Attention Phoenix drivers: your weekend plans need to navigate the web of scheduled freeway closures and detours as ADOT gets down to business on several major improvement projects. First up, a segment of the northbound Loop 101 (Pima Freeway) in Scottsdale will be fully closed from 10 p.m. tonight to 5 a.m. Monday, so be ready to switch up your usual routes.

Details released by ADOT indicate the closure spans from Shea Boulevard to Pima Road/Princess Drive in North Scottsdale as part of a widening effort. For those looking to still get around, detours will be in place. ADOT suggests using the westbound Loop 202 to northbound State Route 51, which will allow motorists to basically circumvent the closures and eventually rejoin Loop 101 in northeast Phoenix. To venture out onto such a path may add more minutes to your trip, but patience will be your trusted companion through these stretches of congestion.

While the Loop 101 hogs the weekend disruption spotlight, let's not overlook the westbound Interstate 10, which will find its lane count reduced to four from State Route 143 to 32nd Street for pavement work—part of the sweeping Broadway Curve Improvement Project. The southbound SR 143 ramp to westbound I-10 is also set to be closed, alongside multiple on- and off-ramps peppered across 40th and 32nd streets. These closures are shaping up from 10 p.m. tonight to 4 a.m. Monday, with some ramps starting the closing ritual as early as 8 p.m.

The itinerary of closures keeps on growing, with the westbound Loop 202 (Santan Freeway) at McQueen Road taking a bow out of service from 10 p.m. Friday until 3 p.m. Saturday, due to bridge work. ADOT advises drivers to consider using nearby alternatives like the off-ramp at McQueen Road or the westbound on-ramp at Alma School Road, just to sidestep delays and keep their weekends moving along. And keep in mind, all of these planned operations are at the mercy of weather and other unforeseen factors, so staying tuned to ADOT's updates will be crucial.

Reflecting on the cost of such projects, it's worth citing that the fuel for these freeway improvements is not just visionary planning but also financial backing from Proposition 400, a sales tax sanctioned by Maricopa County residents. The recent approval of Proposition 479 continues to channel these voter-approved funds to jam-pack Phoenix's future with transportation developments. For those fleetingly disconnected from the pulse of real-time highway conditions, ADOT keeps you locked in with its Arizona Traveler Information site at az511.gov, or via their app for those clutch decisions on the go.
