What would Seattle look like today without Interstate 5 slicing straight through it?
It’s all too easy these days to take for granted the concrete monstrosity that runs through the heart of our city, dividing Seattle into two absurdly disconnected halves like the result of a brain operation gone horribly awry. But there was in fact early opposition to the unfortunate location of I-5 while it was still under construction.
One demonstration of that opposition occurred on the date in focus here, when a group of roughly 100 Seattle residents staged a protest march against the impending construction of I-5 through the city. Since the new freeway was already a done deal at the time, having been previously approved by the Washington State Legislature, the march was aimed at persuading the Seattle city government to construct a lid over the portion of I-5 that would run directly through downtown.
The group consisted mostly of First Hill and downtown neighborhood activists concerned about the negative effects the freeway might have upon the quality of life in the area. Escorted by Seattle police, the group marched along the proposed route of the freeway through a seven-block stretch of downtown, with many carrying placards proclaiming, “Block the Ditch” and “Let’s Have a Lid on It,” among other noteworthy slogans.
Among the organizers of the protest were members of the First Hill Improvement Club and architect Paul Thiry (1904-1993). Best known as the primary architect of the 1962 Seattle World’s Fair, Thiry was also one of the first Seattle citizens to propose a lid over I-5 where new businesses and apartments could be built. Downtown interests also supported the proposed lid, due mainly to their concerns about the loss of parking spaces and the increase in traffic from the freeway. Among other significant local figures who had publicly opposed the freeway route was former Seattle mayor George Cotterill (1865-1958), who was concerned about the potential dangers of building the freeway through a slide-prone area.
This protest was actually an anomaly, and there was in fact minimal opposition to the I-5 route during the early planning stages, since the freeway was planned mostly through quiet bureaucratic process in Olympia until late in the game. The Seattle portion of I-5 began conceptually as the Everett-Seattle-Tacoma Superhighway in 1951, and was approved by the Washington State Legislature in 1953. Funds for construction were provided by the Federal Defense Highway Act of 1956, signed by President Eisenhower.
The Seattle portion of I-5 was completed on January 31, 1967. Although the opposition to its construction was minimal and moot, the damage done to Seattle’s quality of life by its location would soon motivate much more fervent efforts against future freeway construction within the city limits — specifically, against the R. H. Thomson Expressway. That story, told at Radical Seattle Remembers, ended in success when Seattle voters rejected that project in 1972. The lid desired by the June 1961 marchers was finally realized (albeit only in a limited area) when Freeway Park was dedicated on July 4, 1976.
