Colorado officials hope to start widening a congested stretch of Interstate 25 between Monument and Castle Rock in 2019. The five-year project can begin in two years if the state can find up to $400 million for construction. CDOT has devoted $15 million in cost savings from a C-470 Express Lanes project to speed up planning for the I-25 project. The 17-mile stretch of highway has two lanes in each direction.
