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.
