Question: When did the empire, which was responsible for creating the Nysa Bridge, begin?

<P0-S0> The Cascade Bridge is a historic structure located in Burlington, Iowa, United States. <P0-S1>  In April 1896 the Burlington City Council approved a proposal to have city engineer S.D. Eaton advertise for plans and estimates for a bridge on Main Street that would span Cascade Ravine. <P0-S2>  The Cascade Lumber Company had petitioned for the bridge. <P0-S3>  The city contracted with the Cedar Rapids, Iowa firm of Boynton & Warriner to design the structure and the Milwaukee Bridge and Iron Works to erect the span. <P0-S4>  The city was responsible for building the concrete substructure. <P0-S5>  The bridge was completed in the fall of 1896, and is composed of four spans. <P0-S6>  The span length is 160 ft , and its total length is 464 ft . <P0-S7>  The span is a Baltimore deck truss bridge with Pratt deck trusses at both ends. <P0-S8>  The structure is supported by stone and concrete abutments with concrete pedestals and a single concrete-filled steel cylinder pier. <P0-S9>  Over the years the original deck has been replaced, and concrete has been applied to the stone abutments. <P0-S10>  Otherwise the structure has been unaltered. <P0-S11>  The bridge was listed on the National Register of Historic Places in 1998. <SEP> <P1-S0> Otto Feige (21 September 1882 in Nysa - 2 January 1951 in Kaufbeuren) was an Admiral of the German "Kriegsmarine" (War Navy) during World War II. <P1-S1>  He had initially served in the "Kaiserliche Marine" (Imperial Navy) of the German Empire. <P1-S2>  He was born in Neisse in Silesia on 21 September 1882. <SEP> <P2-S0> The history of the Roman Empire covers the history of Ancient Rome from the fall of the Roman Republic in 27 BC until the abdication of the last Western emperor in 476 AD. <P2-S1>  Rome had begun expanding shortly after the founding of the Republic in the 6th century BC, though it did not expand outside of the Italian Peninsula until the 3rd century BC. <P2-S2>  Civil war engulfed the Roman state in the mid 1st century BC, first between Julius Caesar and Pompey, and finally between Octavian and Mark Antony. <P2-S3>  Antony was defeated at the Battle of Actium in 31 BC. <P2-S4>  In 27 BC the Senate and People of Rome made Octavian "imperator" ("commander") thus beginning the Principate, the first epoch of Roman imperial history usually dated from 27 BC to 284 AD; they later awarded him the name Augustus, "the venerated". <P2-S5>  The success of Augustus in establishing principles of dynastic succession was limited by his outliving a number of talented potential heirs: the Julio-Claudian dynasty lasted for four more emperors—Tiberius, Caligula, Claudius, and Nero—before it yielded in 69 AD to the strife-torn Year of Four Emperors, from which Vespasian emerged as victor. <P2-S6>  Vespasian became the founder of the brief Flavian dynasty, to be followed by the Nerva–Antonine dynasty which produced the "Five Good Emperors": Nerva, Trajan, Hadrian, Antoninus Pius and the philosophically inclined Marcus Aurelius. <P2-S7>  In the view of the Greek historian Dio Cassius, a contemporary observer, the accession of the emperor Commodus in 180 AD marked the descent "from a kingdom of gold to one of rust and iron"—a famous comment which has led some historians, notably Edward Gibbon, to take Commodus' reign as the beginning of the decline of the Roman Empire. <SEP> <P3-S0>  The 100 m long substructure was the second largest of its kind in antiquity, after the Pergamon Bridge. <P3-S1> The Nysa Bridge is a late imperial Roman bridge over the Cakircak stream in Nysa (modern Sultanhisar) in the ancient region of Caria, modern-day Turkey.
