Railway bridge in Úvaly, Railway bridge in Úvaly, Czech Republic.

The railway bridge in Úvaly is a structure of sandstone and granite blocks spanning the Výmola river valley. The original construction from 1844 runs alongside a later concrete bridge, and together they form a double railway crossing today.

Jan Perner, the chief engineer, designed this section of the Prague-Kolín railway line in 1844 as part of a new transport connection. In 1954, a second concrete bridge was added to handle growing rail traffic.

Locals call the bridge Devět kanálů, "Nine Channels", after its nine arches. The name does not come from the Výmola river it crosses. A time capsule placed in a pillar on 11 November 2015 by the town mayor holds period banknotes, newspapers, a message from the mayor and the sheet music of songs by the Úvaly band Divokej Bill.

A paved asphalt path now runs under the bridge along the Výmola stream, leading to Riegerova Street near the primary school at the end of the square. The bridge is on an active railway line, so access to the tracks is not permitted. The best views of the twin structures are from this path and from the surrounding valley floor.

The stone construction from 1844 and the concrete bridge from 1954 stand side by side, allowing travelers to see two generations of engineering technique at once. This side-by-side arrangement shows how building methods evolved over a century.
