OS MasterMap Highways

OS MasterMap® Highways Network is the most complete, detailed and accurate navigable road network dataset for Great Britain.

The detail rich product is the result of a £3m investment by The Department for Transport (DFT), made in 2014, for OS to develop road and transport information using data from authoritative sources and trusted partners.  One of the overall aims is to ensure traffic in Britain keeps moving efficiently and safely.
