Castle Rock is one of the fastest-growing towns in Colorado. This growth brings many positive changes to our community but also has led to some traffic safety and operational issues as this growth outpaces funding for transportation improvements. In 2017, the Castle Rock Transportation Master Plan identified the need for improvements at the Four Corners intersection, located approximately two miles east of Downtown. This intersection of Founders Parkway, Fifth Street, State Highway 86, and Ridge Road currently serves more than 30,000 vehicles per day – a number that is expected to increase to more than 48,000 vehicles per day by 2040. This intersection also has a high crash rate and lacks connections/safe accommodations for bicyclists and pedestrians.
To address these safety and operational issues, the Town plans to improve the intersection with a solution that will last well into the future. The Town successfully secured regional funds through the Denver Regional Council of Governments to complete design and construction of these improvements. Design efforts began in late 2020, and the project is expected to begin construction in 2022.
