The last scheduled weekend closure for the Interstate 17 pavement improvement project begins Friday night on a stretch of the southbound lanes between State Route 74 and Loop 303 in north Phoenix, according to the Arizona Department of Transportation.

I-10 will be off-limits from the I-17 “Split” interchange near Phoenix Sky Harbor International Airport to the I-17 “Stack” interchange near McDowell Road from 9 p.m. Friday to 5 a.m. Monday. The closure, which includes the Deck Park Tunnel through downtown Phoenix, is for deck joint work as part of pavement improvements, ADOT said.

Scottsdale drivers thinking of taking the Loop 101 this weekend may need to take a detour. The Arizona Department of Transportation said the northbound lanes of the freeway will be closed from Friday at 10 p.
