It spans the Ganter River valley and is located along the Simplon Pass road about 10 km (6 mi) south of Brig in the canton of Valais, Switzerland.

[4] The bridge's form consists of an S-curve roadway, high above the Ganter River and at about 1,450 m (4,760 ft) above sea level, supported by two main towers and five smaller piers.

[4] From some drivers' view, these triangular concrete walls plus the one across the top of the towers made the main span feel too much like a tunnel entrance.

In the words of David P. Billington: “Ganter bridge ... represents one of those rare events where a new form arises”.

The locations of the piers were based on geological conditions as well as symmetry and uniformity of span lengths.
