All southbound lanes on Interstate 17 were expected to close Thursday night as crews worked on installing new traffic-flow sensors.

The closures will begin around 9 p.m. between the I-10 "Stack" interchange and 19th Avenue. The road will reopen around 5 a.m. on Friday, according to the Arizona Department of Transportation.
