Major overnight work will close stretches of three Valley freeways
State transportation crews will close several freeway segments across the Phoenix metropolitan area this weekend as part of pavement, widening and improvement projects. The restrictions begin late Friday evening and continue through early Monday, affecting northbound State Route 51, parts of Loop 202 in Chandler and sections of southbound Loop 101 in the East Valley.
What is closing and when
According to the Arizona Department of Transportation, the closures are scheduled to start Friday night and reopen by Monday morning. The most consequential closures for north Phoenix commuters are on SR 51, while drivers in the East Valley should expect ramp and lane shutdowns around Mesa and Chandler.
- Northbound SR 51: Closed between the I‑10 Mini Stack interchange and Colter Street from 9 p.m. Friday to 5 a.m. Monday for pavement work. All I‑10 and Loop 202 ramps to northbound SR 51 also will be closed.
- Loop 202 (Chandler): Eastbound lanes closed between McQueen and Lindsay roads from 10 p.m. Friday to 5 a.m. Monday for a widening project. Eastbound on‑ramps at Dobson, Alma School and Arizona avenues will be closed.
- Loop 101 (East Valley): Southbound lanes closed between McKellips Road and University Drive from 8 p.m. Friday to 5 a.m. Monday for pavement improvements. Ramps from eastbound and westbound Loop 202 to southbound Loop 101 will also be closed; southbound on‑ramps at Indian School, Thomas and McDowell roads will be shut down.
"Drivers should allow extra travel time and use detour routes as needed for these weekend freeway restrictions."
Suggested detours and local impacts
ADOT is recommending alternate routes to reduce delays. For northbound SR 51 travel to north Phoenix, using northbound Interstate 17 is suggested. Eastbound Loop 202 drivers in Chandler can detour via eastbound Pecos or Germann roads. Motorists affected by the Loop 101 closure may use surface streets such as southbound Hayden Road or McClintock Drive to reach westbound Loop 101 or bypass the closed segment.
These weekend work windows are aimed at completing repairs and lane additions while minimizing daytime disruption, but they concentrate traffic on fewer routes during peak travel times around the closures. Commuters who usually rely on these freeway segments should plan for longer travel times, consider alternate corridors or adjust travel to nonpeak hours when possible.

Why this matters locally
These targeted weekend closures reflect a broader pattern of concentrating major maintenance and expansion work in overnight windows to limit daytime congestion. Still, Phoenix-area drivers are reminded that even temporary shutdowns can ripple across the regional network, filling parallel freeways and surface streets. If your commute or weekend travel plans include any of these corridors, allow additional time and follow posted detours and traffic control. ADOT and local traffic partners typically update traveler information as work progresses, so checking agency alerts before heading out will help avoid surprises.
