Railway viaduct of Smržovka
Viaducts – bridges formed with regular arches, were already built by the ancient Romans. You can find them all over the world, some of which have existed for several centuries. When looking at them, not only admirers of technical monuments, but also ordinary tourists hold their breath. Their construction combines power, elegance, history, and in addition they are set in a beautiful natural scenery.
You don’t have to drive all the way to the Alps for beautiful railway viaducts, you can also enjoy them in our country. One of the most beautiful railway viaducts, which is included in the list of national technical monuments, is located in Smržovka on the Liberec – Tanvald line.
The construction of the bridge begun by Italian builders in 1893 was ceremoniously put into operation on October 11 of the following year. The viaduct consists of nine bridge arches, it is approximately 123 metres long and has a maximum height of 26.5 metres. It is built in an arc with a radius of 1800 metres and the width of the bridge deck in the rail bed is 4.9 metres. Quality granite was chosen for the construction, which met the necessary requirements for strength and appearance. An admirable work by experienced Italian bridge builders was in operation without major construction modifications for almost 113 years. At the beginning of the 21st century, water soaked through the masonry, vegetation took roots in the joints and vertical cracks were formed in the masonry of the pillar. As part of the overall reconstruction of the bridge in 2007 and 2008, it was necessary to insulate the granite masonry, repair it by grouting, and place special arch formwork in the place of cracks. As part of the renovation, a new railing was also installed on the outside, thus achieving maximum use of the width of the viaduct.
