Speed humps are typically priced per linear foot of lane width because the hump's length in the direction of travel (12 to 14 ft) is fixed by the device class but the lane width across the road varies from 8 to 14 feet. A residential street with a 12-foot lane needs 12 linear feet of hump material; a wider 24-foot two-lane street needs 24 linear feet. In 2026 Oregon I-5 corridor pricing, asphalt humps run $125 to $375 per linear foot installed and modular rubber humps run $165 to $375 per linear foot installed.

Current market reality
Per-foot pricing in 2026 sits roughly 15 to 20% above 2024 baselines, driven by hot-mix asphalt cost increases and tight traffic-control labor in Oregon. Multi-unit projects on the same street save 15 to 25% on per-foot cost because mobilization, traffic control, and pavement marking efficiencies compound. Per-foot is the right pricing unit when comparing across road widths; per-unit pricing assumes a fixed lane width and breaks down on wider streets.
Why does per-foot pricing make sense?
Two reasons:
- Lane width varies. A residential street with a 10-foot lane needs different material volume than an arterial with a 14-foot lane. Per-foot normalizes the comparison.
- Multi-lane streets need extension. A two-lane residential street (24 feet curb-to-curb) needs 24 linear feet of hump versus 12 linear feet for a one-way segment. Per-foot keeps the math straight when scaling.
The Federal Highway Administration's Traffic Calming ePrimer documents traffic-calming device pricing in per-foot terms specifically for this reason (FHWA ePrimer).
What does the per-foot price include?
A typical per-foot price covers material, labor, and signage allocated to that linear foot of lane. The breakdown for an asphalt 12-foot Watts profile in 2026:
| Per-Foot Component | Cost Range |
|---|---|
| Hot-mix asphalt material | $33 to $100 |
| Labor (crew + traffic control) | $75 to $265 |
| Pavement marking + signage | $17 to $50 |
| Mobilization (allocated) | $0 to $40 |
| Per linear foot total | $125 to $375 |
How does length (direction of travel) affect per-foot cost?
The 14-foot Seminole and sinusoidal profiles use 16% more asphalt than the 12-foot Watts but only roughly 5 to 8% more crew time. Per-foot pricing ends up similar across these three profiles. The 22-foot flat-top (speed table) is the outlier because it uses 85% more material, more careful screeding for the flat top, and more complex pavement marking.
| Profile | Length (Direction of Travel) | Per Linear Foot of Lane (Single Unit) |
|---|---|---|
| 12 ft Watts | 12 ft | $125 to $375 |
| 14 ft Seminole | 14 ft | $130 to $360 |
| 14 ft sinusoidal | 14 ft | $130 to $395 |
| 22 ft flat-top | 22 ft | $230 to $680 |
Multi-unit per-foot savings
A 4-hump project on a single residential street typically lands at $90 to $295 per linear foot for asphalt Watts profiles, versus $125 to $375 for a single-unit job. The 25% savings shows up in three line items:
- Material delivery is consolidated (one truck visit versus multiple)
- Traffic control runs continuously
- Mobilization spreads across all units

Comparison to alternative devices (per-foot)
For context, here is how speed humps compare to other traffic-calming devices on a per-linear-foot basis:
| Device | Per Linear Foot of Lane (Single Unit) |
|---|---|
| Asphalt speed hump (12 ft Watts) | $125 to $375 |
| Modular rubber speed hump (12 ft) | $165 to $375 |
| Speed cushion (modular rubber) | $400 to $1,200 |
| Speed table (22 ft asphalt) | $230 to $680 |
| Brick-inlay speed table | $750 to $2,500 |
| Raised crosswalk (asphalt + paint) | $250 to $750 |
How to use per-foot pricing in budget planning
Three steps:
- Measure lane width. Use a tape measure or a Google Earth ruler. Account for both directions if it is a two-way street.
- Multiply by per-foot range. Use the lower bound for multi-unit projects on standard sites; use the upper bound for single-unit jobs with prevailing-wage requirements or complex traffic control.
- Add a 10 to 20% contingency. Site-specific conditions (drainage, utility crossings, pavement condition) often push the final number above the simple multiplication.
For a 12-foot lane on a typical Oregon residential street, single-unit asphalt Watts profile budget would be 12 ft x $125 to $375 = $1,500 to $4,500 plus 15% contingency = $1,725 to $5,175. This matches the per-unit range in the speed hump cost guide.
Frequently asked questions
Why is per-foot pricing better than per-unit? Per-foot normalizes the comparison across lane widths. Per-unit pricing assumes a fixed lane width and undercounts wide-lane and multi-lane installs.
Does per-foot pricing include the warning sign? The signage cost spreads across the linear footage of the hump. The W17-1 sign is a fixed cost regardless of lane width; on wider lanes it allocates to fewer dollars per foot.
How does per-foot pricing change for two-way streets? A two-way street with two 12-foot lanes needs 24 linear feet of hump material. The per-foot rate does not change but the total cost scales with the doubled length.
Is rubber more expensive per foot than asphalt? At single-unit pricing, rubber is roughly 30% more per foot. At multi-unit pricing, rubber is roughly 35% more per foot. Asphalt's per-foot advantage compounds with its lifespan advantage.
Where does the per-foot price assume the device sits? On a paved surface (asphalt or concrete) at 0% to 2% cross-slope. Sloped or unpaved sites add cost not captured in per-foot pricing.
