News | 1.05 million bridges are undergoing “regular check-ups,” with SPEPC prescribing a lightweight monitoring “prescription”
1.05 million bridges are aging en masse, yet monitoring coverage for 880,000 small and medium-sized bridges remains below 1%. With the 2030 policy of full coverage for national and provincial highways looming, implementation is stalled due to high costs, significant damage, and difficulties in practical deployment. SPEPC Visual Intelligent Deformation Monitor—non-contact, sub-millimeter precision, and non-invasive to bridge structures—offers a lightweight monitoring solution for millions of bridges.
First, let’s look at a set of figures worth noting:
1.05 million seats
Total number of highway bridges nationwide
84%
The proportion of small and medium-span bridges
80%
Proportion of bridges that have been in service for over 20 years and have entered a period of high disease incidence.
0.57%
Automation monitoring coverage rate for small and medium-sized bridges
30 billion+
During the 15th Five-Year Plan period, there is a market gap in the monitoring of small and medium-sized bridges.
Millions of bridges are aging en masse, yet monitoring has failed to keep pace.
01 The bridge monitoring industry has undergone a major shift.
The country has hit the accelerator.
In 2024, Implementation Plan on Further Promoting Structural Monitoring of Highway Bridges and Tunnels Specific requirements:
By 2030, full coverage of bridge monitoring will be achieved for expressways and ordinary national highways.
The monitoring rate for key bridges on ordinary provincial roads exceeds 60%.
The industry is undergoing a fundamental transformation:
From “Specialized Monitoring for Extra-Large and Major Bridges” Turn Pan-Network Universal Monitoring 。
The 14th Five-Year Plan
Monitoring focuses on 1,115 long and large bridges.
“The Fifteenth Five-Year Plan”
The construction focus extends to approximately 300,000 to 500,000 small- and medium-span bridges.
Based on an estimated base configuration of RMB 100,000 per unit, this would be a… 30 to 50 billion yuan The rigid-demand market.
02 Traditional approaches no longer work.
In the past, intelligent bridge monitoring was severely skewed, resulting in an imbalanced landscape where large bridges were heavily equipped while smaller bridges were left largely unmonitored.
Small and medium-sized bridge monitoring has long faced a triple dilemma:
· The cost is too high.
Traditional wired monitoring systems start at a cost of one million yuan per unit, far exceeding the budgets allocated for the maintenance of small and medium-sized bridges.
<
· The damage is too great.
Construction requires drilling and grooving, as well as the installation of concealed cables, which can inflict irreversible secondary structural damage on aging bridges.
<
· Coverage is too difficult.
880,000 small and medium-sized bridges are scattered throughout county- and township-level road networks, and conventional solutions are entirely unsuitable for large-scale deployment.
<
Meanwhile, the standardization of monitoring has also been further enhanced:

2026 Edition of the “Technical Condition Assessment Standard for Highway Bridges” (Draft for Approval) It has revolutionized the evaluation logic—shifting from traditional holistic scoring to precise, component-level assessment.
Even minute deformations and microcracks in a single component must be included in the risk assessment.
Quarterly manual inspections alone can no longer meet the requirements of the new standards.
03 SPEPC Solution
Facing Low cost, protective structure, continuous monitoring SPEPC’s triple wish, fulfilled in one go by Spepc Technology.
Visual Intelligence Deformation Monitor
Based on machine vision and AI algorithms, by performing high-precision positioning of targets deployed at monitoring locations, it is possible to measure the two-dimensional displacement and deformation of the target under test. Non-contact real-time measurement 。
Non-contact, no damage to the bridge.
No need to drill holes, cut grooves, or embed cables in the bridge structure—ideal for aging bridges. Zero damage 。
Install and use right away , deployed and launched on the same day.
High precision, accurate vision
Equipped with a high-resolution image sensor and sub-pixel positioning algorithms, it offers a maximum detection range of 400 meters with an accuracy of Submillimeter-level 。
A single device can simultaneously monitor multiple targets. , supporting large‑area, multi‑cross‑section, long‑distance, multi‑point monitoring.
Main girder settlement, bearing displacement, bridge tower inclination, and pier foundation offset—caused by repeated traffic loading and diurnal temperature variations. Millimeter-scale deformation , all can be accurately captured.
All-weather, reliable
Built-in constant-temperature control system, with temperature control accuracy reaching ±0.2℃ , effectively avoiding measurement errors caused by diurnal and seasonal temperature variations.
IP65 High protection rating, unafraid of complex outdoor weather conditions.
It provides early warnings and responds quickly.
Real-time intelligent data analysis; when displacement anomalies are detected, it automatically triggers web pop-up alerts and SMS notifications, and can be linked to on-site audio‑visual alarms.
From data anomaly detection to alert delivery, the entire process Minute-level response 。
04 Mature Solution
The technological prowess of the visual‑intelligence deformation monitoring instrument has been thoroughly validated across numerous transportation and structural safety monitoring applications.
