The new southbound 48^th Street bridge is scheduled to open next week, but first crews will be working through the weekend to get the span ready.

Southbound State Route 143 will be closed between Loop 202 and Interstate 10 from 10 p.m. Friday, Jan. 20, to 4 a.m. Monday, Jan. 23, according to the Arizona Department of Transportation.

Crews with the I-10 Broadway Curve Improvement Project will be completing paving and ramp reconfiguration to align with the new southbound 48th Street bridge over I-10.   At the same time, the following ramps will be closed:

• The ramps from Loop 202 to southbound SR 143.
• The southbound SR 143 on-ramps at Washington Street, Sky Harbor Boulevard and University Drive. 
• Eastbound I-10 off-ramp at 48th Street.
• Westbound I-10 on-ramp at Broadway Road. 

Detour:

• Southbound SR 143 detour for eastbound I-10 and westbound Loop 202 drivers: Use westbound Loop 202 to eastbound I-10 to access destinations south of the closure. 
• Southbound SR 143 detour for eastbound Loop 202 drivers: Use eastbound Loop 202 to southbound Loop 101 to westbound US 60 to access destinations south of the closure.
• Northbound SR 143 detour for eastbound I-10 drivers: Use eastbound I-10 to westbound Baseline Road to northbound 48th Street to access northbound SR 143.

Airport Traffic: From Loop 202, use southbound 44th Street. From I-10, use Buckeye Road or 24th Street. Access to the airport from northbound SR 143 is not affected.

When southbound SR 143 reopens on Monday drivers will use the new southbound 48th Street bridge over I-10. The existing southbound 48th Street bridge over I-10 will be permanently closed and eventually removed. The new northbound 48th Street bridge over I-10 is anticipated to open later this spring.

In addition the weekend, the westbound I-10 ramp to eastbound US 60 and the westbound I-10 on-ramp at Baseline Road will be closed for bridge work from 10 p.m. Fri., Jan 20 to 4 a.m. Mon., Jan. 23. 

• Westbound I-10 to US 60 ramp detour: Use westbound I-10 to westbound Broadway Road to eastbound I-10 to access eastbound US 60.
• Westbound Baseline Road detour: Use westbound Baseline Road to northbound 48th Street to access State Route 143. Continue west on Baseline Road to 40th Street to access westbound I-10.

Eastbound Baseline Road detour: Use eastbound Baseline Road to northbound Priest Drive to access eastbound US 60. Continue north on Priest Drive to westbound Broadway Road to northbound 40th Street to access westbound I-10. Continue north on Priest Drive to westbound University Drive to access SR 143.
