Imperial High Road
From Dragon Eye Atlas
The High Road connects many of the major cities of the realm and reaches from Aphideret in the south to Gonos in the north-east. A second part of the High Road connects Bukunga to Tritigesus, but is not yet linked to the main segment.
The map on this page shows the full extent of the High Road, visible as the widest road on the map (depending on your resolution, you may have to zoom in for the road to become visible).
By imperial edict, the High Road is to be made as a paved road with a stone slab surface throughout. In fact, much of it does conform to that requirement, though quality and width of the road differ. It nevertheless is the best road available in almost all the places it passes through.
In its best parts, the High Road is built with stone bridges, a slightly curved top so the rain runs to the sides, and a solid gravel fundament on which stone slates are placed to create a sturdy and reasonably flat road surface. In other places it is little more than an existing road with stone tiles layered on top.
Aside from the road itself, the founding papers of the High Road project also include rules for safety and comfort.
The Road Wardens were founded as part of the project to ensure the safety of the High Road as well as patrolling for obstacles, damage and other problems.
A network of roadside inns was also set up, with incentives for prospective innkeepers. There is a roadside inn every at most 30 km along the High Road, except where a town or city is so close as to make it superfluous. This distance can be comfortably covered by travellers on foot or with pack animals as well as with horses and waggons thanks to the quality of the High Road. Travellers on foot with heavy luggage do find those distances challenging sometimes, and typically start their trips very early to ensure they will reach the next inn before nightfall.
Every such roadsinn inn also has a signpost outside indicating the distance of the next inn and the next town or city in each direction.
