You Can do this but you need to convert your instructions into geographic coordinates. For example purposes, let’s assume you have these coordinates (you would normally obtain these by geocoding your milepost or known points)

Start - Iowa border at US-61 (e.g., LatLng(42.0, -91.0))

North Point - 16.3 miles north (e.g., LatLng(42.15, -91.0))

Turn Point - Intersection with WI-133 (e.g., LatLng(42.15, -91.02))

End of Outbound - Potosi (e.g., LatLng(42.16, -91.02))

Return Trip - You can reverse these coordinates or define them as needed.

Insted of the instructions you need to send pints from where to where the google map build the map for you according to those points is this help

I used below code to parse instructions and get LatLng based on instructions. After getting LatLng I will set a marker point on that LatLng and draw a polyline between all instructions. But I will not draw path for road it will draw direct staright line between points PLease check this doc : docs.google.com/document/d/…
