The hanger arrangement is what separates network tied arch structures from other types of tied arches, such as those with vertical hangers. It is defined by the number of hangers, hanger inclination and hanger distance. A radial hanger arrangement provides an efficient structure, as shown by
Benjamin

Because both the arch and the tie are mainly subject to axial forces, their cross sections can be very small. Usually, transverse bending in the deck is bigger than bending in longitudinal direction. Therefore, a concrete deck that spans between the arches is a good solution for bridges with arch
154:
A drawback to the
Nielsen type is that if there are dynamic loads on the bridge, the tension on some of these hangers may be reduced, even putting the hanger into compression. The network arch type, with multiple crossings, i.e. overlap in the horizontal axis, was developed by Per Tveit to avoid
150:
In Japan, tied arch bridges with crossing hangers are wrongly called
Nielsen-Lohse bridge. Engineer Octavius F. Nielsen applied for a patent on tied arches with inclined hanger rods in 1926. This bridge type was then built about 60 times, primarily in Sweden. None of these bridges had crossed
162:
The correct name of tied arch bridges with inclined hangers that cross each other at most once is
Nielsen bridge. Tied arches with hangers with multiple intersections are network arch bridges. This strict rule is justified, because it leads to a more efficient structure.

Brunn and Frank
Schanack in 2003. In the radial hanger arrangement the distances between the upper hanger nodes and the angle between hangers and arch remain constant. In order to avoid too long hangers this angle may be increased towards the bridge ends.
158:
Lohse bridges have a tie conversely curved to the arch. The bridge deck is supported by a third structural element hanging underneath. They are named for the German engineer
Hermann Lohse (1815–1893) who developed them in the late 19th century.
