A raised crosswalk is a hybrid speed-table and crosswalk where the pavement is elevated 3 to 4 inches above the surrounding roadway and the elevated surface is striped as a continental crosswalk. Per the ITE Traffic Calming Manual, ramps approaching the elevated platform should rise on a 1:10 to 1:20 grade over 6 to 12 horizontal feet, and the platform itself should span 10 to 16 feet in the direction of travel. Operating-speed reductions of 30 to 50 percent are typical. ADA accessible-route requirements force the platform top to remain flush with the adjacent sidewalk, eliminating the need for a curb ramp at the crossing.
Below we cover the design spec, the drainage and access trade-offs, and a Cojo install reference for raised-crosswalk projects across Oregon.
What Is a Raised Crosswalk?
A raised crosswalk is a flat pavement platform elevated above the roadway, with painted crosswalk bars on the elevated surface. Drivers experience the platform as a speed table — the rise forces them to slow before the crosswalk to avoid undercarriage scrape. Pedestrians experience the platform as a flush continuation of the sidewalk, with no curb to step down.
For a head-to-head comparison with traditional flush crosswalks see raised vs flush crosswalk traffic calming.
Why install a raised crosswalk?
Three reasons:
- Speed reduction. ITE field studies show 30 to 50 percent reductions in 85th-percentile speed at the crossing.
- Pedestrian visibility. Elevated pedestrians appear at a higher driver eye-level than flush pedestrians.
- ADA continuity. No level change between sidewalk and crossing means no curb ramp needed at the crossing itself — though detectable warnings are still required at the platform-to-roadway edges.
The trade-off is cost (typically 5 to 8 times a flush continental crosswalk) and impacts on bus, emergency-vehicle, and snowplow operations.
What Does ITE Recommend for Geometry?
The ITE Traffic Calming Manual sets the dimensional rules:
| Element | Specification |
|---|---|
| Platform height | 3 to 4 inches above roadway |
| Platform length (direction of travel) | 10 to 16 ft (10 ft minimum) |
| Ramp grade | 1:10 to 1:20 (5 to 10 percent slope) |
| Ramp horizontal length | 6 to 12 ft each side |
| Total platform footprint | 22 to 40 ft length × full street width |
| Crosswalk pattern on platform | Continental, 12 to 16 ft wide |
| Platform color contrast | Recommended (red brick stamp, or asphalt-color delineation) |
What slope is best for typical urban arterials?
For collector roads with bus service, 1:15 ramp grade with 12-foot platform length is the typical ITE-recommended target. This gets a meaningful speed reduction (35 to 40 percent) without making the bus lurch through the platform.
What Are the ADA Conflicts?
Why does ADA complicate raised crosswalks?
The platform top is flush with the adjacent sidewalk, which simplifies the pedestrian path. But:
- Detectable warnings are still required at the platform-to-roadway edge per ADA Standard 705. Sight-impaired pedestrians need to feel the boundary between the safe platform and the roadway. See our ADA crosswalk detectable warning curb cut spec for placement details.
- Drainage must not pond at the ramp toe. Standing water creates a slip hazard and crosses 2 percent ADA cross-slope limit.
- Cross-slope of the platform top must stay at or below 2 percent for ADA compliance.
The most-failed ADA element on raised crossings is detectable-warning placement at the platform edge. The warning panel must span the full width of the pedestrian path and sit at the actual platform-to-roadway transition, not somewhere on the sidewalk-platform boundary.
What About Bus, Emergency, and Snowplow Operations?
How does a raised crosswalk affect buses?
Bus operators report two complaints on raised crossings: passenger discomfort (lurch effect) and floor wear (suspension cycling). 1:20 ramp grades with 14-foot platforms minimize both. ITE recommends consultation with the local transit authority before designing on any signed bus route.
What about fire and ambulance?
Emergency response time can stretch by 1 to 3 seconds per crossing. Most jurisdictions cap raised crossing density to no more than two per mile on any route used by ambulance or fire response. Cojo coordinates with the local fire chief during design on every Oregon raised-crossing project.
What about snowplows?
