    Pavement PreservationOn Monday, October 25, the Pima County Department of Transportation, along with its contractor, KE&G Construction, will begin water line tie-in work at the intersection of Sunrise Drive and Kolb Road.

    Project Activity

    The right turn lane from Sunrise Drive onto Kolb Road will be modified in order to perform the water line tie-in work, and Kolb Road, heading north will have a closed bike lane. There will be one left turn and one right turn lane for east and westbound traffic.

    Please remember to share the roadway with bicyclists during construction.

    Project Scope

    Project improvements include the widening of Kolb Road from a 2-lane roadway to a 3-lane roadway with multi-use paved shoulders suitable for bicycle use, sidewalks, drainage, and landscaping. The median treatment will be a two-way left turn lane. A roundabout will be installed at the Territory Drive and Kolb Road intersection. This project is part of the 1997 HURF Bond Program, specifically DOT 32 and is expected to be completed late spring of 2022.

    Please approach the area with caution and obey all traffic control devices. Traffic control changes and speed reductions will occur as work progresses.
