Among the debris closing the road were two large boulders weighing an estimated 2.3 million pounds and 8.5 million pounds, respectively. The Colorado Department of Transportation (CDOT) was first on the scene to evaluate the damage and determine a course of action. Because the origin of the rockfall was 1,800 slope feet above the roadway, CDOT deployed a drone from <a href=\"https:\/\/mapware.com\/\" target=\"_blank\" rel=\"noopener\">Aerial Applications Colorado<\/a> to gather information for the mitigation efforts.<\/p>\n<p>The event impacted about 150-200 linear feet of roadway, damaged power lines and fencing, and caused minor damage to a vehicle. The story was broadcast <a href=\"https:\/\/www.cbsnews.com\/news\/massive-boulder-closes-colorado-highway-indefinitely\/\" target=\"_blank\" rel=\"noopener\">nationally<\/a> and <a href=\"https:\/\/www.bbc.com\/news\/world-us-canada-48415293\">internationally<\/a> on various news outlets.<\/p>\n<p>CDOT notified GeoStabilization International (GSI) of the event shortly after it occurred, and the GSI team started mobilizing to the site. Working directly with CDOT\u2019s Geohazards Program representatives and engineers from <a href=\"https:\/\/www.yeh-eng.com\/\" target=\"_blank\" rel=\"noopener\">Yeh and Associates<\/a>, the team assessed the situation and developed a mitigation plan that included rock scaling and boulder downsizing in order to safely reopen the highway. By the following evening, GSI\u2019s Rockfall Remediation Technicians (ferried to the upper slopes by <a href=\"https:\/\/www.mbrhelicopters.com\/intro\" target=\"_blank\" rel=\"noopener\">Mountain Blade Runner Helicopter<\/a>) had completed safety scaling from the source location 1,000 vertical feet above the highway down to the roadway surface along the \u201crunout path\u201d the boulders had created as they rolled down the slope. The following day, GSI and Bedroc Blasting, Inc. from Cortez, Colorado downsized the smaller of the two boulders using controlled blasting. The larger of the two boulders will remain intact at the side of the road. Williams Construction, Inc. mobilized excavators, a hydraulic hammer, and a large loader to further downsize and remove the rock fragments. CDOT Region 5 Maintenance forces played a critical role in the overall operation and were responsible for creating temporary lanes to reopen traffic to Highway 145 on Memorial Day (only three days after the rockfall occurred).<\/p>\n<p>When this event occurred on Friday, initial indications were that the road would be closed \u201cindefinitely.\u201d GSI is proud to have been a part of the CDOT-led team that restored mobility to the corridor only three days after the massive rockfall event occurred.<\/p>\n<img decoding=\"async\" class=\"size-full wp-image-3158 aligncenter\" src=\"https:\/\/www.geostabilization.com\/ca\/wp-content\/uploads\/sites\/5\/2023\/11\/CDOT-GSI-Rockslide-HWY-145-1.jpg\" alt=\"CDOT GSI Rockslide HWY 145\" width=\"747\" height=\"560\" srcset=\"https:\/\/www.geostabilization.com\/ca\/wp-content\/uploads\/sites\/5\/2023\/11\/CDOT-GSI-Rockslide-HWY-145-1.jpg 747w, https:\/\/www.geostabilization.com\/ca\/wp-content\/uploads\/sites\/5\/2023\/11\/CDOT-GSI-Rockslide-HWY-145-1-300x225.jpg 300w\" sizes=\"(max-width: 747px) 100vw, 747px\" \/>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n<!-- End Block: acf\/wysiwyg -->","protected":false},"excerpt":{"rendered":"<p>GeoStabilization International\u00ae assists the Colorado Department of Transportation to restore roadway mobility after two house-sized boulders destroy HWY 145 near Dolores, Colorado over Memorial Day weekend.<\/p>\n","protected":false},"author":1,"featured_media":3152,"parent":0,"menu_order":0,"template":"","tags":[],"news-category":[],"class_list":["post-3151","news","type-news","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
