Interstate closures planned this weekend in Pennsylvania, Missouri, Arizona

A section of the Pennsylvania Turnpike and I-70 in Kansas City will be completely closed this weekend for construction projects, while I-17 near Anthem, Arizona, north of Phoenix, will be reduced to one lane for part of the weekend.

Pennsylvania Turnpike

The Pennsylvania Turnpike Commission announced a closure is planned between the Lehigh Valley Interchange (exit 56) and the Mahoning Valley Interchange (exit 74) on I-476, also known as the Turnpike’s Northeastern Extension. The interstate will be closed in both directions from 9 p.m. Friday, Sept. 6, until 4 a.m. Monday, Sept. 9.

PTC says the closure is needed for crews to demolish the current bridge that carries the Turnpike over State Route 309 and replacing it with a new steel superstructure.

Southbound through traffic can exit at Pocono exit 95 and take I-80 East to Pennsylvania 33 South (25.5 miles) to U.S. 22 West (23.6 miles) to I-476 South at exit 56 (15.8 miles).

Northbound traffic can use exit 56 and take U.S. 22 East to Highway 33 North to I-80 West to I-476 at exit 95.

I-70 in Kansas City

The Missouri Department of Transportation will completely close I-70 in both directions for a seven-mile stretch between I-435 and I-470 from 9 p.m. Friday through 5 a.m. Monday.

The closure is for the demolition of the directional ramps from southbound I-435 to eastbound I-70 and northbound I-435 to westbound I-70.

Ramp closures will begin Thursday night as crews will close the ramps from northbound I-435 to I-70 West and from southbound I-435 to I-70 East at 7 p.m. These ramps will be closed until approximately spring 2020.

MoDOT says drivers must follow the signed detour using I-470 or find an alternate route.

I-17 north of Phoenix

Arizona DOT crews will reduce I-17 Southbound to one lane between Daisy Mountain Drive and Pioneer Road near Anthem, north of Phoenix, on Friday, Sept. 6, and Saturday, Sept. 7.

ADOT warns drivers to allow extra travel time and be prepared to slow down and merge into one lane.

The lane closure will be in effect from 5 a.m. to 10 p.m. both Friday and Saturday.
