Bridge over Savinja in Laško

The 123 meters long bridge spans the Savinja River with two asymmetric spans of 75 and 48 meters and one river support, located outside the main watercourse on a gravel deposit formed as a hydraulic consequence of the river current flow.

The bridge connects the main Laško – Šmarjeta road on the right bank of the Savinja River with the Laško – Šentjur road on the left. The bridge will significantly divert heavy freight transport, serving the Pivovarna Laško brewery, from Laško’s centre.

The bridge's design has a negligible impact on the river current and preserves the cultural heritage of the veduta to the church in Marija Gradec. Ponting designed the bridge as a continuous prestressed frame structure over two fields with a box-shaped cross-section of variable construction height and an asymmetrically placed river support. Within the project, we also designed a larger anchored retaining wall, ensuring the stability of an extensive cut along the reconstructed main regional road behind the bridges western approach.

The construction of a new bridge over the Savinja River in Laško began in mid-July 2019 and opened to traffic in February 2021.
