1. Plano Parkway-Preston Road intersection

Traffic disruptions intensified in October at the intersection of Plano Parkway and Preston Road as crews close lanes and worked to widen Preston Road near the major intersection. Since December most of the construction had been confined to the intersection’s large median, where crews were building new eastbound lanes that will run closer to their westbound counterparts and allow for more separation between the intersection and President George Bush Turnpike to the south. The Plano engineering department expected most of the traffic slowdowns to continue through December. The most intensive work is expected to take place from 9 a.m.-3 p.m. on weekdays.
