Borovský most (Zatopený dálniční most přes Sedlický potok) - Vodní Nádrž

A super mystical place, Hitler's unfinished highway, which ends in the middle. Very interesting place, no one was here at the time of our visit. Due to the fact that the building is over 70 years old and without any maintenance, the bridge is in surprisingly good condition. It is currently located in the 1st protection zone, due to water protection. ?

Originally a bridge over the valley on the planned highway, now absurdly terminated over the dam. Which was not there originally. History: 25 m high arch bridge over the valley of the Sedlický stream. The bridge whose construction began in July 1939 was built by the company Ing. Jakub Domanský, the construction was led by Ferdinand Čulík. The bridge was designed as a pair of identical arch bridges, each with a separately tilted roadway, as the highway route was to turn south behind the eastern end of the bridge. The building was built even after the war by the company Ing. Jakub Domanský, but already as the Czechoslovak Construction Works - the national enterprise SVIS plant. In 1949, the arch of the left bridge was concreted, and by 1950 the bridge was almost completed. At the eastern end of the bridge, it was left to create an earth embankment, along which the body of the highway would continue. The construction of the bridge was approved in December 1952, but due to the abandonment of the concept of motorways in Czechoslovakia, the sections under construction were abandoned. In 1963, a road network was selected for priority modernization, and at the same time the shape and scope of the motorway network were determined. In 1967, the construction of the D1 Prague – Brno motorway was started, the route of which, with few exceptions, copied the plans and parts under construction from the 1940s. These exceptions included the bridges near Borovsko and Hulice, due to the construction of the Švihov Reservoir on the Želivka River, intended for the supply of drinking water to the capital city of Prague and its surroundings. Filling the reservoir would mean flooding almost the entire bridge over the Sedlický stream, for which the bridge structure was not designed. Several solutions have been proposed, including treatment of both bridges against the effects of water, reduction of the maximum level of the reservoir or their combination. Due to the growing need for drinking water, the option of not using the full capacity of the waterworks was rejected, which would bring high costs for the treatment of the Borovský Bridge, which was to be almost completely flooded. This variant also brought the risk of contamination of the drinking water source from a large number of vehicles passing on the motorway, which is only two meters above the level of the dam. Therefore, it was decided to move the route of the D1 motorway less than a kilometer further south.
