5600 South & 1900 West Periodic Lane Closures – Final Striping 

Crews will continue periodic daytime and nighttime lane closures along 5600 South and 1900 West through mid-July to complete final roadway striping and permanent pavement markings. This work includes installing final lane lines, directional arrows, crosswalk markings, and other pavement markings that organize traffic movements to improve safety.

Drivers should expect intermittent lane closures, shifting traffic patterns, and brief delays while work is underway. Please slow down, follow posted signage, and use caution when traveling through the work zone.

Daytime Finish Up Work Continues Through July 

Crews will continue daytime improvements along the corridor throughout July. Work will include sign and fence installation, gore painting, which is the white striped pavement markings that separate travel lanes from ramps and merge areas.

Most work will take place along the roadway shoulders, so drivers should expect minimal to no travel delays. Drivers are encouraged to slow down, stay alert, and watch for crews working near the roadway.

Ongoing Activities

Overnight I-15 Southbound Lane Closures 

Crews will continue overnight lane closures on I-15 southbound through mid-July to complete final pavement marking work. Activities include grinding off old lane lines before installing new permanent pavement markings, creating a clean roadway surface for the final striping.

Drivers should expect overnight lane restrictions and use caution while traveling through the work zone.

I-15 Lane Closures & Shifts

Crews will complete nighttime intermittent lane shifts and closures on I-15 in both northbound and southbound directions through July for profile and concrete grinding activities. During this work, traffic will shift to the three middle lanes. Pavement grinding smooths the concrete surface to improve the ride quality for drivers. 

Plan ahead and expect delays during peak travel times. 

Traffic Pattern Change – Raised Median Installation

Recently, crews installed a new concrete raised median on 5600 South between 2050 West and 1900 West. This work will introduce new left-turn restrictions in the area to improve safety, reduce conflict points, and help improve traffic flow through the corridor. 

During construction, one westbound lane on 5600 South will be temporarily restricted during daytime work hours. Drivers are reminded to slow down, watch for changing traffic patterns and use extra caution while traveling through the work zone.
