Its opening will provide another access point for residents and businesses in the southern part of town, where development has expanded in recent years.</p><p>The project is intended to serve the established Crystal Valley neighborhood as well as the developing Dawson Trails community. Additional commercial projects, including a Costco, a King Soopers grocery store and an HCA HealthONE facility, have also received approval for the area.</p><h2>A new connection for a growing community</h2><p>The interchange comes as Douglas County continues to experience population growth. The county’s population increased by nearly 24% over the past decade, creating additional demand for transportation connections and services.</p><p>For years, many Crystal Valley residents have relied on the Plum Creek interchange and nearby frontage road to reach <a href="https://rollingout.com/2026/09/26/colorado-crash-temporarily-closes-i-25/">I-25</a>. The additional access point is expected to make those trips more convenient while supporting the area’s expanding residential and commercial developments.</p><p>Local business owners have also watched the neighborhood change as new homes and retail destinations have arrived.</p><p>The opening of the interchange is expected to make the shopping center easier to reach, particularly for people traveling from nearby communities.</p><h2>Costco and other developments add to the area’s growth</h2><p>Dawson Trails is among the developments expected to bring additional residents to the western side of the highway. Its first homes are part of a broader expansion that is also attracting major retailers and other services.</p><p><a href="https://rollingout.com/2026/11/13/costco-kirkland-whipped-cream-recall/">Costco</a> is scheduled to open early next year, giving Castle Rock residents another option for shopping closer to home. Some residents currently make longer drives to reach grocery stores and warehouse retailers.</p><p>The trip to a grocery store can take between 15 and 20 minutes. Reaching Costco currently requires a drive of about 45 minutes, depending on traffic.</p><p>The new store is expected to reduce that travel burden for residents once it opens. Business owners in Crystal Valley Commons also anticipate that the combination of new homes, retail development and improved highway access could bring more customers to the neighborhood.</p><h2>Project completed ahead of schedule</h2><p>Planning for the interchange dates back several decades, with the connection originally proposed in the 1980s. Construction began in recent years, and the project is now reaching its final opening milestone.</p><p>The town of Castle Rock identified the interchange as a major transportation priority. The project was completed eight months ahead of schedule and within its budget, according to local officials.</p><p>The total cost has been listed at approximately $144.7 million, although the project has also been described in rounded terms as a $150 million investment.</p><p>The work has been completed in stages. Northbound entrance and exit ramps opened earlier this year, giving drivers an initial connection to I-25. The town reported that the first phase reduced traffic at the Plum Creek interchange by 50%.</p><p>Residents have already noticed changes to their commutes. Muller said the northbound ramps have shortened some school trips by several minutes. She expects the full opening to make travel easier for her family, including the drive to her son’s school in Larkspur.</p><p>The remaining southbound entrance and exit ramps are scheduled to open this weekend. Once they are available, drivers will have access to the interchange in both directions.</p><h2>How the project was funded</h2><p>The interchange was supported through a combination of public funding, grants and developer contributions.</p><p>Developer contributions accounted for $53.6 million of the project funding. Douglas County provided $24 million for the interchange, along with another $11 million for the West Frontage Road, which is expected to be renamed Dawson Trails Boulevard.</p><p>Other funding sources included an $8.9 million grant from the Denver Regional Council of Governments and a $5.4 million BUILD grant from the U.S. Department of Transportation.</p><p>The town also contributed $1.7 million in electric credits, while BNSF Railway provided $900,000.</p><p>With the southbound ramps set to open, the interchange will provide a new connection for residents, commuters and businesses as Castle Rock continues to develop. The completed project is expected to ease reliance on the Plum Creek exit and improve access to the growing communities on both sides of <a href="https://www.codot.gov/programs/expresslanes/i-25-central-express-lanes">I-25.</a></p><div style="position:relative;width:100%; height:0; padding-bottom: 56.25%;"><iframe src="https://www.youtube.com/embed/XKJ1-6sSHyI?si=bJhPusERY037Pc_1" allowfullscreen frameborder="0" style="width:100%; height:100%;top:0; left:0; position:absolute"></iframe></div></div></body>
