Eastern Washington’s Inner Passage

Note: This isn’t any particular road, but rather a serious of loosely-connected roads that allow one to thread their way through some surprisingly empty country laying between Interstate 90 and WA SR26.

The Inner Passage holds a marked allure for me. Usually, when I am trying to get an event or a function, I’m in a hurry. I want to meet my friends, have supper, and enjoy myself before turning in for a good night’s rest. On the way home, I’m feeling mellow and reminiscent, and that where roads like this one come in.

Westside Military Road

This little stretch of sweepers is quite a bit of fun and a nice way to skirt a large section of Interstate 5. While it’s 35 mile per hour speed limit causes it to be a rather leisurely way to cover this distance, it is also fairly empty and doesn’t appear to be heavily patrolled.

South Military Road route is veritably lined with evergreen trees. I estimate there is at most an eight foot buffer between the road and the forest in most sections. The buffer does help quite a bit in spotting the numerous deer that line the road. If the deer are hiding in the tree line in preparation for their kamikaze dash in front of your bike, you’re going to have very little response time before impact.

One note of caution for those looking to blast down this road at wildly extra-legal speeds, I’ve never seen any evidence of repaving in the years that I’ve been riding this road down to Portland. It looks like a very old alignment of US 99 that has been asphalted over, tar-snaked as needed, and otherwise left to slowly rot in place.

Like Jackson Highway, this road is another great means to avoid the thundering herd on 5 and take a more relaxed 4th-gear approach to traveling. This scenery isn’t spectacular and the service sparse, but your blood pressure will likely be much lower on this road. Just look out for the deer.

As you arrive east of Vader, things are a little different. Starting where Military Road crosses over Route 507, the road changes its name to Westside Highway and is still a state highway in this area. This road is maintained much better, and is far more frequently traveled. Obviously, it has less curves and wider lanes, but is still a pretty good way to avoid the lunacy that is
Interstate 5 in the late afternoon.

As you get to the terminus of SR411 at Kelso, you’ll need to head back east on SR4 to get across the river and back to I-5. If you’re heading south, you can go straight at SR4 and continue skirting around Longview and cross over the Columbia to Oregon via SR433.

U.S. Route 97 (Maryhill, WA to Toppenish, WA)

US97 is a dry side road. It wends its way up from the Columbia along the valley floors, scatterings of abandoned pastureland and hardwood pines punctuating the Eastern Cascade scenery. The views are impressive and the highway is as well-paved as it is desolate on our mid-October weekend excursion.

At one fairly flat spot south of Satus Pass, you can stop at a roadside marker where you can see four of the Cascade Range Volcanoes: Hood, St. Helens, Adams, and Rainier further in the distance. A wide vista of the valley floor, all the way up to the Cascade foothills can be enjoyed there. I highly recommend a short visit, as it’s a good spot to turn around if you want to go through the sweepers again.

Cascade Volcano Viewpoint

View of Mt. Adams from the Cascade Volcano Viewpoint along US97. Very pretty, and a nice place to stop on a very lonely road.

Along Satus Creek and across its namesake mountain pass, the roads curve along the walls of the canyon. The sweeper are clean and infrequently traveled, and the revenue enhancement patrols were simply not in evidence on that sleepy weekend. The few State Patrol cruisers we saw were not very interested even in our fairly elevated speed.

Between Toppenish and Satus Pass, US97 passes through the lands of the Yakama Nation. There are relatively few homesteads along the route and a number of side-roads dead-end about an eighth of a mile from 97. The posted speed of the road is quite liberal for a two-lane US route, and ascends several of the large ridges between the Yakima River and the southern Columbia.

North of Toppenish, US97 is not worth mentioning as it’s an arrow-straight 1960s-era concrete freeway just like any other character-less freeway in the Midwest. North of Union Gap a few miles further, US97 multi-plexes with Interstate 82.

At Maryhill, US97 crosses the Columbia and enters from Oregon, where the average driver isn’t even trusted enough to pump his own gas. Heading west from Maryhill (and where you end up if you miss the left-hand turnoff to cross the Columbia and stay on 97 South) , is Washington SR14. A real gem of a road, and was once a US three-digit route as an alternative to US30/I-82 over on the Oregon side of the river.

This route was largely that taken by Lewis & Clark on their expedition in the very early 1800s, and is known as the Lewis & Clark Highway.

Sagebrush Flats Road

Central Washington’s arid country often appears barren and drab to the casual, unfamiliar eye. But take a ride on some of our backroads and travel against the grain of I-90 and US 2 to find some sweeping vistas, dramatic coulees and even the odd winding road. While most of the farm and range land in this part of the state is transversed by section-line straight roads, there are topographically friendly lines to be found that provide fun rides through beautiful country.

Sagebrush Flats Road is a typical county road in Grant County. Re-surfaced in the last four or five years, it climbs at a moderate rate, north, out of the City of Ephrata over the Beezley Hills into Sagebrush Flats at the Grant County/Douglas County line. This nice stretch intermingles sweeping curves and short straights. The name changes to Rimrock Road as it crosses the county line in the middle of a longer straight away. Up and over the Rimrock area, you drop down into the middle section of Moses Coulee and wind north along the west side of the coulee to US 2. Two sharper curves will make you pay attention, but otherwise it’s nice quick sweepers. There are four cattle guards, but they can be taken at speed as long as they are crossed straight on.

US Route 197 (Central Oregon – The Dalles)

US Route 197 is a rather odd high desert highway. When you’re on this highway riding up on top of the bluffs, it’s quite dull. Seriously, it’s flat, dead-straight, and boring as all get out.

Then you get to the edge of the bluff and there’s a suddenly a sign telling you about a hairpin turn ahead. You go through the turn and look down the length of the valley and see another half-dozen tight corners that are worthy of The Spiral Highway in Clarkston. You polish those lovely curves off, trundle through town, and do another half-dozen or so back up the sides of the valley and back into the flat and dead-straight.

Yes, behind those hills (near Maupin) there’s a dozen or so fabulous twisties. You really wouldn’t know it from here though.

And yes, that speck behind my bike further down the road is a rider turning around to make sure I’m okay. One of three complete strangers on bikes that stopped in the course of my 10 minute photo and hydration break.

North of Maupin are some really great sweeping inclines with passing lanes. On quiet weekdays you can make some serious time for your trip on the roads and still have some fun doing it.
