The A151: summary

In the early 19th century, the A151 would have been called a cross-road since it runs across the pattern of these radial routes. As originally designated, it ran from the A15 at Bourne Market Place (), eastwards to Fleet Hargate, three kilometres east of Holbeach (), on the A17. Its present western section, between

History: turnpike roads

As elsewhere, roads in England have developed over many years. Perhaps some of the A151 lies on lines which are pre-Roman. In other words, parts are two thousand or more years old. However, change is constant and little of the road is that old. In the nature of things, these changes are poorly or not at all documented, so will be treated generally, in that light, in an overview below. The historical part of the story begins with the turnpike roads. The A151 was originally designated such in 1921. Then, the roads were much as they had been forty or fifty years before, under the turnpike trusts. Since the
Second World War World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the wo ...
, there has been much building of by-passes and the like so that the precise lines have sometimes changed but they are still fundamentally the same. The main difference in the present case is that the road designation has been extended from the A15 at Bourne to the A1 at Colsterworth, while at the other end, the easternmost three kilometres have been replaced by a new part of the A17. In the field of acts of Parliament founding turnpike trusts, much was happening locally in 1756. The Wansford to Stamford trust on the Great North Road had been set up in 1749 but in 1756, its sphere was extended through Stamford to Bourne. The last 1.6 kilometres of this road, as the trust left it, running down the hill to Bourne Market Place, are now part of the A151. It was freed from tolls on 1 November 1871. The half of this section which lies outside the modern town was probably built by the trust between 1756 and the Bourne

Trust was also established in 1756. Its remit included the forerunner of the present A15 which crosses the end of the Stamford road at Bourne Market Place. However, also included with this was the road from the Stamford road west of Bourne (a place known locally as Stamford Hill), to Colsterworth. With the exception of the western extremity, in Colsterworth village, this is now part of the A151. It was freed from tolls on 1 November 1882. The Lincoln Heath to Peterborough trust was organized in districts of which that covering the road from Colsterworth to Stamford Hill, Bourne was the ‘'West District'’. In 1860, it was re-grouped with the ‘'Middle District'’ which extended from Graby Bar () to

The Ordnance Survey does not note the Friars Bar toll gate but in the Exeter Estate book, the position is called Friers Bar though no obstruction of the road by a gate is indicated. '' Paterson's Roads'' is a road book listing the features of roads and mileages from the ends of its itineraries, sequentially. It is noticeable and a little surprising that according to the Ordnance Survey, it was possible in some cases to go a long way out of a town before coming to a toll gate. This is particularly noticeable eastwards from Spalding.


Condition of the turnpike roads

We have a few references to the condition of parts of the turnpike forerunners of the A151.

He therefore, will have taken the future A151 between Spalding and Fleet Hargate on his journey from

in general, and they must be esteemed below par.'' What he is saying is that the turnpike roads in the Townlands were made of the same marine silt as forms the land itself in that part of the country. The heaviness in dry weather to which he refers, arose from the loose, deep, sandy surface through which wheels would have to be dragged. According to Wheeler, of silt was reckoned to cover in a length of a road, thick and wide, the silt costing about 8d. to 10d. per ton for digging and spreading. In some cases the road was turned over. That is a pit was dug in the road until the silt was reached then that was dug out and formed into the carriageway. The surface of the next length was dug and put into the pit as a foundation then the silt dug and placed on top of it and so on along the road. Gravel was used where obtainable and from about 1870, Wheeler introduced

When roads are built by engineers with capital to support their work, they are successfully able to build roads across difficult soils. Modern road builders have less need to seek out easy geological conditions. When roads were made not by civil engineers but by people walking on the ground, the road followed the

from the year 43. An important part of the means of control was the building of soundly-built roads, running directly between key places. This led the engineers to overcome all but the greatest obstacles rather than going round them. One result of this was that they built roads on soils which others would have avoided. When the Roman authorities had withdrawn from Britain and their roads wore out, people began to wander from the

below it. Thus, in 1756 when the Colsterworth to Bourne road was turnpiked, the toll road which was to become the A151 began at the crossroads in Colsterworth, further west than it now does, though the first toll gate noted by the 1824 Ordnance Survey map was about three kilometres from there. When the Colsterworth bypass was built, its southern half was placed virtually on the Ermine Street line so that now, while the A151 still begins at the A1, it is not at the old Great North Road but at Ermine Street, on the chalky till soil that we start our journey.

Corby Glen

At the end of the wood, we leave Colsterworth parish. Three kilometres from the start, at the hamlet of Birkholme, the road finds a shallow valley formed by erosion which has cut through the till and exposed the underlying Jurassic limestone soils. Here, the 1824 map shows our first toll gate, Corby Toll Bar. The road follows this valley, under the railway main line, past the second toll gate site at the junction with the Boothby Pagnel road (B1176), then down to the River Glen at

Through Grimsthorpe and Edenham, there are numerous bends and winds across the small exposures Jurassic soils, glacial gravel and alluvium, until the road climbs out of the valley over the till-capped ridge which separates Edenham parish from Bourne. On the glacial clay soil of the till, it passes between woods, including Bourne Wood.

