Motorists in a Round Rock neighborhood are encouraged to find a route around construction scheduled for Wednesday. Wastewater line maintenance will require a southbound lane closure on Sam Bass Road from 9 a.m. to 4 p.m. for approximately 200 feet north and south of Westside Lane. The city of Round Rock said delays will require motorists to seek an alternate route. Weather permitting, the work will be done by 4 p.m.
