The Maurzyce Bridge over the Słudwia River , a tributary of the Bzura , in central Poland is the world's first fully welded road bridge . It was completed in 1927 shortly after the first welded railway bridge. The bridge is located near the village of Maurzyce near Łowicz in the Łódź Voivodeship .

history

construction

Approximately parabolic upper and straight lower main beams

The bridge was constructed in 1927 by Stefan Bryła , a welding pioneer in construction. Bryła, professor at the National Polytechnic University of Lviv , conducted extensive theoretical studies on the use of welded steel in construction, examining various aspects of acetylene welding and cutting, as well as arc welding . In the mid-1920s, Bryła decided to construct a welded bridge. He took an older, riveted bridge as a model, which he redesigned together with Wenczesław Poniż so that the new construction method could be used. The cross members and some belt elements were redesigned. The design was completed in 1927, i. H. also earlier than that of a similar but shorter, welded railroad bridge from Westinghouse Electric and Manufacturing in Turtle Creek , Pennsylvania , the construction of which progressed faster and opened earlier and is therefore considered the first welded bridge in the world.

The arc welding technology, which was new at the time, enabled a total weight of 56 t in contrast to a conventionally riveted truss bridge with 70 t. Apart from the construction method, it was an ordinary truss bridge with two longitudinal girders made of straight lower and approximately parabolic, polygonal upper main girders. In addition to the two lanes, there were two sidewalks for pedestrians.

The modules were manufactured in the “K. Rudzki i S-ka ” in Mińsk Mazowiecki and then welded together on site. The bridge construction was completed in December 1928 and opened to traffic in August 1929. Although welding was more expensive than the more time-consuming riveting at the time, the overall construction costs were reduced because 17% less steel was used and the construction time was shorter.

Back then, it was considered risky to build a bridge this way. That is why Konstanty Rudzki was chosen as the general contractor and steel constructor . His company, based in Warsaw and with a large factory in Mińsk Mazowiecki, was one of the most experienced bridge construction companies of the time. Founded in 1853, at the transition from the 19th to the 20th century, the company was the only company in Russia that could build difficult-to-build bridges in remote regions. Konstanty Rudzki and his colleagues built almost 20% of all bridges built in Russia at the time.

Later story

The construction of this bridge was 'revolutionary' at the time and the starting point for a new era of bridge construction. The construction method has been described in European and American engineering publications. Engineers from all over the world visited the bridge in large numbers. One consequence of this was that Poland was the first country in the world to set rules for the construction of welded bridges.

Until the late 1970s, the bridge was used by National Road 92 and European Road 8 . When it became too narrow for the traffic, it was moved about 20 meters north in 1977 and closed to road traffic. A replacement bridge was built in their place.

In 1968 the bridge was included in the list of protected cultural assets of Poland by the Monument Documentation Center , the predecessor organization of the Polish National Institute for Cultural Heritage . It was recognized as a historical monument of international importance and later declared an "immovable historical monument".

In 2009 the bridge was overhauled. The steel structure was stripped of rust for 800,000 zł and painted silver. The road surface was replaced by a granite pavement. In 2011 a plaque for Professor Bryła was unveiled in front of it.
