and Allonby. It runs through the Solway Coast Area of Outstanding Natural Beauty, passes close to the Salta Moss Site of Special Scientific Interest, Milefortlet 21, a Roman archaeological site, the salt pans, a remnant of the Solway plain's medieval saltmaking industry, and the village of Crosscanonby. It is an important route for carrying goods to and from Silloth docks and Maryport harbour. It is also the major road connecting smaller coastal settlements with Maryport and Silloth, from where other roads lead to Workington, Whitehaven, Wigton, and Carlisle. A short section of the road between Dubmill and Mawbray was closed in February 2019 due to coastal erosion, and reopened in June 2019. The route Silloth-on-Solway to Beckfoot The B5300's northern terminus is close to the town centre of Silloth-on-Solway. The cobblestone B5302 gives way to the paved B5300, which then crosses over the old railway bridge that once led to Silloth railway station before winding past the Crofts estate and Stanwix holiday park on its way out of Silloth. The short stretch of road after departing Silloth is the furthest away from the shoreline that the B5300 gets during its entire twelve miles, and after passing through the village of Blitterlees just outside Silloth, and coming within a hundred yards of the hamlet of Wolsty, it joins the coast. The next settlement on the route is the hamlet of Beckfoot, about a mile and three-quarters from Blitterlees, and upon entering, the B5300 passes from the parish of Holme Low, where it has been since departing Silloth, into the parish of Holme St. Cuthbert. Bank Mill to Dubmill A mile south of Beckfoot is the side-road which leads to Newtown, and also to the Gincase, a farm park and tearoom. Immediately past the Newtown road comes Bank Mill Nurseries, which includes a garden, nature reserve, play area, and restaurant. The B5300 continues past Bank Mill, with sand dunes known locally as Mawbray Bank on the shore side, and agricultural land belonging to local farmers on the land side. The road then arrives at the western end of the village of Mawbray, and passes by a farm and several houses. There are two turnings here, one which leads away from the shore and into the village itself, and another unpaved road which leads to Mawbray Yard, a small collection of homes located very close to the beach. Near Mawbray Yard there is also a car park for visitors to the Solway coast Area of Outstanding Natural Beauty, which incorporates much of the road's route. Shortly after passing Mawbray, the B5300 takes a more southerly turn at Dubmill Point. This marks the start of Allonby Bay, an inlet of the Solway Firth. There are two side roads within a couple of hundred yards of each other in the vicinity of Dubmill, the first leads to Salta, and ultimately on to Mawbray via Hailforth, and the second leads to Edderside. Also along this section of the road, a large concrete sea wall is present to prevent erosion and damage to the road or nearby farms. However, particularly heavy storms have damaged the sea defences in the past, and in 2014, Cumbria County Council launched a £130,000 repair scheme. In the first half of 2015 major repair work has been carried out to the sea wall
