VRT Sázava & Sázavka

Both structures are guided by a shared set of principles and constructed from a common family of components, establishing visual consistency across the landscape while simplifying construction and enabling the standardisation of elements. This coordinated approach supports buildability and long‑term durability without compromising architectural clarity.

The viaducts are designed to sit lightly within their valleys, with permanent land take minimised and the landscape allowed to remain legible. Areas required during construction are returned to a natural condition wherever possible. At the low point of the Sázava viaduct, a temporary construction area is reintegrated as a planted retention pond, forming a long‑term environmental asset.

The longer Sázavka viaduct spans a road, railway and river at the centre of the valley, locating the main arch at its lowest point and giving the structure a balanced and composed profile. This arrangement avoids the need for foundations within the constrained corridor between existing infrastructure, reducing excavation and disturbance.

Across both viaducts, wildlife tunnels are incorporated within the approach embankments and hard surfacing is kept to a minimum, supporting ecological continuity and reinforcing a measured, landscape‑led approach to high‑speed rail infrastructure.