, on the other side of the A1, hence its beginning with the digit 6. In 1824, there was a toll gate here. The course of the A151 is directly down the slope into Bourne. It is clear archaeologically that the road used to run parallel with this and about 200 metres to the south. Historically, there appears to be no commonly available record as to when the move was made. It was certainly in two stages. The move of the upper part was probably made in the 18th century; the lower, in about 1140, when Bourne castle was built across it. Its present course is dictated by the former presence of Bourne Castle at the town end and by a desire to keep to the crest of a slight ridge in the hillside. It is towards the top of this section that it is possible to detect a change in slope betraying the former presence of a shore of the Devensian

lake, which was impounded by the ice into the Fenland basin. It was more evident but the declivity of the road has been smoothed out a little. Much more modern, is the bypass road which joins from the south at the entrance to the town and just below the level of the surface of the former lake. This opened for use on 8 October 2005. In the town, the A151 passes immediately outside the castle site, along the latter's northern edge. However the plots along this side of the road were first laid out for houses in around 1280, so that the castle is no longer casually apparent. At Bourne Market Place, the A151 crosses the A15. This road used to be part of the Lincoln Heath to Peterborough turnpike road, whose act of parliament is dated 1756. It was this trust which, in 1820, demolished the old town hall which used to stand in the street here. At the junction, the road to the north led directly form the main gate of the castle. The market place was positioned immediately across a moat and a pomœrium, outside the gate but those are no longer visible from the road. However, our road continues not straight ahead but on a 45° angle toward the south. This bend arose because it passed around the perimeter of the pomœrium until it met the road leading eastwards from the gate. As the A151 reaches this, it turns back through 45° and continues eastwards along that approach road, across the line of the Roman version of the A15, King Street and past the Abbey Lawn. This is now a picturesque

, 3 to 3½ thousand years ago. This was before the peat in the soil was laid down. In the black fens, the buildings are virtually always to be found on these old creeks, known as roddons. The many small roddons in Bourne North Fen merge at Twenty. There, the road uses part of this larger roddon by turning along it towards Guthram. Nowadays, this place is called Guthram Gowt but until the steam drainage engine was erected there, in 184?, it was Guthram Cote. In the late medieval period, people lived on the fen edge and the Townlands but the fens themselves were thinly populated. There were however, a few comparatively grand establishments called Halls, Neslam Hall at , for example. It was a grange of Sempringham Priory on the site of the modern Mornington House round which the district boundary is still diverted as it was when the abbey, on the Kesteven fen edge, owned it. There were more but still rather few smaller dwellings called cotes. Moors Cote lay in Bourne North Fen, to the south-east of Twenty and Guthram Cote stood on the boundary between Kesteven and Holland, on an island of Devensian deposits, the Abbey sand and gravel. The road book, Paterson's Roads, of 1826, lists a toll gate at Guthram Cote, a distance of from Bourne. Just to the east of this was the bridge over what it calls the South Forty-Foot Eau(15).

The present layout of the drainage dates from the act of Parliament of 1765 but this part of the South Forty-foot is a re-use of one of the main drains of the Lindsey Level, a scheme which was declared complete in 1638. On the other side, in Pinchbeck North Fen, the road begins to wind, something quite unusual in these fens. It was laid out on the bank of a

called the Weir Dike, which was cut in about 1600. In Pinchbeck North Fen, the dike is now largely defunct. The instructions stipulated that it should be at a distance of 100 feet (33M) from the bank of the River Glen. As the river bank meandered a little, so the road does(13). The river is the one the A151 crosses at Corby Glen and Edenham. Here the two parts are combined. Beyond the Glen, to the south, is an area of dense

occupation. On this side, a little is known but if there is more, it is covered with post-Roman marine silt(14). It looks as though this part of the river began as a single sea bank, keeping the tide out of Pinchbeck South Fen but allowing it into the lower part of that area behind the townland to the north of the road. In the late Roman or early post-Roman period, the Glen escaped from its artificial Roman course of which the Bourne Old Ea was part. (The road follows the bank of this while leaving Bourne) and found its way to these tidal flats. Later, at some early but unknown medieval date, the marsh was turned into a polder of sorts and the Glen was directed along the old sea bank which then became one of the river banks. Thus, the course of the road was determined ultimately, by that of the sea bank. The River Glen will have been in the phase when it flowed into the tidal marsh, with its mouth at Guthram, at around 500, the time when the unknown writer who goes under the name of
