Work continues on the Front Avenue Northwest Improvement Project in downtown Castle Rock, with work being wrapped up on the installation of a new water main and service connections. The switchover to the new main is expected to take place on Wednesday of next week. Over the next week, the project contractor is planning to start removing the street surface along Front Avenue, and will also continue with construction of retaining walls. Saturday morning, participants in the “I Topped the Rock” fun run are expected to go through the project area. Traffic closures and access measures remain in place; contact Castle Rock Public Works at 274-7478 if you have questions.
