Two freeway stretches are scheduled to be closed this weekend – weather permitting, state transportation officials said Thursday.

Here are three of the main restrictions drivers will face from Friday night, Aug.18, until Monday morning, Aug. 21:

1 - Southbound Interstate 17 will be closed between Greenway Road and Northern Avenue from 9 p.m. Friday to 5 a.m. Monday for a pavement improvement project. 

Both Loop 101 ramps to southbound I-17 will be closed. Southbound I-17 on-ramps at Union Hills Drive and Bell Road will also be closed. Detours: Consider using eastbound Loop 101 to southbound State Route 51 and westbound I-10 to reach I-17 beyond the closure. Drivers on southbound I-17 also can exit ahead of the closure and detour on southbound 19th or 35th avenues.

2 - Eastbound Loop 303 will be closed between Lake Pleasant Parkway and I-17 from 8 p.m. Friday to 6 p.m. Saturday for a new interchange project.

Detour: Consider using northbound Lake Pleasant Parkway to eastbound SR 74. 

Westbound Loop 303 will be closed between I-17 and Lake Pleasant Parkway from 7 p.m. Saturday to 5 a.m. Monday.

Detour: Consider using westbound SR 74 to southbound Lake Pleasant Parkway. Note: Eastbound Loop 303 will be narrowed to one lane overnight between Lake Pleasant Parkway and I-17 from 10 p.m. Sunday to 5 a.m. Monday.

3 - Northbound 32nd Street and southbound 40th Street will be closed between I-10 and Broadway Road from 10 p.m. Friday to 4 a.m. Monday for the I-10 Broadway Curve improvement project. 

Detours: Detour route signs, including Broadway Road to northbound 40th Street, will be in place, according to ADOT.

Note: The eastbound I-10 on-ramp at 32nd Street is closed until September for construction. Consider using the eastbound I-10 on-ramp at 40th Street.
