The Great Plank Road

By 1851, a dirt road, which was often muddy, ran between Portland and the Tualatin Valley—starting on Jefferson Street at the Willamette River then passing through Tanner Creek Canyon that cuts through the Tualatin Mountains. A plank road was suggested by Portland entrepreneur and proprietor Daniel H. Lownsdale as a means to transport abundant Tualatin Valley farm produce and grains to California Gold Rush-inflated markets in San Francisco, California. Col. William Williams Chapman, another proprietor, expended time and expense providing the basics for fledgling Portland in an effort to counter competition by other upstart towns and Hudson's Bay Company. He founded ''The Oregonian'', enlarged Portland's platt, improving the city's streets, and ushered construction of Canyon Road. Others already invested in the city contributed to help make Portland the prime seaport of the region, including persuading others to join them, removing river obstructions, and importing goods from Asia and beyond. The Portland & Valley Plank Road Company was chartered in January 1851 by the Oregon Territory, territorial government. Editor of the ''The Oregonian, Weekly Oregonian'' newspaper, Thomas J. Dryer, immediately invested $500 and promoted the project. Stephen Coffin and William W. Chapman pledged $3000, with Daniel H. Lownsdale pledging $2,000. Ultimately over $35,000 was pledged but not all was paid, with Coffin, Chapman and Lownsdale likely to have not paid in full. Coffin gave the contract to a sawmill owned by himself and Simeon Reed, and the first plank was laid on September 27, 1851, leading to a large celebration. By November 1851, less than $3,000 in pledges had been collected, while $11,000 had been spent. The road had progressed fewer than three miles. The route, however, was excavated, following the canyon of Tanner Creek on the east side of the Tualatin Mountains. By spring of 1852, just over $6,000 had been collected and $14,000 spent, leading to the replacement of management and directors. The project remained incomplete for three years until Supreme Court Justice Cyrus Olney required subscribers to pay at least 80% of the pledged amount. Back wages were still owed by December 1855, leading Olney to demand full payment from subscribers and for county sheriffs to find delinquent subscribers. On January 25, 1856, the territorial government hired a new company to complete the road, and the city's merchant leaders (including William S. Ladd and Josiah Failing) raised $75,000 for the new Portland and Tualatin Plains Plank Road Company, finishing the road by the end of 1856. The road, though never completely planked, was favored by farmers of Polk County, Oregon, Polk, Yamhill County, Oregon, Yamhill, and Washington County, Oregon, Washington counties since it saved between three and ten miles (16 km) travel to the next nearest ports at St. Johns, Oregon, St. Johns and St. Helens, Oregon, St. Helens, but on a rough muddy road through deep woods. Harvey W. Scott said this new toll road was still difficult for travel and the entrance was "almost inaccessible", but the road was finished. Part of Highway 26 now passes through Tanner Creek Canyon—the canyon near the Oregon Zoo as the highway approaches Portland's Goose Hollow, Portland, Oregon, Goose Hollow neighborhood via the Vista Ridge Tunnels. However, Tanner Creek Canyon was originally a much deeper and narrower ravine. In the early twentieth century, when Tanner Creek was buried as it passes through Tanner Creek Canyon, the canyon was enlarged and infilled to raise Canyon Road. Then, in the 1960s when I-405 was being constructed, the excavated dirt was trucked into the canyon to further expand and fill Tanner Creek Canyon. In August 2015, remnants of the Great Plank Road were unearthed during a road widening project in Beaverton. The pieces weren't salvageable.


Route

The historic route is almost completely paved over by modern roads. Beginning at Goose Hollow near where the Vista Bridge is now (), Jefferson Street transitions into Canyon Road, both in street signs and modern maps. It went up the canyon behind the Vista Ridge Tunnels where the Sunset Highway (Oregon), Sunset Highway—also known as U.S. Route 26 (Oregon), U.S. Route 26—goes over Sylvan hill. Slightly west of Sylvan, an interchange with modern Canyon Road, also known as Oregon Route 8, continues southwest into Beaverton. Two blocks west of Cedar Hills Boulevard, at the junction with Hocken Road (), the contemporary road name changes to Tualatin Valley Highway ("TV Highway", though the original plank road continued farther west. A plaque to commemorate the road was placed in the South Park Blocks by the Lang Syne Society in 1991.
