The PTCT is interrupted through the City of Ellensburg, the largest town on the trail. Central Washington University now stands on the railroad's original route, but the City of Ellensburg has accommodated bicyclists with a route bypassing the busy streets of downtown to connect trailheads at Ellensburg West and Ellensburg East.
Going west to east:
- Turn right onto North Water Street. Use bike lane.
- In 0.6 miles, turn left onto West 7th Avenue. Follow Bike Boulevard signs east on W. 7th Avenue
- In 0.7 miles, turn left onto North Poplar Street. Follow Bike Boulevard sign.
- In 0.1 miles, turn right onto East 8th Avenue. Follow Bike Boulevard sign.
- In 0.1 miles, turn left onto North Alder Street. Follow Bike Boulevard sign.
- In 0.1 miles, turn sharp right onto Palouse to Cascades State Park Trail
Beverly - Smyrna Detour. Due to fire damage of the trestle across Lower Crab Creek, detour using Lower Crab Creek Road which parallels the trail.
Burned trestle over Crab Creek necessitates detour using Lower Crab Creek Road
Royal City Junction-Warden Detour. Tracks remain in place and sections of rail are considered active between Royal City Junction and Warden. There is a 39 mile detour required.
Short detour near Lind due to missing trestle.
Missing trestle at Lind
Cow Creek Detour between Ralston and Marengo due to missing trestle. Steep climbs from the bridge footings, involving 40 feet of vertical rim rock and another 60 feet of steep slope (with rattlesnakes), a creek crossing, and property owners who are strongly opposed to trespassing necessitate this detour. Please respect private property. Dashed gray line indicates unpaved, low traffic roads. Highway 261 has higher traffic, poor sight-lines, and narrow shoulders.
The optional detour ( https://ridewithgps.com/routes/22080463 ) between Ralston and Marengo on low traffic, unpaved roads, bypasses Ritzville. Keep in mind that by bypassing Ritzville, there are NO SERVICES between Lind and Rosalia, other than camping potential in Ralston and Malden. Ritzville offers full services.
Detour options west of Ewan, and Rock Lake Detour due to private property.
As of Spring 2016 State Parks issued this notice: "*Please be aware that the one-mile section of the trail directly West of Ewan currently DOES NOT allow through access, you can contact Todd Dickerson at (509) 648-3626 if you would like to request access". A southern detour using Cayuse Lake Rd parallels the Rock Creek Recreation Area, a scenic alternative, and avoids using Hwy 23.
The trail detour for Rosalia is not necessary, but the detour allows access to services in Rosalia and avoids the up and down required by gaps created by missing trestles. The Tekoa detour is necessary due to closed trestle.
