Most of Hällstigen is renamed Timvinkelvägen.

Timvinkelvägen is also extended roughly between coordinates 59.18493,18.14317 and 59.18466,18.14120

The part that splits off south-east from coordinates 59.18493,18.14317 is still called Hällstigen.

The more exact stretch of the road extension can be found in Haninge Municipality's public plan of the area here: http://haninge.se/globalassets/bygga-bo-och-miljo/oversiktsplanering-och-detaljplaner/detaljplaner/vega-hermanstorp/stadsdel-vega-2/plankarta-lk.pdf  (south-easternmost part of the highlighted plan area)
