The right lanes of northbound and southbound Plano Road at Larkspur Drive (phase 1) and then the left lanes of northbound and southbound Plano Road and the median in the same area (phase 2) may be closed to traffic from 9 a.m.-3:30 p.m. for concrete demolition and installation of new ADA ramps as well as foundations for Rectangular Rapid-Flashing Beacons to be installed at the crossing. The work is expected to be complete in late April.
