Align your thresholds, instrumentation, and reporting with our PE-led team. We respond within one business day with tailored deployment options.
Freeways and interchanges represent the backbone of transportation infrastructure, facing relentless traffic loading, seismic activity, thermal expansion, and foundation settlement that can lead to safety concerns and costly closures. Heavy truck traffic, thermal cycling, and soil conditions create unique challenges for these critical assets. Seismic zones require special attention to liquefaction potential and bridge abutment stability. Our comprehensive monitoring systems use strain gauges on bridge elements, tilt sensors for foundation movement, and traffic load correlation analysis. We deploy nationwide across highway systems, providing data that supports maintenance prioritization, load rating updates, and emergency response planning. Our systems meet FHWA and state DOT requirements, delivering PE-stamped reports for compliance and funding applications. Real-time alerts help transportation authorities make informed decisions about lane closures and detour routing during structural events.
Popular Services in This Sector
Displacement Monitoring
Critical for tracking approach settlement and thermal expansion that affects ride quality and safety.
Strain Monitoring
Monitors stress in bridge girders and deck slabs from traffic loading and temperature effects.
Vibration Monitoring Services
Tracks traffic-induced vibrations that can accelerate fatigue in structural connections and bearings.
Inclinometer and Tilt Monitoring
Detects foundation tilt and abutment movement that could compromise bridge alignment.
Post-Event Rapid Assessment
Quick evaluation after earthquakes or floods to determine freeway safety for emergency response.
Compliance Reporting (NBIS/AASHTO/IBC)
Delivers FHWA-compliant documentation for bridge inspections and federal funding requirements.
Frequently Asked Questions
How do you monitor busy freeways without disrupting traffic?
We use wireless sensors and remote installation techniques that don't require lane closures. Nationwide deployment ensures minimal disruption to transportation systems.
What structural issues are most common in freeway interchanges?
Settlement, thermal cracking, and fatigue from heavy loads. Our monitoring nationwide helps prioritize maintenance before safety concerns arise.
How does monitoring support load rating updates?
Our strain data provides actual load response information for accurate bridge ratings. Systems nationwide support DOT load rating requirements.
What happens during extreme weather events?
Our robust systems maintain connectivity during storms and provide data for emergency response. Nationwide coverage ensures continuous monitoring of critical transportation infrastructure.
