A typical asphalt speed hump install in 2026 runs $1,500 to $5,000 per unit. The spread comes from six things: profile length (12 ft Watts vs 14 ft sinusoidal vs 22 ft speed table), material (asphalt vs modular rubber), labor (paving crew plus traffic control), pavement marking and signage, multi-unit discounts, and prevailing-wage requirements on city contracts. Most residential single-unit installs in Oregon's I-5 corridor land between $2,200 and $3,800. Below: each cost line broken out, plus where multi-unit projects bring the per-unit number down.
Industry Baseline Range
| Component | Single Unit | Multi-Unit (3+) |
|---|---|---|
| Asphalt material (12 ft Watts) | $400 to $1,200 | $300 to $900 |
| Modular rubber material (12 ft) | $1,200 to $2,800 | $900 to $2,200 |
| Labor (crew + roller + traffic control) | $900 to $3,200 | $600 to $2,200 |
| Pavement marking + signage | $200 to $600 | $150 to $450 |
| Installed total per unit | $1,500 to $5,000 | $1,200 to $3,800 |
Current market reality
Speed hump pricing in 2026 sits at the upper end of historical baselines. Three cost drivers:
- Hot-mix asphalt prices rose roughly 18% from 2024 to 2025 per RSMeans regional data, driven by oil-derivative binder costs.
- Traffic-control labor stays tight in Oregon's I-5 corridor; hourly rates run 12 to 20% above 2023 levels.
- Prevailing-wage requirements on city-contracted work add 25 to 35% to labor lines compared to private-property installs.
The midpoint of the industry baseline still applies, but jobs at the upper end of the range are more frequent in 2026 than in prior years.
What does an asphalt speed hump cost?
A 12-foot Watts profile asphalt speed hump (the residential default) costs $1,500 to $4,500 installed in 2026 for a single unit on private property in Oregon's I-5 corridor. Three line items make up the total:
- Material: $400 to $1,200 for hot-mix asphalt, edge tapers, and pavement preparation. The actual asphalt volume is small (12 ft x 12 ft x 3 in equals roughly 1.3 cubic yards of compacted hot-mix), but mobilization and minimum truck quantities push the line up.
- Labor: $900 to $3,200 for a 3-person crew, paving roller, screed equipment, and traffic control over 4 to 6 hours.
- Pavement marking and signage: $200 to $600 for chevron paint pattern and the W17-1 advance warning sign.
For a deeper material breakdown, see asphalt speed hump cost.
What does a modular rubber speed hump cost?
A 12-foot modular rubber speed hump costs $2,000 to $4,500 installed in 2026 for a single unit. The split:
- Material: $1,200 to $2,800 for the rubber sections, anchor hardware, and reflective tape.
- Labor: $600 to $1,400 for a 2-person crew installing concrete anchors and bolting sections together.
- Pavement marking and signage: $200 to $600 (same as asphalt).
Rubber's installed cost overlaps with asphalt's, but lifespan differs significantly. Rubber lasts 5 to 8 years; asphalt lasts 15 to 25 years. For lifecycle math, see rubber speed hump vs asphalt.
How does length affect cost?
Length scales asphalt cost roughly linearly. The 14-foot sinusoidal and Seminole profiles run 15 to 25% more than the 12-foot Watts. The 22-foot speed table (technically a different device class) runs 3 to 4 times the cost of a 12-foot hump because the device consumes 3 times the asphalt and requires more careful screeding.
| Profile | Length | Installed Cost |
|---|---|---|
| Watts profile | 12 ft | $1,500 to $4,500 |
| Seminole profile | 14 ft | $1,800 to $5,000 |
| Sinusoidal profile | 14 ft | $1,800 to $5,500 |
| Flat-top (speed table) | 22 ft | $5,000 to $15,000 |
How much does multi-unit pricing save?
Multi-unit installs (3+ humps on the same street, same mobilization) typically save 15 to 25% on the per-unit cost. Three line items shrink:
- Mobilization spreads across more units. A single mobilization fee divided across 4 humps drops the per-unit allocation 75%.
- Traffic control runs continuously across the project rather than per-unit. The 6-hour traffic-control labor for one hump becomes 16-hour traffic-control for four humps, not 24-hour.
- Pavement marking can be batched. A single paint crew handles all chevron patterns in one pass.
In a March 2026 install on a Lake Oswego greenway, three asphalt humps installed in one mobilization came in at $2,400 per unit (versus $3,200 per unit for a single-hump install on the same street). The 25% savings paid for the third hump's chevron paint and signage.
What about prevailing-wage city contracts?
City-contracted work typically requires Oregon prevailing-wage rates per ORS 279C (Oregon BOLI Prevailing Wage). Prevailing wage adds 25 to 35% to labor lines compared to private-property installs.
A typical city-funded residential speed hump in 2026 lands at $3,500 to $6,500 per unit installed under prevailing wage versus $1,500 to $4,500 for the same hump on private HOA property. Cities know this; the published budget per hump in Portland's traffic-calming program reflects prevailing-wage rates.
What is the cost to remove a speed hump?
Industry Baseline Range
| Item | Cost |
|---|---|
| Asphalt hump removal (saw-cut + grind + patch) | $1,500 to $3,000 |
| Rubber hump removal (unbolt + repair anchor holes) | $400 to $1,200 |
Removal cost rises if the surrounding pavement requires resurfacing after removal (most asphalt-hump removals do).
How does Oregon city pricing compare to national averages?
Oregon I-5 corridor pricing runs roughly even with the U.S. Pacific Northwest average and 5 to 10% above Mountain West / Texas pricing in 2026. The mix of weather (extended freeze-thaw vulnerability requiring quality binders) and labor cost (Portland metro tradesperson rates) keeps prices firm. National Federal Highway Administration data on traffic-calming device cost ranges supports this regional differential (FHWA Traffic Calming).
Frequently asked questions
How much does a speed hump cost in Oregon? Most asphalt speed humps in Oregon's I-5 corridor cost $1,500 to $4,500 installed for a single unit in 2026. Multi-unit projects bring the per-unit cost down 15 to 25%.
What is the cheapest speed hump option? The cheapest installed option is usually a single-unit asphalt Watts profile on private property without prevailing-wage requirements. Modular rubber sometimes lands below asphalt on labor savings but loses on lifespan.
Why are city-installed speed humps more expensive? Oregon prevailing-wage rates apply to public-works contracts. Labor lines run 25 to 35% higher than private-property installs.
Does the cost include the warning sign? Most quotes do. The W17-1 advance warning sign and yellow chevron pavement marking are standard inclusions in residential speed-hump bids.
Can I get cost-share funding for a speed hump? On public streets, several Oregon cities offer cost-share programs (Portland up to 50%, Beaverton up to 33%). On private property, no cost-share is available; the property owner funds the full install.
