 Work will initially occur on the shoulders during the day. Two travel lanes will be maintained during daytime hours. In addition, Highway 69 will be narrowed to one lane in each direction between Prescott Lakes Parkway and Heather Heights from 8 p.m. to 6 a.m. Sunday nights through Thursday mornings. This $10 million project is expected to take nine months to complete. I'm Lindsay Draper reporting.
