A section of eastbound Interstate 10 will be closed this weekend for a traffic shift that will permanently close  an SR 143 on-ramp, state transportation officials said Wednesday.

Drivers should plan and expect delays when eastbound I-10 closes between State Route 51 and US 60 from 10 p.m. Friday, June 21, to 4 a.m. Monday, June 24, for work being done by the Arizona Department of Transportation.

The following ramps will be closed: 

• The loop ramp from southbound SR 143 to eastbound I-10.
• The ramp from southbound Interstate 17 to eastbound I-10. 
• The westbound Loop 202 ramp to eastbound I-10.
• The ramps from southbound SR 51 to eastbound I-10.
• The HOV ramp from eastbound I-10 to eastbound Loop 202.

The following ramps will be closed from 8 p.m. Friday, June 21, to 4 a.m. Monday, June 24: 

• The eastbound I-10 on-ramps at Third, Seventh and Jefferson streets, Buckeye Road, 24th, 32nd and 40th streets and Broadway Road.
• The southbound I-17 on-ramps at Seventh Avenue and Seventh Street.
• The southbound SR 51 on-ramp at McDowell Road.

Detour: Use eastbound Loop 202 to southbound Loop 101 to westbound US 60 or westbound Loop 202 to reach eastbound I-10 beyond the closure. Drivers traveling on southbound I-17 can use westbound I-10 to eastbound Loop 202.

West Valley drivers heading to the Southeast Valley can bypass the closure by using Loop 202. From I-10 and 59th Avenue, travel south and east to connect with eastbound I-10 south of Chandler Boulevard. 

The southbound SR 143 ramp to eastbound I-10 will permanently close at 8 p.m. Friday. Drivers can use the eastbound I-10 on-ramp at Broadway or Baseline roads instead.

A new flyover ramp is scheduled to open later this year, according to ADOT.

When eastbound  I-10 reopens, drivers can expect a new lane configuration, ADOT officials said, adding crews will remove the lane split between 48th Street and Broadway Road.
