The B1440 is a T-shaped B-road in north Norfolk. The bar of the T was the original route of the A149 whilst the remainder was unclassified, gaining its number in the mid-1930s.
The road starts on the A148 just west of Hillington and heads north across the Sandringham Estate. To start with the road crosses fields and is merely lined with trees but it becomes more wooded as we continue. The B1439 is met at West Newton after which we pass very close to Sandringham House itself.
By one of the entrances to the grounds of the house an unclassified road bears off left and the B1440 continues along an avenue with expanses of grass on both sides separating the road from the wood. After a couple of hundred yards the avenue ends and the road zigzags left then right to leave the wood and enter Dersingham. We follow a lengthy route through the village to reach traffic lights at the original northern end of the B1440.
Following the opening of the present A149 bypass in 1990 the B1440 has been extended in both directions. The shorter route turns left and heads south, spending roughly equal distances in the village and in the wood before reaching a roundabout on the A149 (The Alderman George Pratt Roundabout). Meanwhile the road to the right remains largely built-up. After Dersingham it runs through Ingoldisthorpe and then Snettisham (there are brief rural sections separating the villages). After zigzagging through the streets of Snettisham the road ends at a roundabout back on the A149.
