Boulder completes $25M waterline project
BOULDER — South 63rd Street in Boulder has been reopened to all travel, marking a milestone toward completion of a $25 million waterline replacement between Colorado Highway 119 and Boulder Creek, the city announced Friday.
In what a news release described as “one of the largest water infrastructure investments in the city’s recent history,” the project replaced and upgraded nearly two miles of Boulder’s water system with large-diameter pipes that help move drinking water throughout the city.
After a successful testing phase, the new pipes are fully operational, providing water to Gunbarrel residents and businesses as well as customers elsewhere across the city.
While 63rd Street has been temporarily patched with new asphalt, travelers will notice that the city has not yet finalized resurfacing of the pavement. Resurfacing will be finished in late spring, pending warmer morning temperatures, according to utilities officials, which will give the road a finished appearance and provide a smooth driving experience.
Work will take place from Twin Lakes Road to just north of Valmont Road at Boulder Creek. Construction will require closing the intersection of 63rd Street and Jay Road for up to two days in late spring. All other construction will not require full closures of the street, intersections, or multi-use paths but will involve short-duration traffic controls.
Impacts will be posted on the city’s Cone Zones page.
“We’re pleased to celebrate not just the reopening of a road and multi-use path, but the delivery of a lasting investment that will serve our community’s quality of life for decades to come,” Chris Douglass, utilities engineering senior manager, said in a prepared statement. “With projects of this size, particularly with adjacent construction taking place, we know the work had a major impact on our neighbors and businesses in Gunbarrel and are immensely grateful for their patience.”
