After returning to Rome, Trajan celebrates a Triumph for his victory over the Dacians. He was keenly aware of the lack of total victory and the need to prepare for a potential second war. Trajan instructs his chief architect, Apollodorus of Damascus to build a bridge across the Danube River. Construction starts this year and will take two years to complete. At completion Trajan's Bridge will be 3,742 ft long, and will hold the record of the longest bridge for almost 1,000 years. The bridge wasn't the only preparation that the Romans took for a potential campaign, and canals were dug to bypass rapids and allow ships to navigate the river
