The County or 'C' Stones of Dartmoor are often overlooked as a feature of Dartmoor roads. They are always found near the major bridges of the moor and originally would have consisted of a pair of stone pillars incised with the letter 'C' which denoted the word 'County'. Today many of them are either missing, have become lost in thick undergrowth, or are unrecognisable due to thick coats of mosses and lichens.

After the dissolution of the monasteries, Henry VIII realised that subsequently he had lost a major source of funding and administration for the road systems. In order to make up for this shortfall he introduced a 'Statute of Bridges' in 1531 which laid down a basis of bridge administration. It was so effective that the statute remained in place until the County Councils were established in 1880.

The aim of the act was to make sure that bridges should not fall into disrepair purely because nobody was accountable for their maintenance thus causing them to, "lie long without amendment to the great annoyance of the King's subjects." The actual machinery of the statute stated that the bridges were maintained by the various counties, i.e. Devonshire, which came under jurisdiction of the magistrates of the Quarter Sessions. It was stated that: unless it could be proven that: "a Hundred, Riding, Wapentake, City, Borough, Town or Parish or what person certain, or Body Politic" should by right maintain a bridge then a shire or county was obliged to do so.

 In order that the act was funded and complied with each county levied a rate on all the inhabitants of the administrative area. Each county would appoint two collectors to gather the rates and two surveyors to oversee that any bridge repairs were carried out. It is said that this levy was the foundation of the present rating system. In Devonshire things are always looked upon differently and so initially there were just two collectors appointed as it was decided they could do without the surveyors, well until 1703, anyway.

The act required that for every bridge the road over it and for 300ft on either approach should be similarly maintained. In 1841 the Devon magistrates decided that the limits of their responsibility were to be marked by boundstones. These usually were about 3 feet high with an incised 'C' on one of the faces and placed one on either side of the bridge, it is said that at the time each stone cost 7/6d each to erect. Below is a list of the Dartmoor bridges where one or more of the stones are still in-situ:
