Viadukt Křenová, Railway viaduct in Brno-město, Czech Republic

Viadukt Křenová is a stone railway bridge of 37.20 m length and 16.50 m width at the northern throat of Brno main station, carrying the line to Česká Třebová over Křenová street. Six segmentally arched openings span about 6 m in height, with sandstone-block piers and abutments; the two central passages carry the tram since 1901, the flanking ones road traffic, and the outer ones pedestrians. A separate single-track riveted steel bridge with cast-iron columns stands beside it.

The viaduct was built between 1847 and 1848 by the Gebrüder Klein company as part of the Northern State Railway linking Brno to Česká Třebová. It was later expanded to accommodate additional railway connections in the region.

The unofficial name comes from Křenová street, which passes beneath the arches; the viaduct itself has no official name and is recorded as bridge at km 155.892. The central openings have carried the tram line since 1901, while the outer arches are reserved for pedestrians. The adjacent single-track steel bridge rests on decorated cast-iron columns.

The viaduct crosses Křenová street at the northern throat of Brno main station, where the line to Česká Třebová passes over the road. The two central arches carry the tram line (since 1901) and trolleybus wires (since 1949), while the outer arches are for pedestrians. Walk through the side passages on foot to see the sandstone piers up close.

The viaduct was expanded from three to five tracks in 1870 to create a new connection between the Lower and Main stations. This expansion demonstrates how railway infrastructure quickly adapted to growing traffic demands.
