For the most part, arch bridges are manufactured in glulam which is bonded and stabilised transversely using rods or frames. As a rule, for transport and manufacturing reasons, three-section arches are used for large span widths.

From the static perspective, three-hinged arches are advantageous and facilitate making torque rigid assembly joints on the construction site. For smaller spans, the arches can be manufactured in one piece as two-section arches.

Arch bridges can have a supported or suspended bridge deck. The road surface is made of asphalt, gravel or wood. Dimensioning and surface treatment are executed in accordance with the current Swedish bridge standard and the service life is 80 years.
