Hi Craig,
Unfortunately, we don’t have actual measurements we can provide you. However, there are various ways to obtain the best estimate: a) Use Google Earth’s measurement tools and b) Check this ADB’s report containing the classification of rural roads in Cambodia, where you’ll see road dimensions based on Annual Average Daily Traffic.
Lastly, check the drone overview of the Memang Primary School in our Interactives: 360° Site Walkthroughs, where you can zoom into the images of the connecting roads and read more information about transport ownership.
I hope this helps.
Regards,
Jean
