In the A Song of Ice and Fire novels, the exact geography of the region around the Inn at the Crossroads and nearby fords of the Trident River has been the subject of a little confusion: some sources say that the River Road joins with the Kingsroad before it crosses the Trident River (and thus, the Ruby Ford is the only river crossing), while others say that the River Road joins with the Kingsroad after they both separately cross the Trident (in which case, the River Road has its own separate ford west of the Ruby Ford). Loosely speaking the Eastern Road is the eastern continuation of the River Road, but they are considered to be separate thoroughfares, apparently due to the major differences in topography between them (wide and wet river paths versus treacherous and narrow mountain paths). The Inn at the Crossroads is located near this junction.

Just north of the river crossings, the River Road joins with the Kingsroad and the High Road at the crossroads. Slightly east and downriver from the crossing of the River Road is the crossing made by the Kingsroad, known as the Ruby Ford.

In the east of the continent, just east of the point where the three forks of the Trident (Red, Blue, and Green) merge, the River Road crosses over to the north bank of the combined Trident River. The River Road runs northeast from Lannisport to Riverrun, but after passing Riverrun the Red Fork and the road curve to follow a more even east-west route. From there, the River Road predominantly runs alongside the south bank of river across the width of the Riverlands (hence the road's name), through the heart of Westeros. At Riverrun, the road crosses over the Red Fork of the Trident River to its southern bank. The road leads roughly northeast from Lannisport until it reaches Riverrun, the capital of the Riverlands. The River Road exits the Westerlands through the only major pass in the mountains along their northeast border with the Riverlands, a pass watched over by the strategically vital fortress of Golden Tooth. It runs west to east across the continent from Casterly Rock and Lannisport on the west coast, to the crossroads with the Kingsroad and the Eastern Road near the Inn at the Crossroads. The River Road is a major highway in the Seven Kingdoms. A map of the Riverlands, with the "River Road" clearly marked.
