It\u2019s universally recognized that this project is needed.\u201d<\/p>\n<p>The alternative? A 449-mile detour<\/p>\n<p>Highway 101 is the <a class=\"link\" href=\"https:\/\/www.latimes.com\/00000199-0d0d-d52a-a9fb-9f2dc3a00000-123\" data-autoplayable-video=\"true\" rel=\"nofollow noopener\" target=\"_blank\">only viable route<\/a> linking Crescent City, a <a class=\"link\" href=\"https:\/\/www.latimes.com\/california\/story\/2025-08-05\/tsunami-caused-1-million-damage-crescent-city-harbor\" rel=\"nofollow noopener\" target=\"_blank\">tsunami-prone town<\/a> of 6,000 people, with neighboring Humboldt County and the rest of the state.<\/p>\n<p>When Last Chance Grade is closed, the only alternative route between Crescent City and the little town of Klamath 20 miles south \u2014 aside from steep, unpaved logging roads \u2014 is a circuitous 449-mile, eight-hour detour through Redding and southern Oregon. <\/p>\n<p>            <img class=\"image\" alt=\"A motorcycle cruises Highway 101 over a retaining wall propping up Last Chance Grade south of Crescent City.\"   width=\"1200\" height=\"732\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2025\/10\/1761277214_92_\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>A motorcycle cruises Highway 101 over a retaining wall propping up Last Chance Grade south of Crescent City. <\/p>\n<p>(Mike Zacchino \/ For The Times)<\/p>\n<p>Del Norte County Supervisor Valerie Starkey told me last year that many Klamath children attend school in Crescent City and rely on the campus\u2019 free meals. When rocks and mud buried Last Chance Grade in early 2021, she said, school employees hauled lunches to the base of the landslide and handed them to Caltrans workers to take to kids on the other side.<\/p>\n<p>Klamath residents also travel to the small hospital in Crescent City. And Crescent City residents use the road to access specialized medical care, including chemotherapy, more than 80 miles south in Humboldt County.<\/p>\n<p>Engineers always knew the cliffs were unstable<\/p>\n<p>Last Chance Grade was first built as a wagon trail through the dense redwood forest in 1894. It was constructed in its current alignment in the 1930s, but before the work began, an engineer noted that it would be expensive to maintain because of constant land movement.<\/p>\n<p>During construction, \u201cmany slipouts and slides occurred, delaying construction,\u201d according to a <a class=\"link\" href=\"https:\/\/lastchancegrade.com\/files\/managed\/Document\/51\/lcg_efs_final.pdf\" target=\"_blank\" rel=\"nofollow noopener\">2015 project feasibility study<\/a> commissioned by Caltrans.<\/p>\n<p>The warped, cracked roadway is perched atop four active landslides. It is so unstable that it was reduced to one-way traffic for nine years straight, reopening in October 2023 \u2014 only to be repeatedly reduced since then. <\/p>\n<p>Portions of the highway have shifted 40 feet horizontally and 30 feet vertically since the 1930s, according to Matteoli. The movement has accelerated over the last decade, with some sections now slipping several feet a year toward the Pacific.<\/p>\n<p>Crews have built more than two dozen retaining walls to prop up the roadway. But those, too, have shifted, cracked and broken. In 1972, Last Chance Grade crumbled in the predawn darkness, and a married couple died after their Ford sedan went over the cliff.<\/p>\n<p>The tunnel would run through an ancient Redwood forest<\/p>\n<p>The <a class=\"link\" href=\"https:\/\/lastchancegrade.com\/app_pages\/view\/835\" target=\"_blank\" rel=\"nofollow noopener\">proposed underground tunnel<\/a>, east of the existing highway, would bypass the areas with the most intense geologic instability, according to the environmental impact report. <\/p>\n<p>At 6,000 feet, it would become the longest highway tunnel in California, far surpassing the 4,233-foot Wawona Tunnel in Yosemite National Park.<\/p>\n<p>            <img class=\"image\" alt=\"Artist rendering of a proposed tunnel \"   width=\"1200\" height=\"806\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2025\/10\/1761277214_484_\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>An artist\u2019s rendering shows the proposed tunnel that would bypass a hazardous section of Highway 101 known as Last Chance Grade south of Crescent City.<\/p>\n<p>(California Department of Transportation)<\/p>\n<p>The highway runs through Redwood National and State Parks, a designated UNESCO World Heritage Site. Tunnel construction would result in the loss of 16 old-growth redwood trees wider than 4 feet, in addition to other trees, according to the environmental impact report.<\/p>\n<p>The timeline<\/p>\n<p>Caltrans is expected to ask the California Transportation Commission for $225 million later this summer to fund the tunnel\u2019s design phase, which involves international experts in tunnel design and construction in seismically active zones, Matteoli said.<\/p>\n<p>Matteoli said the project is on track to begin construction by about 2031, with the tunnel potentially opening by 2038.<\/p>\n<p>Locals have told me they\u2019re not thrilled about the long timeline.
