Drainage improvement project at Niwot Road and Walker Avenue requires lane closure on Walker with detours for northbound traffic
A drainage improvement project will start at the intersection of Niwot Road and Walker Avenue on Monday, Dec. 13. To safely facilitate the project, traffic on Walker Avenue will be limited to southbound only, which means traffic will only be able to enter onto Walker from Niwot Road and not exit. A temporary traffic signal will be installed at Paiute Avenue during construction so residents and school staff and visitors can safely exit the area. The multi-use path and crosswalk at Niwot Road and Walker Avenue will remain open during construction. View a map of the traffic control plan for more details on detour routes. The project is expected to take seven weeks to complete, weather permitting.
Magnolia Road bridge rehabilitation project underway
The bridge just south of CO 119/Boulder Canyon Drive on Magnolia Road over Boulder Creek is currently being rehabilitated. In addition to strengthening the bridge, new drainage structures will be installed in the area and the bridge will be resurfaced. Work will take place from 8 a.m. to 5 p.m., Monday through Friday. During working hours, Magnolia Road will be reduced to one lane in the area. Flaggers will be used to direct traffic traffic safely through the work zone, so expect delays. Work is expected to last through January. Crews may need to return in the spring, when temperatures are more favorable, to complete the repaving portion of the project.
