Portions of La Posada Drive in Sparks will be intermittently closed this week, as Q & D Construction widens the road from two lanes to four from Omni Drive to Rockwell Boulevard, in preparation for the new Stonebrook subdivision. The road closures will take place Wednesday through Friday, on La Posada from Cordoba Boulevard to Rockwell Boulevard from 6 am to 7 pm. Detours will be in place. In June, Q & D will close the same portion of La Posada for three weeks to install a roundabout.
