This Friday, take a scenic drive up the coast when 101 at 100: The History of Oregon’s Most Iconic Highway opens at the Oregon Historical Society in downtown Portland. On view through October 11, this interactive installation explores a century of transportation, culture, and coastal life shaped by one of Oregon’s most beloved roads.

Stretching 363 miles along the Pacific Coast, U.S. Highway 101 has connected communities from Astoria to Brookings since its designation as a federal highway in 1926. 101 at 100 traces the road’s evolution from Indigenous travel routes to a vital corridor for commerce, tourism, and daily life.

“Having grown up on the Oregon Coast in Reedsport, Highway 101 was a constant presence in my life,” said OHS Boyle Family Executive Director Kerry Tymchuk. “This exhibition invites visitors to discover the rich diversity of Oregon’s coastal communities and to appreciate the remarkable feat of engineering that made Highway 101 possible.”

In conjunction with the main exhibition, visitors can also see From Highway 101: Images of Oregon’s Most Iconic Highway, a supporting photographic exhibition by local photographer Peter Marbach. This visual celebration offers contemporary views of life along the coast — from majestic bridges and misty shorelines to the vibrant communities that line the highway — serving as a love letter to the road on its centennial.

Visitors can see both exhibitions for free opening weekend, as OHS will offer free admission February 13–15, in honor of Oregon’s 167th birthday (February 14).

The Oregon Historical Society’s museum is open daily in downtown Portland, from 10am to 5pm Monday through Saturday and 12pm to 5pm on Sunday. Admission is free every day for youth 17 and under, OHS members, and residents of Multnomah County. Learn more and plan your visit at ohs.org/visit.

About Highway 101

Since time immemorial, people have lived and traveled along Oregon’s coast. Native people used waterways, beaches, and extensive trail networks for travel and trade. In the 19th century, non-Native migrants settled along the coast, constructing makeshift roads of sand, wood, and gravel to navigate a stunning but isolating landscape of cliffs, forests, and windswept beaches.

As automobiles gained popularity in the early 20th century, the coast’s isolation became a barrier to travel and economic growth. In response, Oregon leaders formed the Oregon Highway Commission in 1913, launching an ambitious effort to build a coast highway. Completed over a decade through remarkable feats of engineering, the 363-mile road became U.S. Highway 101 in 1926, linking communities across seven counties. This exhibition traces how this iconic highway reshaped the coast and asks visitors to consider how movement, access, and infrastructure continue to influence who can travel, live, and thrive along Oregon’s shores.
