A gas leak has closed the eastbound lanes of Farm-to-Market Road 1709 past Commerce in Southlake just east of state Highway 114.
Construction crews ruptured an 8-inch gas line, closing the road and prompting the evacuation of The Eye Group building.
Parents whose children attend the nearby KinderCare at 3115 E. 1709 are asked to pick up their children early.
It is expected to take up to 3 hours to repair the breach.
Drivers are cautioned to avoid the area through rush hour Thursday.
