Editing Ermine Street (section)

==Alternative courses==

The author Thomas Codrington proposed a more westerly route for "Erming" Street north of London, going via what is now [[Theobalds Park]].<ref>{{cite book |first=Thomas |last=Codrington |url=https://penelope.uchicago.edu/Thayer/E/Gazetteer/Periods/Roman/Topics/Engineering/roads/Britain/_Texts/CODROM/4*.html |title=Roman Roads in Britain |publisher=Society for Promoting Christian Knowledge |location=London |date=1903}}</ref> This route is marked on many maps.

The [[Roman roads in Britain|Roman Map of Britain]] above shows a sector of Ermine Street for which there was an alternative route. As Ermine Street extended north out of Lincoln and past [[Scampton]] an alternative course of Ermine Street curved left and formed a semicircle on a wide heading west of the [[Humber Estuary]]. The straight northerly route, traced in red on the map, between [[Lincoln, Lincolnshire|Lincoln]] and [[York]] was the shorter, but was not passable over the Humber Estuary during adverse weather conditions. Thus an alternative route was established (see also [[Roman roads in Britain]]). This 'alternative' route is detailed in the [[Antonine Itinerary]] and linked York (Eboracum), [[Castleford]] (Lagecium), [[Doncaster]] (Danum), [[Littleborough, Nottinghamshire|Littleborough]] (Agelocum) and Lincoln (Lindum). Beginning at the modern Lincolnshire Showground the portion of this route in Lincolnshire is known as [[A1500 road|Till Bridge Lane]], the modern A1500.<ref name=OS121>{{cite map |publisher=Ordnance survey of Great Britain |title=Lincoln & Newark-on-Trent |date=2 June 2011  |scale=1:50 000  |series=OS Landranger  |section=121 |edition=C3 |isbn=9780319229422}}</ref> The route in the Doncaster area, and again north of Castleford, is known as the [[Roman Ridge, South Yorkshire|Roman Ridge]] or [[Roman Ridge, South Yorkshire|Roman Rigg]].

A large section of this road formed for many later centuries the [[Great North Road (United Kingdom)|Great North Road]] between [[Nottinghamshire]] and [[West Yorkshire]].
