In Sword Coast Adventurer’s Guide, Mike Schley’s map shows a series of gaps in the Trade Way/Coast Way between Waterdeep, Baldur’s Gate, Sconubel, and points east. The version available for free on the Wizards of the Coast website shows the gap:
I figured the interrupted road between Scornubel and Dragonspear Castle at least was a misprint, but subsequent versions of the same map show the same discontinuity. The version currently for sale on Mike Schley’s website has been updated for Storm King’s Thunder, with all of the roads redrawn. However, the gap persists.
Descent into Avernus implies that there is a road continuing north from Baldur’s Gate, though it could be interpreted to refer to the stretch of the Trade Way that resumes farther north.
With trade ways running north and south along the Sword Coast, a port on the Sea of Swords, and the Chionthar River leading inland, Baldur’s Gate is perfectly situated for its role as a commercial hub.
The map showing the immediate environs of Baldur’s Gate remains consistent with previous editions, although in this the road makes it as far north as Boareskyr Bridge before terminating.
Is there a canonical reason for this? Does all trade between Baldur’s Gate and Waterdeep take place by water? Or is this still a misprint? The Forgotten Realms Wikia shows no such interruption, but it tends to have a heavier focus on earlier editions.
