The idea

Vancouver is a city in Clark County, Washington, on the north bank of the Columbia River. It sits directly north of Portland, Oregon, along the state line, and is part of the Portland metropolitan area. Vancouver is also the county seat of Clark County.

The city grew up around Fort Vancouver, an early 19th-century fur trading post. The fort was the main settlement of the British Hudson's Bay Company in the area and the center of the regional fur trade. Indigenous people traded fur pelts at the fort for supplies and trade goods. The fort was named for Captain George Vancouver, a Royal Navy officer and explorer.

The Hudson's Bay Company built the fort in the winter of 1824–1825, and Vancouver was incorporated as a city in 1857. In 1846 Britain signed the Oregon Treaty, which gave the land around the fort to the United States, and the fort later closed. The site has been preserved as the Fort Vancouver National Historic Site, with a full-scale replica of the outpost that is open to the public. The Interstate Bridge carries Interstate 5 across the Columbia River between Vancouver and Portland.

Change

how and why it evolves

Past
Founded around a fur trading post, Vancouver grew from a fort that at its peak controlled 34 outposts, 24 ports, six ships and 600 employees. In 1850 Amos Short named the town Columbia City, and it changed to Vancouver in 1855. Under an act of the territorial legislature, Vancouver was briefly the capital of Washington Territory before that role went back to Olympia. In 1917 the first Interstate Bridge opened and began to replace the ferries that had linked the city with Oregon.
Now
At the 2020 census, Vancouver had 190,915 people, making it the fourth-most populous city in Washington.
Next
As of August 2026, the Interstate Bridge Replacement Program expected to start building a new bridge in 2028, and the new crossing will likely shape how the city grows.
