[1] The Romans also constructed a wooden bridge crossing over to the right side of the Hinterrhein, routing traffic via Reischen to Zillis.

The Count of Werdenberg's 1473 letter required the cooperatives to design the new path for significant loads, including horses and a "chariot or sled", evincing a high level of technical sophistication.

In the northern part of the gorge this new path did not follow the Roman crossing to the right of the river, but stayed on the left riverbank.

[3] Between 1738 and 1739 Davos-based builder Christian Wildener constructed two bridges which crossed the river twice and avoided the worst part of the Roman path on the right riverbank.

[1] From 1818 to 1821 state engineer Richard La Nicca built a completely new road with tunnels connecting the three existing bridges.

[6] Swiss civil engineer Jürg Conzett designed both Traversinersteg bridges, as well as the previously-mentioned Pùnt da Suransuns.
