Highway Post and Rail Fencing






Highway Post & Rail Fencing
Highway post and rail fencing, often referred to as Highways Specification fencing or motorway rails, is the definitive choice for demanding roadside environments. Engineered for strength, this system combines substantial vertical posts with heavy-duty horizontal rails to create a formidable physical barrier that stands the test of time.
Why Choose Highways Specification?
- Uncompromising Durability: Made from heavy-duty incised timber, this timber post and rail fencing is designed to resist decay and withstand harsh roadside pollutants, offering a long service life where reliability is paramount.
- Clear Demarcation: The open post and rail fence design ensures essential driver visibility while providing a secure border between public highways, private land, and livestock.
- Versatile Application: While primarily used as motorway rail fencing, its robust nature makes it an excellent upgrade for commercial properties or agricultural sites requiring a boundary tougher than a standard post and rail fence.
- Adaptable Installation: Whether you are working on long straight runs, undulating terrain, or curved road edges, this Highway rail system adapts easily to ground conditions using either driven or dig-in posts.
Available in 3 or 4-rail configurations, Highway Post and Rail offers a cost-effective, natural, and easily repairable alternative to steel or concrete, blending professional compliance with rural aesthetics.

Key Applications of Highway Rail Fencing
Our Highway rail timber systems are versatile enough to handle more than just the hard shoulder. Common applications include:
- Roadside Boundaries: Used as a high-performance Highway rail to separate high-speed traffic from surrounding land.
- Agricultural & Livestock: A robust timber post and rail fence solution for containing cattle or horses in large estates and farms.
- Commercial Perimeters: Ideal for business parks or industrial sites that require a professional, natural-looking boundary that is stronger than domestic fencing.
- Public Rights of Way: Providing clear, safe borders for footpaths and bridleways running adjacent to roads.
- Embankments & Slopes: The modular nature of highway post and rail makes it perfect for following the natural contours of hilly or uneven terrain.
