Highway lighting has to solve a specific problem: illuminating a junction, toll plaza, or interchange for driver visibility and safety without creating glare that does the opposite. Here's what a highway-grade high mast project typically involves.
Interchanges, toll plazas, major junctions, and rest areas are the typical application — locations where a cluster of tall poles (25–30m) can cover a wide area with fewer poles and less visual clutter than standard streetlights, and without poles placed inside the driver's direct sightline.
Highway lighting projects under NHAI or state PWD contracts require poles and foundations designed to IS 875 wind load and IS 2713 standards, along with the structural drawings and test certificates needed for government inspection and handover.
Poor optic selection on highway poles creates glare for drivers rather than improving visibility — luminaire beam angle and mounting height are calculated specifically to light the carriageway without shining directly into oncoming traffic.
Poles on operational highways need lowering-ring mechanisms so maintenance doesn't require lane closures or crane mobilization on a live road — a practical consideration that's easy to overlook at the design stage but expensive to retrofit later.
Do you handle lighting for NHAI-awarded highway contracts?
Yes, we've executed high mast lighting for expressway and highway projects including multi-pole NH stretches, designed and documented to NHAI-compliant standards.
What pole height is standard for a highway interchange?
25–30m is typical for interchanges and major junctions, though the exact height and spacing depend on the carriageway width and required lux level for that specific junction.
