text: Thank you for your help, but the change you made is not correct: from tertiary road 251684299 you have to go to ring road R50. You cannot go to road 157558566. There is actually a fence which prevent you from going straight on. So there is no crossroad, but two 1-to-1 connections: tertiary road 251684299 with R50 and service road with road 157558566.
