A month-long construction project to reline sewer pipes under Santa Fe Drive in Littleton is starting on Tuesday. Crews will be relining underground sanitary sewer lines to help prevent future problems. It's part of a larger project to replace more than five miles of the main sewer line that connects Littleton neighborhoods to the South Platte Renew treatment plant. https://www.9news.com/article/traffic/construction-santa-fe-ave-littleton/73-dd5fa081-d7c9-491b-8ff6-f268fa516c7a More local videos here: https://youtube.com/@9news Subscribe to NEXT: https://youtube.com/@Nexton9NEWS Stay connected: 9NEWS Website: http://www.9news.com/ Facebook: https://www.facebook.com/ilike9news Twitter: https://twitter.com/9NEWS Instagram: https://www.instagram.com/9newsdenver/ Download the 9NEWS App: https://www.9news.com/appredirect/ Sign up for the 9NEWSLETTER: https://www.9news.com/email 9NEWS (KUSA) is located in Denver, Colorado.
