Boulder County
—Sugarloaf Road: Boulder County started the last of the 2013 flood recovery-related projects on Sugarloaf. The project involves the construction of five retaining walls, drainage improvements and reconstruction of about 2,000 feet of roadway just up from Colo. 119 and includes a four-foot shoulder in the uphill lane. Temporary traffic signals were installed on Sugarloaf because the road is reduced to one lane in the construction zone. In addition, Colo. 119 and Boulder Canyon Drive is reduced to one lane during working hours from 8 a.m. to 4:30 p.m. Monday through Friday. Flaggers are being used to guide travelers on Colo. 119 during the lane closures. The project is anticipated to last into October.
—Chipseal roadwork: Chipseal operations throughout Boulder County began June 7. Work will take place from 7 a.m. to 4 p.m. weekdays on nine stretches of roadway in the following order: 119th Street from Oxford Road to the county line; 115th Street from Oxford to Niwot Road and on to East County Line Road; Isabelle Road from 95th Street to U.S. 287; Valmont Road from 75th to 95th streets; Jay Road from 63rd to 75th streets; Lookout Road from 75th Street to U.S. 287; Somerset and Longview roads in Niwot; 73rd/75th streets from Niwot Road to Colo. 66; North 115th from Colo. 66 to Yellowstone Road. Work will require lane closures and reduced speeds. Cyclists are advised to avoid these roads. The project is anticipated to continue into July.
—Annual paving operations: Work will take place in the following order: 79th Street between Colo. 52 and Niwot Road; Monarch Road between 79th Street and the Diagonal Highway (Colo. 119); 73rd Street between the Diagonal Highway and Niwot Road; Niwot Road between the Diagonal Highway and 73rd Street; 63rd Street between Jay Road and the City of Boulder limits; Second Avenue in Niwot; and Valmont Road between Boulder Creek and 61st Street. Construction on each segment will take approximately one week, with the exception of Second Avenue in Niwot, which should take two to three days. Paving operations will include milling of old road surface and adding a layer of new asphalt. Motorists and cyclists can expect single-lane closures in work zones. Flaggers will be used to guide travelers safely around construction operations; expect delays and use caution when passing through the zone. Work will take place from 6:30 a.m. to 4:30 p.m. Monday through Thursday, and is expected to last through August, weather permitting.
—Olde Stage Road Project: A large repaving project has begun for Olde Stage Road between Lee Hill and Lefthand Canyon drives. In addition to repaving all of Olde Stage Road, work will include widening the southern portion of the road for a four-foot shoulder to be installed in the uphill lane to provide more room for cyclists, pedestrians, emergency services providers and disabled vehicles. Drainage improvements will also be installed. The road will be reduced to one lane in multiple sections during working hours, which will result in travel delays of up to 15 minutes. Old asphalt will be milled, so speed is reduced on rough surfaces. Cyclists may consider avoiding Olde Stage Road during construction. Driveways may be inaccessible for up to 30 minutes during paving as asphalt must be allowed to cool before it can be safely crossed by motor vehicles. Crews will coordinate with homeowners during the project. This is the final phase of a larger 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 that will accommodate larger flows during potential flood events. Work will take place between 8 a.m. and 4:30 p.m. weekdays. The project is expected to last into October.
