Crosswalk installation in Sherman County is sparse, focused, and seasonal. Sherman is Oregon's smallest-population county, with the wheat-haul economy and a handful of small downtown grids defining the demand. Moro, the county seat, anchors the network with its courthouse and school campus. Wasco, Grass Valley, Kent, and Rufus fill out the I-84 corridor and the OR-97 spine running north-south through the Columbia Plateau. Wind farms across the eastern ridges add private-property crossings tied to facility entry roads. Cojo schedules Sherman County crosswalk work into the dry Columbia Plateau summer paint window, runs MUTCD-compliant ladder and parallel-bar patterns, and installs ADA detectable warning surfaces at every curb ramp. Mobilization out of The Dalles keeps travel reasonable.
Moro, Wasco, Grass Valley, and the Small-Town Grid
Moro, the county seat, sits at the OR-97 / OR-216 junction in the wheat country. Its downtown is a few blocks of historic commercial buildings centered around the courthouse, the Sherman County Historical Museum, and the Sherman County School. Wasco to the north along OR-97 (not to be confused with the larger Wasco County to the west) runs a one-block downtown plus a few commercial properties on the highway frontage. Grass Valley to the south of Moro runs an even smaller downtown grid. Rufus sits at the I-84 / John Day Dam crossing and serves as the county's I-84 frontage point.
State-highway frontage on US-97 and I-84 frontage at Rufus triggers ODOT Region 4 coordination for any in-roadway crosswalk work. Side-street crossings off the state route stay under Moro, Wasco, Grass Valley, or Rufus city right-of-way (each runs its own small local permit cycle). For full lot-marking scope across the same sites, our parking lot striping in Sherman County page covers the package.
Sherman County School and Other Public Facilities
Sherman County School District operates one consolidated K-12 campus in Moro that serves the entire county. The campus has school-zone yellow crosswalk overlay requirements with advance-warning markings on the approach. The yellow overlay paint cures under the same 50 degrees F pavement temperature and dry-surface rules as standard white traffic paint. The Sherman County courthouse complex and the county fairgrounds (on the Moro outskirts) each run a small set of ADA crossings tied to facility entry walks. Wind-farm operator access points across the eastern ridges sometimes include private crosswalks at their gate and visitor-center entries -- those are private-property work outside the public right-of-way permit cycle.
ADA detectable warning surface placement is standard at every curb ramp tied to a marked crossing. Older Moro and Wasco crossings without compliant truncated dome pads get the upgrade as part of any re-stripe scope.
Columbia Plateau Climate and Paint Cure
Sherman County sits at 200 feet along the Columbia River at Rufus, climbing to 1,800 feet at Moro and higher in the southern wheat country. Winters are cold and windy -- the Columbia Plateau wind can drop wind-chill below the paint adhesion threshold even on otherwise sunny days. Summers are hot, dry, and high-UV. The traffic paint window opens reliably in mid-April and stays open through October. Within that window, the Columbia Plateau wind actually helps cure -- it dries surfaces fast after morning dew and accelerates waterborne paint set time.
UV intensity on the plateau shortens paint service life compared to valley conditions. Plan crosswalk refreshes every two to three years on the limited heavy-traffic downtown corners and three to four years on rural school and residential crossings. Bundling crosswalk paint with sealcoating in Sherman County on the same site visit keeps both surfaces on the same refresh calendar and saves a mobilization charge.
MUTCD Patterns for Sherman County
The Manual on Uniform Traffic Control Devices defines the legal crosswalk patterns. For Sherman County's sparse rural-plus-wheat-country mix:
- Standard parallel-bar -- residential streets, rural-route crossings, the small downtown grids
- Ladder-bar -- the Sherman County School zone yellow overlay, the courthouse approaches, the rare higher-volume corner
- Continental crosswalk -- rare in Sherman County, reserved only for facility-entry private crossings where the property owner wants maximum visual cue
For the full pattern selection logic and ODOT overlay, Oregon parking lot striping regulations covers the state-level rules.
Industry Baseline Range -- Sherman County Crosswalk Installation
Industry Baseline Range
| Scope | Typical Output | Baseline Cost |
|---|---|---|
| Single parallel-bar crosswalk (10 to 12 ft wide) | one crossing | $150 to $350 |
| Ladder-bar crosswalk (10 to 12 ft wide) | one crossing | $300 to $600 |
| Continental crosswalk (10 to 12 ft wide) | one crossing | $400 to $750 |
| School-zone yellow overlay | per crossing | $75 to $200 |
| ADA detectable warning surface (24 in by 48 in) | per pad | $250 to $550 |
| Thermoplastic upgrade (per crossing) | one crossing | $800 to $1,800+ |
Current Market Reality
Sherman County is sparse enough that single-job mobilization rarely pencils. The way to get fair pricing in this county is to combine the Moro school-zone refresh, the courthouse upgrades, the Wasco and Grass Valley downtown stripes, and any wind-farm facility crossings into one summer trip. Mobilization out of The Dalles or Hood River cuts travel time substantially compared to a Portland-based contractor. Bundling crosswalk work with asphalt paving in Sherman County or any Rufus-area I-84 frontage paving keeps cost down.
ODOT Region 4 and Local Permitting
State-highway crossings on US-97, I-84 frontage at Rufus, OR-216, and OR-218 (heading into Wheeler County) require ODOT Region 4 permits and approved traffic-control plans. City crosswalks off the state route stay under Moro, Wasco, Grass Valley, or Rufus local right-of-way. Sherman County Public Works handles the rural-route system. A complete bid for any state-route scope includes the ODOT permit, traffic-control plan, and flagger crew on the bid line.

Cojo runs Sherman County crosswalk work inside the Columbia Plateau summer paint window, mobilizes out of The Dalles or Hood River, and handles ODOT permitting on US-97 and I-84 frontage. ADA detectable warning pad installation, school-zone overlays at the Sherman County School, and MUTCD-compliant ladder and parallel-bar patterns are all part of the standard scope.
