Władysław Tryliński

Władysław Tryliński (20 June 1878 – 6 February 1956) was a Polish transportation engineer and inventor. He is best known for the creation of ''trylinka'', the hexagonal concrete block used for pavements and to strengthen embankments, and the design of the Maurzyce Bridge, the world's first welded road bridge.

Early life and education

Tryliński was born in Telšiai, then part of the Russian Empire's Kovno Governorate, to Antoni Tryliński, a military officer from a Pułtusk family, and Agnieszka ().

After graduating from the in Warsaw in 1896, he studied for a year at the physics and mathematics department of Saint Petersburg University, and in 1902 graduated from the Tsar Alexander I Institute of Transportation Engineers (present-day St. Petersburg State Transport University) in Saint Petersburg.

Career

After the graduation, Tryliński worked in Yekaterinburg in the design team of the Black Sea Railway. In 1904, he began to work in the Vilnius District of Communication Roads, directing constructions of about 200 road bridges and replacements of wooden bridges and culverts with those made of more durable materials—mostly reinforced concrete.

During the First World War, he directed road works for the army in Chișinău and Pskov with the rank of general (1915–1917). In 1918, he was the head of the technical division of General Józef Dowbor-Muśnicki's I Eastern Corps in Babruysk. After Poland regained its independence in the early 1920s, he became the director of Public Works at the District Directorate of Public Works of the Warsaw Province, and after reorganisation, the head of the communications and construction department at the Warsaw Provincial Office. For his professional and scientific achievements, he was awarded the Officer's Cross of the Order of Polonia Restituta on 31 December 1923.

In 1929, together with Stefan Bryła, Tryliński became famous for the design of the Maurzyce Bridge, the world's first welded road bridge, which was erected across the Słudwia River in Maurzyce near Łowicz, Poland. On 24 April 1933, Tryliński received a patent for "driveways and sidewalks made of hexagonal concrete slabs". The hexagonal tile was named ''trylinka'' after him and widely used in the construction of new roads in interwar Poland due to its low cost and durability—becoming a synonym for sidewalks made of them.

From 1925 to 1936, he was president of the Union of Road Engineers. After the Second World War, he worked at the Ministry of Transportation, including evaluating projects for the construction of the Warsaw W-Z Route and the reconstruction of the Warsaw railroad junction, and from 1951 until his death in 1956, at the Ministry of Road and Air Transport. He received a patent for reinforced concrete railway sleeper on 12 February 1953.

Tryliński died in Warsaw and buried at Powązki Cemetery.
