I am not entirely sure if I did this right or not and would definitely like a second opinion.
Busway
Although it does not look like much now, you can see the construction on satellite that shows the bus path continuing north and replacing the abandoned Grand Junction Branch railway. Since this particular portion has been there for what may be more than a decade now (surprised it wasn’t in the system in the first place), I decided to use this to test out the appropriate setting before continuing with the rest of the route. Decided to use the Service Road since that is what the roadways at Wood Island Station uses.
