Roman emperor Trajan inaugurates the Aqua Traiana, an aqueduct that channels water from Lake Bracciano, 40 kilometres (25 miles) northwest of Rome.
Emperor Trajan inaugurates the Aqua Traiana aqueduct, channeling fresh water from Lake Bracciano to Rome.
In AD 109, Roman Emperor Trajan celebrated the completion of the Aqua Traiana, a state-of-the-art aqueduct stretching over 40 kilometers. This engineering marvel transported pristine spring water from Lake Bracciano into Rome’s distribution network. Designed to alleviate chronic water shortages, the aqueduct featured a complex system of tunnels, bridges, and arcades. Its construction demonstrated Rome’s mastery of hydraulic engineering and urban planning. The Aqua Traiana augmented public fountains, baths, and private villas across the capital. Trajan’s project remains a testament to imperial investment in civic infrastructure.

First airmail service in Canada from Montreal to Toronto.
Canada's first airmail service took flight between Montreal and Toronto, ushering in a new era of rapid postal communication. The inaugural flight highlighted the potential of aviation beyond military and passenger transport.
On June 24, 1918, a Curtiss JN-4 'Jenny' biplane departed Montreal carrying the first official airmail from Canada to Toronto.
Covering approximately 320 kilometers, the flight took under six hours, a remarkable improvement over train delivery times.
Piloted by Captain Eddie McCurdy, the mission demonstrated the reliability and speed of air transport for civilian mail.
This route laid the groundwork for an expanding network of airmail services across Canada and internationally.
Postal officials hoped the new system would bolster commerce, connect distant communities, and foster national unity.
By the end of the year, Canada was operating several regular airmail routes, signaling the dawn of modern aviation-based postal services.

The Humber Bridge opens to traffic, connecting Yorkshire and Lincolnshire. It remained the world's longest bridge span for 17 years.
The Humber Bridge opens, linking Yorkshire and Lincolnshire with what was then the world’s longest single-span suspension bridge.
On June 24, 1981, the Humber Bridge officially opened to vehicular traffic, spanning the Humber Estuary between East Yorkshire and North Lincolnshire.
At 2,220 meters in total length and with a main span of 1,410 meters, it set the record as the world’s longest single-span suspension bridge for 17 years.
The ambitious project was the vision of local politicians and engineers committed to regional development.
Construction overcame challenges including shifting estuarial tides and soft ground foundations.
Following its opening by Queen Elizabeth II, the bridge transformed transport, drastically reducing travel time and boosting local economies.
It remains an iconic feat of British civil engineering.
