Colorado's mountain highways traverse some of North America's most active rockfall zones. I-70 through Glenwood Canyon, the Million Dollar Highway on US-550, and US-6 through Clear Creek Canyon demand year-round rockfall protection that can withstand 10,000+ lb impact energies. GeoStabilization International designs and installs attenuator barriers, high-capacity rock bolts, draped TECCO® mesh systems, and performs precision scaling along Colorado's highest-priority corridors.
Our rope access Rockfall Remediation Technicians (RRTs) and SPIDER excavators reach vertical rock faces that conventional contractors cannot access—eliminating the need for expensive access road construction. CDOT trusts GSI with their most critical rockfall corridors because we own the engineering, the equipment, and the performance warranty under one design/build contract.
Colorado's mountain highways traverse geologic formations that produce some of North America's highest-energy rockfall events. Glenwood Canyon on I-70 experiences rockfall from 2,000-foot cliff faces, generating impact energies exceeding 10,000 kJ. The Million Dollar Highway (US-550) between Ouray and Silverton, Clear Creek Canyon on US-6, and McClure Pass on CO-133 all require engineered rockfall protection systems calibrated to Colorado's unique geologic conditions.
GeoStabilization International has served as CDOT's trusted rockfall mitigation partner across the state's most critical corridors. Our systems include high-energy attenuator barriers rated for 5,000+ kJ impacts, pattern rock bolting to stabilize massive detached blocks, draped TECCO® mesh systems that contain rockfall against the slope face, and precision mechanical scaling using the proprietary SuperScaler™ tool.
The I-70 Glenwood Canyon corridor demands rockfall protection engineered for extreme conditions—narrow canyon geometry, active rail corridor below, and rock faces exceeding 1,500 vertical feet. Our rope access teams and specialized drilling rigs work directly on these vertical faces, installing protection systems without closing the highway. This capability—combining engineering depth with limited-access field execution—is what separates GeoStabilization International from every other rockfall contractor bidding Colorado work.
When a rockfall event closes I-70 through Glenwood Canyon or blocks the Million Dollar Highway, every hour of closure costs the state economy millions. GeoStabilization International maintains 24/7 emergency response capability with pre-staged equipment and Colorado-based crews ready to mobilize within hours. Our emergency teams assess, design, and execute rockfall stabilization at a pace no other contractor can match—because we own the engineering, the specialized equipment, and the field crews under one roof.
GeoStabilization International has protected Colorado's most critical corridors for over two decades. From Glenwood Canyon to US-550, our rockfall engineers deliver CDOT-trusted solutions. Call today.
