Part of a Bigger Road Trip

We didn't come to Penstock Bridge as a destination by itself.

It was one of those wonderfully unplanned—or at least loosely planned—stops that make a good road trip what it is.

We were making our way east on US 2 toward Leavenworth, as part of a full-day loop that would eventually take us over Blewett Pass, through Cle Elum, across Snoqualmie Pass, and home again.

The Jaguar F-Type R was along for the ride, which made the mountain roads every bit as enjoyable as the destinations themselves.

By the time we reached Penstock Bridge, we'd already been through Index, stopped at the Espresso Chalet, visited Deception Falls, and climbed toward Stevens Pass. Penstock Bridge gave us another reason to pull over, get out of the car, and explore a little.

And that's really what this trip was about.

Not rushing from one destination to another, but seeing what we could find along the way.

The Penstock Bridge and Old Pipeline Bed Trail turned out to be exactly the kind of stop we enjoy—interesting, easy to explore, and just unusual enough to make you glad you decided to pull over.

Afterward, we continued on to Leavenworth for lunch before heading up Icicle Road and eventually making our way toward Blewett Pass.

Want to See the Whole Trip?

Penstock Bridge was just one stop on our Route 2 to Leavenworth, Blewett Pass & Home Again road trip.

The complete route included mountain roads, waterfalls, Bigfoot, Leavenworth, Icicle Road, the old mining town of Liberty, Blewett Pass, Cle Elum and Snoqualmie Pass.

It's a good example of why we like road trips where the road itself is part of the destination.

Sometimes you don't really know what you're going to find until you pull over.

🥾 What It Is

This riveted steel Baltimore Petit truss was built in 1909 by the Great Northern Railroad Company as part of the Tumwater Hydroelectric Plant. The hydroelectric installation, which was an extensive system that required conductors and additional power stations, was built to power the Great Northern trains over a 57-mile mountain division from Leavenworth to Skykomish. The water, which was the power source for the electrification of the tunnel, was transported approximately two miles by a penstock from a 250-acre storage site to the powerhouse. The seven-panel bridge was constructed to carry the 8.5-foot-diameter penstock from the south bank of the river to a surge tank at the corner of the powerhouse. Most of the penstock was wood stave pipe; however, the last 952 feet of pipe, part of which passed through the bridge, was constructed of riveted steel. The penstock pipe through the bridge has been cut, to enable the bridge to be used as a pedestrian walkway. The bridge is one of the early examples of a riveted steel Baltimore Petit truss and remains as one of the few extant reminders of the early attempts to electrify the railroads through the Cascade Mountains.
