 These restrictions will be in place starting between 6 and 7 p.m. and ending around 6 or 7 a.m. through Saturday. The restrictions are needed to accommodate earthwork and the placement of temporary concrete barriers as part of the I-17 Improvement Project. Those traveling through the area should be aware of reduced speeds and construction personnel and equipment and allow for extra time to reach your destination. The I-17 Improvement Project should be completed next year.
