Completed in 1993
The viaduct replaced the existing multi‑span arch bridge that has become severely deteriorated. The viaduct has 11 spans, the typical span of length of 48.16 m is formed by two parallel arches. Each arch is assembled from two precast segments connected at the crown with a post‑tensioned concrete joint. The precast segments have a trough cross‑section. Once erected, the troughs were filled with concrete. The deck is assembled from precast girders and a composite slab.
