Is there a Way to Display Toll Roads on Google Maps
Google Maps indicate that your route includes a toll road or partial toll road. However, it does not show toll roads as a layer or toll locations or toll amounts as markers.
To see toll roads on Google Maps, you need to turn on the 'avoid tolls' in the app.
Alternatively, use TollGuru Toll Calculator to see if your destination has toll roads en route. The calculator also shows all the toll plazas you'll cross and their details- toll rate, toll tag, discounts etc.
