A 36-second thrill ride immerses us in a 1973 route to Seattle
By Clay Eals

Homemade time capsules can be uniquely evocative. This I know from the creativity of a long-ago best friend.
Seattle native Mark Tyrrell, a buddy starting when we both were 5 and growing up on Mercer Island, had an offbeat and entertaining affection for our regional milieu, revealing it in unexpected ways.

In the early 1950s, the vortex of the baby boom and long before seemingly everything was digital, our fathers purchased home-movie cameras, captured soundless 8mm vignettes of family events and regularly screened them for us.
At age 22, as shown in this video and in “then” screen grabs (below), Mark took this pastime to the next level.
With his dad’s two-lens Ampro Eight 350 camera — and its “Accurator” viewfinder, with adjustments for light and frames per second — he fashioned a fast-motion film in 1973 that documented the west end of U.S. Highway 10 before completion of its successor, Interstate 90.
In an impossibly swift 36 seconds for a real-time 9-minute journey, his rollicking, windshield’s-eye footage covered 7.2 miles, from Mercer Island’s forested Gallagher Hill Road to the James Street exit of Interstate 5. It’s a westbound thrill ride both startling and smile-inducing, especially for those of us who recall the route.
Therein, coming alive on grainy, color celluloid are many sights that evaporated decades ago, including:
- The thoroughfare at ground level, instead of elevated, sunken in a trench or covered by a concrete “lid.”
- The prominent TraveLodge motel in the Mercer Island business district. (During childhood, I’m embarrassed to say that I took its sign too literally and mistakenly called it the “Trave Lodge.”)
- The Lacey V. Murrow floating bridge, just two lanes each way. Built in 1940 across Lake Washington with a 40 mph speed limit, it featured a midway water pocket for large-boat openings but also a dangerous “bulge” for cars and trucks to navigate.
- The bridge’s equally perilous reversible lanes, with red “X” and green arrow markers that switched during rush hours. Unsafe as well: abrupt pre-tunnel entry and exit turns.
- A pullout lane near Rainier Avenue for crossing against full-tilt traffic (!) to a ramped shortcut to Beacon Hill. (My brother, Doug, recalls a similarly dangerous cross-traffic turn opportunity to reach the upper Shorewood apartments on Mercer Island.)
- A come-to-a-halt stoplight at Dearborn, near Goodwill, on the way to Interstate 5.
- The isolation of downtown’s then-tallest tower, the 1969 Seafirst Building (now Safeco Plaza), “the box the Space Needle came in.”
Sadly, Mark died way too early, at age 46, of myelodysplasia after a dozen years of multiple sclerosis. But his breathtaking mini-travelogue and other filmed and written pieces survive for us to ponder and enjoy.
Today, what Seattle sites do our smartphones and dash-cams record that soon will vanish?

AN APPRECIATION OF MARK TYRRELL:


I worked with Mark at Honeywell Marine Systems Division. He was a wonderful person. When I saw this article today it brought back many memories.
We hippie kids rented a house on Mercer island right next to the approach to the old floating bridge. It was owned by the state in prep for the big interstate.
One winter day in the early 70s it snowed. We decided to walk down the bridge and found ourselves pushing stuck cars up the hill towards the island.
Then the curve right out of the tunnel. OMG so many hit the wall. Yikes.
Plus that bulge and the reversible lane on what my parents called Sunset highway scared the crap out of me.
Thanx for the great memories!!