Snowplow blades scrape platform tops and erode the leading edge of ramps. Most Oregon raised crossings use a hardened-asphalt or concrete platform top to resist plow damage. Bend, La Grande, and other high-snow jurisdictions often opt for flush crossings with RRFBs instead, accepting the speed-reduction trade-off.
How Are Raised Crosswalks Marked?
What pattern goes on the platform?
Continental, every time. Wide white longitudinal bars (24-inch width, 24-inch gap) on the platform top, painted in preformed thermoplastic for durability. Most jurisdictions also stamp or color the platform itself in red brick or contrasting asphalt to signal the elevated transition before the painted bars come into the driver's view.
What does FHWA say about raised crossing markings?
FHWA's Pedestrian Safety Strategic Plan endorses raised crossings as a high-effectiveness countermeasure when paired with continental markings, advance signage, and proper sight distance. The strategic plan calls out raised crossings as one of the top-tier countermeasures for hospital and school crossings.
What Does a Real Cojo Raised Crosswalk Project Look Like?
In June 2025 our crew installed a raised continental crosswalk at a Bend community college campus on Awbrey Butte Road. Platform was 12 feet long × full 36-foot street width, 3.5-inch rise on 1:15 ramps, with stamped red-brick concrete platform top and preformed thermoplastic continental bars. Detectable-warning panels at both platform edges. Local fire and Cascades East Transit signed off the design before construction. Operating-speed reductions measured at 36 percent on the post-install survey. Total project: 14 crew-days, 78,000 dollars including concrete platform, ramps, drainage, markings, and signage.

Industry Baseline Range
| Component | Industry Baseline Range |
|---|---|
| Concrete platform + ramps (full crossing) | $35,000 to $90,000 |
| Asphalt platform + ramps (full crossing) | $20,000 to $55,000 |
| Continental thermoplastic markings on platform | $1,200 to $2,500 |
| Detectable warning panels at platform edges | $1,800 to $4,500 (both edges) |
| Drainage modifications | $4,000 to $18,000 |
| Total raised crosswalk project | $35,000 to $120,000 |
Current Market Reality
Concrete prices are up 8 to 14 percent annually since 2023. Stamped-brick concrete adds 25 to 40 percent over plain concrete. Detectable-warning panel costs are up 15 percent. Most Oregon raised-crossing projects qualify for HSIP or TAP funding when crash history justifies the install.
How Cojo Approaches Raised Crosswalk Projects
We scope raised crossings as full-system engineering projects: warrant memo, geometric design, drainage analysis, fire and transit coordination, platform install, ADA detail, and markings. Most of our raised-crossing work is on hospital, school, and university campuses where the speed-reduction case is strong. To start a project, see crosswalk installation Bend Oregon or contact Cojo.

Frequently Asked Questions
How tall should a raised crosswalk be? 3 to 4 inches above the surrounding roadway per ITE Traffic Calming. Lower than 3 inches and the speed-reduction effect disappears; higher than 4 inches and the platform stresses bus and emergency-vehicle suspensions excessively.
What ramp slope should approaching vehicles see? 1:10 to 1:20 grade. 1:15 is the typical urban-arterial target — a 4-inch rise over 5 feet of horizontal ramp. Steeper ramps reduce speeds more aggressively but punish buses and trucks.
Are raised crosswalks ADA-compliant? Yes when designed correctly. The platform top is flush with the sidewalk, eliminating the curb-ramp requirement at the crossing. Cross-slope must stay at or below 2 percent and detectable-warning panels are required at the platform-to-roadway edges. See ADA Standard 705 for warning-panel detail.
Can a raised crosswalk be on a bus route? Yes with care. ITE recommends 1:20 ramp grade on signed bus routes to minimize passenger lurch. Consult with the local transit authority before design. Some jurisdictions limit raised crossings to no more than two per mile on bus routes.
How much does a raised crosswalk cost compared to a flush crosswalk? 5 to 8 times a flush continental thermoplastic crosswalk. A typical urban raised crossing runs 35,000 to 90,000 dollars including platform, ramps, drainage, ADA detail, and markings. The flush continental equivalent is 4,500 to 9,500 dollars. The cost gap is the price of speed reduction.
