The left lane of westbound Arapaho Road at each side of the intersection with Plano Road may be closed from 9 a.m.-3:30 p.m., as well as the left turn lanes of northbound Plano Road onto westbound Arapaho Road and eastbound Arapaho Road onto northbound Plano Road. ADA ramps are being installed at the intersection as part of the Duck Creek Project. The work is expected to be complete in late December.
