Jersey Barrier Weight: 10ft, 12ft & 20ft Specs

A standard 10-foot F-shape jersey barrier weighs approximately 4,000 pounds (1,815 kilograms). A 12-foot section runs about 5,000 pounds. A 20-foot section runs about 8,000 pounds. The 32-inch height with 24-inch base width is the geometry that produces this weight at standard 4,000-PSI concrete density of about 145 pounds per cubic foot. Taller and heavier-rated variants weigh more — a 42-inch high-speed section adds about 1,200 pounds, and a 54-inch MASH TL-5 section adds about 2,400 pounds.

The weight is what makes a jersey barrier work. The redirective behavior of the F-shape profile depends on the barrier mass staying in place during impact, not being displaced. Lighter alternatives (plastic water-filled barriers, for example) get you channelization but not real redirective crash performance.

How Much Does a Standard 10-Foot Jersey Barrier Weigh?

The default 10-foot F-shape jersey barrier weights vary slightly by manufacturer and exact concrete mix density:

Manufacturer Spec	Weight Range
Oldcastle Infrastructure (10 ft, 32 in F-shape)	3,900 to 4,200 lb
Knife River (10 ft, 32 in F-shape)	3,800 to 4,100 lb
Concrete Industries (10 ft, 32 in F-shape)	4,000 to 4,400 lb
Bryan Concrete regional (10 ft, 32 in F-shape)	3,800 to 4,200 lb
Generic precast spec	~4,000 lb

The arithmetic: a 10-ft section at 32-in height with the F-shape profile contains approximately 27 cubic feet of concrete. At 145 pounds per cubic foot for standard 4,000-PSI mix, that produces 3,915 pounds plus rebar, plus connection hardware. Real weights cluster in the 3,800 to 4,400 pound range.

What Do Other Section Lengths Weigh?

Section length scales the weight roughly linearly because the cross-section is constant:

Section Length	Profile	Height	Approximate Weight
6 ft	F-shape	32 in	~2,400 lb
8 ft	F-shape	32 in	~3,200 lb
10 ft (standard)	F-shape	32 in	~4,000 lb
12 ft	F-shape	32 in	~4,800 to 5,200 lb
16 ft	F-shape	32 in	~6,400 lb
20 ft	F-shape	32 in	~8,000 lb
30 ft (uncommon)	F-shape	32 in	~12,000 lb

20-foot sections at 8,000 pounds approach the practical limit for over-the-road flatbed delivery (most flatbeds carry up to 4 sections at 8,000 pounds each plus crane access weight). 30-foot sections require permitted oversize loads.

What About Tall Variants and TL-5 Barriers?

Adding height increases section weight at the same length:

Configuration	Section Length	Height	Approximate Weight
Standard F-shape	10 ft	32 in	~4,000 lb
High-speed F-shape	10 ft	42 in	~5,200 lb
MASH TL-5 reinforced	10 ft	54 in	~6,400 lb
Single-slope (Texas T-22)	10 ft	32 in	~4,200 lb
Single-slope tall	10 ft	42 in	~5,400 lb

Single-slope profiles are slightly heavier than F-shape at the same height because the constant-slope geometry has more concrete cross-section. The trade-off is better post-crash repair characteristics on single-slope, which is why several state DOTs have moved to single-slope as their default.

Why Does the Weight Matter for Crash Performance?

Jersey barrier crash performance is partly mass-driven. When a vehicle strikes the barrier, momentum is transferred from the vehicle to the barrier system. A heavier barrier deflects less and stays in position better, which is what allows the F-shape profile to redirect the vehicle.

AASHTO MASH crash testing certifies the barrier as a complete system at its rated weight. Substituting a lighter section -- a plastic water-filled imitation, an under-spec concrete mix, a thinner cross-section -- changes the redirective behavior. This is why plastic water-filled barriers are not interchangeable with concrete jersey for crash-rated work, even though they share the F-shape silhouette.

What Crane and Rigging Do You Need?

Crane sizing for jersey barrier placement is dictated by section weight plus a 25 percent safety factor:

Industry Baseline Range

Section Weight	Recommended Crane Capacity	Lift Method
Up to 4,500 lb (10-ft F-shape)	30-ton capacity at working radius	2-point spreader bar to cast-in pickup eyes
4,500 to 6,000 lb (12-ft or 42-in F-shape)	35- to 40-ton at working radius	2-point spreader bar
6,000 to 9,000 lb (20-ft or 54-in F-shape)	50-ton at working radius	2-point spreader bar with engineered rigging
Forklift placement (level ground only)	8,000 to 10,000 lb forklift capacity	Fork-pocket sections only, level firm subbase

These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.

Current Market Reality

Crane and operator rates have moved up roughly 18 percent across the I-5 corridor since 2024. A 30-ton crane with operator runs $1,800 to $2,800 per 8-hour shift in 2026, and a 50-ton crane runs $2,800 to $4,200. Rigging gear (spreader bars, slings, shackles) is typically included in the crane day rate or charged at $150 to $300 per day for project-specific rigging. The most reliable cost-savings move is matching crane size to the heaviest section on the project rather than oversizing.

Are There Lighter Alternatives?

Plastic water-filled barriers (Yodock, Triton, OBO) weigh 80 to 150 pounds empty and 1,000 to 1,800 pounds when filled with water. They mimic the F-shape silhouette but are not crash-rated. Manufacturer datasheets restrict redirective performance to impact speeds below 35 miles per hour. They serve channelization at events, construction-zone delineation in low-speed work zones, and pedestrian-flow control -- not real crash containment.

For perimeter work that needs MASH TL-3 redirective performance, concrete is the only answer. The weight is a feature, not a bug.

How Does Weight Affect Delivery?

Over-the-road flatbed deliveries are limited by gross vehicle weight regulations. For standard concrete jersey at 4,000 pounds per 10-ft section:

Truck Configuration	Sections per Load	Total Cargo Weight
Standard flatbed	8 to 10	32,000 to 40,000 lb
Tilt-deck flatbed (for 20-ft sections)	4 to 5	32,000 to 40,000 lb
Step-deck flatbed (low clearance)	8 to 9	32,000 to 36,000 lb

Delivery cost scales with truck count, not section count, so loading the truck to its weight limit is the cost-efficient call when project timing allows.
