Hi TfL, I would like the GIS layer for the Transport for London Road Network (TLRN). Unfortunately the TfL website link doesn’t work – it seems to take us to a hefty amount of acc stats data. https://tfl.gov.uk/info-for/open-data-users/our-open-data#on-this-page-9 Geographic boundary of the GLA road network This data set includes the geographic boundary of the Greater London Authority road network for which Transport for London is the Highway Authority. Sections 14C of the 1980 Highways Act requires TfL to maintain a record of the roads for which it is the Highway Authority. The dataset(s) published here are TfL's record in map form. The boundaries are for visualisations at scale of 1:1250.
