PRESCOTT – The Arizona Department of Transportation will begin construction this week of a new roundabout at the intersection of State Route 89 and Road 4 North in Chino Valley.

For the next three weeks, crews will begin building a temporary detour on the east side of SR 89 at Road 4 North and drivers should be aware of shoulder work and increased truck traffic through the work zone, weather dependent.

The work zone will be clearly marked by temporary barricades and signage. ADOT advises drivers to allow additional time to reach their destinations and to proceed through the work zone with caution, comply with the reduced speed limit, and be alert for construction equipment and personnel.

This $2.1 million project consists of a new roundabout at the intersection of SR 89 and Road 4 North between mileposts 330.48 and 330.78. Additional work includes removal and replacement of existing pavement, drainage improvements, new pavement markings and lighting.

This project is expected to be complete by August 2015.
