• Sugar Loaf Street. Due to an unsafe and crowded work zone, Sugarloaf Road between Colorado 119 and Betasso Road is to be closed for the next four weeks at the following times: Monday through Friday from 9:30 a.m. to 12:00 p.m. and from 1:00 p.m. to 3:30 p.m. Sugarloaf Road will remain open in a single lane configuration through the work zone at all other times. Boulder County is currently working on the final 2013 flood restoration project on Sugarloaf Road. The project includes the construction of five retaining walls, drainage improvements and the rebuilding of approximately 2,000 feet of roadway just above Colo. 119 and will include a 4-foot shoulder in the uphill lane. In addition, CO 119/Boulder Canyon Drive will be reduced to one lane during working hours (8:00 a.m. to 4:30 p.m., Monday through Friday). The project is expected to last until October, weather permitting.

• Annual Paving Works: Work will occur in the following order: 79th Street between Colorado 52 and Niwot Road; Monarch Road between 79th Street and the Diagonal Highway (Colo. 119); 73rd Street between Diagonal Highway and Niwot Road; Niwot Road between Diagonal Highway and 73rd Street; 63rd Street between Jay Road and Boulder town limits; Second Avenue in Niwot; and Valmont Road between Boulder Creek and 61st Street. Each section will take about a week to build, with the exception of Second Avenue in Niwot, which should take two to three days. The paving work involves milling the old road surface and laying a layer of new asphalt. Motorists and cyclists must expect one-lane closures in construction sites. Flags are used to guide travelers safely through construction work; Expect delays and be careful when passing through the zone. The work will take place Monday to Thursday from 6:30 a.m. to 4:30 p.m. and is expected to continue through August, weather permitting.

• Olde Stage Road Project: A major redevelopment project has begun on the Olde Stage Road between the Lee Hill and Lefthand Canyon ramps. In addition to refurbishing the entire Olde Stage Road, work will include widening the southern portion of the road for a 1.2m hard shoulder to be installed in the uphill lane to provide more space for cyclists, pedestrians, emergency services and disabled vehicles . Drainage improvements will also be installed. During working hours, the road will be reduced to one lane in several sections, which will result in travel delays of up to 15 minutes. Old asphalt is milled, so the speed is reduced on uneven ground. Cyclists may consider avoiding Olde Stage Road during construction. Driveways may be inaccessible for up to 30 minutes during paving as the asphalt must cool before motor vehicles can safely cross it. The crews will coordinate with the homeowners throughout the project. This is the final phase of a major Olde Stage Road reconstruction project that included the creation of two large retaining walls and the replacement of a culvert at Six Mile Creek with a larger and stronger structure capable of accommodating larger currents during potential flood events. The work will take place on weekdays between 8:00 a.m. and 4:30 p.m. The project is expected to last until October.
