Mirna Bridge, Concrete girder bridge on A9 motorway in Istria, Croatia
Mirna Bridge is a concrete motorway crossing in Istria that spans the Mirna River valley with 22 different spans. The structure was built with substantial support pillars to handle the challenging ground conditions found in this region.
The crossing opened in 2005 as part of regional motorway expansion, connecting previously separated areas more directly. It represents a key moment in modernizing transportation links across Istria.
The bridge passes over the Mirna River valley, where local stories tell of ancient giants who constructed towns using massive stones.
This is a toll motorway section that operates year-round with noticeably heavier traffic during summer months. Visitors should expect travel times to vary significantly depending on the season and time of day.
The bridge's construction required specific adaptations to poor soil conditions, resulting in piers ranging from 13 to 40 meters in height.
