in Northen Etchells township and partly in Styal parish. For many centuries it was a peat bog which was dug for peat fuel, locally called "turf"; local manorial law said that after digging peat the top living plant layer had to be lodged back to let more peat form afterwards. Each man's allocated part of the Moss was called his "moss room". In the 19th century, manorial control was lost over what people used their moss rooms for, and an 1839 tithe map of Northen Etchells shows Northen Etchells's part of Shadow Moss as about 2/3 arable, about 1/3 meadow, one field as pasture, and one field as "uncultivated moors". Later, the fertile lowland peat soil led to the area being much used for market gardening, with large areas under greenhouses. Of the people who worked there, many lived in Heyhead. As of around 1970, Heyhead was a small settlement at the south end of Woodhouse Lane and the nearby part of Ringway Road. It comprised several terrace houses, a small shop, two or more old cottages, a chapel, and the Ringway Haulage Company. Manchester Airport's ground level car parking has been displaced from other areas and car parks have been formed to the north and south of the runways and under the approach path. The Heyhead area has been progressively replaced by level car parks, and by 2011 all of Heyhead's buildings had vanished (see History of Manchester Airport#Expansion). Some greenhouses remain at the far east of the Shadow Moss area as of June 2012, but are used by private car parking operators (not associated with the airport company) and not for growing any crop. The last market gardener there, who grew tomatoes, closed his business in 2011 due to competition from highly mechanized enormous greenhouse establishments elsewhere. Public services Wythenshawe is policed by the city of Manchester Division of Greater Manchester Police. Wythenshawe's fire and rescue services are the responsibility of the Greater Manchester Fire and Rescue Service, and are based at a fire station on Brownley Road. Transport The M56 motorway, constructed in the 1970s as a continuation of the A5103 road (Princess Parkway), bisects east and west Wythenshawe. A bypass connecting it to the nearby M60 motorway was built through Sharston and opened in 1974. The nearest railway station to Wythenshawe was located adjacent to Longley Lane at the edge of Sharston on the Cheshire Lines
