> In its own day, the Arc crossed only one international border, between Sweden-Norway and the Russian Empire.

Looking at the map, it's not really clear why they decided to veer west to Swedish(-Norwegian) side of border instead of sticking closer to the Tartu meridian and staying within Russian(-Finnish) borders, terminating somewhere near current-day Utsjoki. Does anyone know the rationale for the route?
