Several projects that include cleanup inside Interstate 10 tunnels will require drivers to use other routes this weekend, state transportation officials said.

These are the projects planned from Friday-Monday, Jan. 26-29, along Valley freeways:

• Eastbound I-10 will be closed between I-17 (“Stack” interchange) and SR 51 (“Mini-Stack” interchange) from 9 p.m. Friday to 9 a.m. Saturday for scheduled tunnel maintenance. 

North- and southbound I-17 ramps to eastbound I-10 will be closed. Primary detour: Eastbound I-10 traffic can detour to southbound I-17 at the Stack interchange and reconnect with I-10 near Sky Harbor Airport.

• Westbound I-10 will be closed between I-17 (“Split” interchange near Sky Harbor Airport) and Seventh Avenue from 9 p.m. Saturday to 9 a.m. Sunday for scheduled tunnel maintenance. 

The southbound SR 51 ramp to westbound I-10 will be closed. The westbound Loop 202 ramp to I-10 westbound will remain open, but traffic must exit I-10 at Seventh Street. The westbound Sky Harbor Boulevard ramp to westbound I-10 (leaving airport) will remain open, but traffic will need to exit to northbound SR 51 or eastbound Loop 202.

The westbound I-10 on-ramp at Washington Street also will be limited to traveling to northbound SR 51 or eastbound Loop 202. The southbound I-17 ramp to westbound I-10 near Sky Harbor Airport will be closed.

 Primary Detour: Westbound I-10 traffic approaching the closure can use northbound I-17 to connect with I-10 at the Stack interchange (north of Van Buren Street).

• Southbound State Route 143 ramp to eastbound I-10 and the eastbound I-10 on-ramp at Broadway Road will be closed from 10 p.m. Friday to 4 a.m. Monday for the I-10 Broadway Curve improvement project. 

Broadway Road also will be closed between 48th and 52nd streets. The I-10 connector ramp between 48th Street and Broadway Road will be closed. Detours: Use alternate routes to connect with eastbound I-10. 

Note: Westbound US 60 HOV ramp to westbound I-10 also will be closed this weekend (traffic will use the primary US 60 ramp to westbound I-10).

• Eastbound I-10 will be narrowed to three lanes overnight between 24th and 32nd streets near Sky Harbor Airport from 8 p.m. Sunday to 5 a.m. Monday for bridge work.

Note: The eastbound I-10 off-ramp at Ray Road will be closed from 10 p.m. Friday to 6 p.m. Saturday for construction. Consider exiting at Chandler Boulevard.
