For India's Bridges & Highways

Every span,
continuously measured.

MoRTH-mandated, real-time Structural Health Monitoring for the 3,647 major bridges on India's national and state highways - without closing a single lane.

Context

A decade of bridges built.
A decade of bridges ageing.

Nearly 30% of India's national highway bridges are 30+ years old. Post-pandemic freight loading is at an all-time high, and MoRTH has moved SHMS from "optional" to "mandatory" on every major span.

Smallest deck or pier deflection SuryaGbSAR can resolve
How It Applies

From pier base to deck soffit.

SuryaGbSAR mounts on an adjoining abutment, pillar or roadside station and scans the entire structure at full bandwidth - day and night, without affecting traffic.

🏗️

Deck deflection under load

Resolve mid-span deflection in real time against live traffic - validate WIM data and flag outlier truck events that structurally matter.

🧱

Pier & abutment settlement

Continuous sub-millimeter tracking of pier settlement and abutment rotation - particularly post-monsoon and during scour-prone seasons.

🎯

Cable & stay tension

Frequency-domain analysis from radar amplitude reveals cable-stay tension drift and localised corrosion-driven stiffness loss.

🌊

Scour & flood response

Rapid post-flood scans quantify residual deformation and inform go/no-go reopening decisions.

🚛

Load-posting validation

Verify whether reduced load postings are actually preventing fatigue on critical bridges.

MoRTH compliance reports

Auto-generated monthly Health Index reports in MoRTH Circular-3/2021 format.

Customers

Designed for NHAI.
Priced for State PWDs.

A single SuryaGbSAR station can monitor multiple adjacent bridges on a corridor, bringing the unit economics into range for even state-highway bridges that legacy SHMS has never touched.

NATIONAL

NHAI, MoRTH, NHIDCL, BRO

Corridor-level rollouts across golden quadrilateral, Bharatmala, and border roads.

STATE & URBAN

State PWDs, MMRDA, DMRC, BMRCL

Urban flyovers and metro viaducts where closures cost millions per day.

Deployment

Traffic stays open.
Measurement stays on.

Day 1 · Walkover

Structural engineer + radar tech walkover. Mount-station siting. No lane closures.

Day 2-4 · Mount

Trailer or mast installation at a roadside line-of-sight location. Power & comms.

Day 5 · Baseline

24h baseline capture under normal traffic. Frequency modes extracted.

Day 6 · Live

Continuous scans. Alerts integrated into NHAI control room or city command centre.
