Landslide Monitoring I-40, Asheville, USA

Asheville, North Carolina, USA
Project duration:  Started May 2025, and currently still active

After Hurricane Helene caused major damage to Interstate I-40 and forced a months-long closure, the highway partially reopened in March 2025. Continuous monitoring is essential to ensure slope stability. A network of precision sensors provides early detection of movement, enabling timely safety interventions.

 

Basetime GNSS monitoring device tracking landslide movement on the I-40 slope in Asheville, North Carolina.
Direct insight into potential ground movement, enabling timely road closures and significantly reducing liability risks.

Project Purpose

The objective is to monitor the I-40 slope in real time and detect any potential ground movement. By combining different sensor technologies, various failure mechanisms can be identified, allowing for faster and more reliable risk assessment.

Implemented Solution

A comprehensive monitoring system was deployed using Locator One units and multiple tilt sensors. The combination makes it possible to measure both large-scale displacements and smaller rotational or rolling movements. With high measurement frequency and three reference stations, the slope’s stability can be assessed continuously and accurately.

Key Results
