I am working on a mobile navigation app that aims to present a simplified turn by turn navigation on screen. I want to show the calculated route and as a line on screen and then show all roads that are connected to my route so that there is more context for user.

Essentially I want to achieve something like on this screen (bold line is my route and thin lines are connected roads):

Is there a way to get this connected road information from Google Navigation SDK or some other SDK, eg mapbox?

I’ve spent a lot of time researching it but failed to find any ifo on how to achieve this result
