ROUND ROCK, Texas (KXAN) — A semi-truck is causing a big headache for drivers in Round Rock after police said it knocked down power lines Wednesday afternoon.

Because of those downed lines, police said U.S. 79 is closed at the intersection with Mays Street. Officers noted, though, traffic is still moving on Mays Street as of 4 p.m.

Drivers may want to seek out ways around this section of U.S. 79 for the time being.
