The Arizona Department of Transportation advises drivers to prepare for lane restrictions along State Route 377 between Holbrook and Heber-Overgaard as a new shoulder widening project starts on Wednesday, April 1.

Drivers should expect the following restrictions from 6 a.m. to 4 p.m. weekdays:

• SR 377 will be reduced to one lane only in 2-mile segments with alternating north- and southbound travel between mileposts 8-13.
• Vehicles will be directed through the work zone by flaggers and a pilot car. 
• A 12-foot vehicle-width restriction will be in place.
• Drivers need to be prepared to make frequent stops when approaching and driving through the work zone and use caution around construction personnel and equipment while the restrictions are in place. 
• Drivers can also use State Routes 77 and 277 as a detour.
• No work is scheduled on weekends or state holidays.

The project is anticipated to be completed by the fall.

The Arizona Department of Transportation advises motorists that construction is underway on the US 93 Cane Springs Improvement project located north of Wikieup.

Crews will be working during the next several weeks to clear the work zone in preparation of mobilizing construction equipment to the area. Most of the construction will take place off of US 93 and will have limited impact to motorists. The speed limit will be reduced to allow for heavy equipment to safely access the work zone.

Located approximately 13 miles north of Wikieup, the project will include the following elements:

• Widening a 4-mile segment of US 93 from a two-lane undivided roadway to a 4-lane divided highway between mileposts 106 and 110.
• Constructing two new bridges over Cane Springs Wash and removing the existing bridge (milepost 109).
• Improving and/or installing drainage and sediment-control facilities, including culverts, pipes and ditches.
• Reconstructing the intersection turnout at Upper Trout Creek Road.

The project is expected to be completed in 2027.

• Blasting closures: I-40 fully closed between Stockton Hill Rd and Beale St (MP 51–48) starting 8 p.m. on March 12, 19, 26, and April 2. Expect delays up to 30 minutes.
• Lane restrictions on I-40 and US 93 from 9 p.m.–5 a.m. (Mon–Thu).

Expect delays, drivers can use I-17 as alternate route

A guardrail replacement project along the State Route 89A switchbacks at the north end of Oak Creek Canyon is scheduled to begin Wednesday, April 1.

SR 89A is scheduled to be narrowed to one lane at times along the 3-mile stretch (mileposts 387-390) between Pine Flat Campground and the Oak Creek Vista scenic overlook. Work typically will take place from 6 a.m. to 6 p.m. Monday through Thursday and from 6 a.m. to noon on Friday. Flag crews and a pilot car will guide traffic through the work zone. A 12-foot vehicle width restriction will be in place.

When around-the-clock restrictions are needed, temporary traffic signals will be used to allow traffic to travel through the work zone one direction at a time. While restrictions are in place, drivers who would normally use SR 89A in the switchbacks area should consider an alternate route along Interstate 17 and SR 179 to travel between Flagstaff and Sedona.

The project will replace older sections of guardrail, reconstruction sections of curb and gutter and install concrete barriers in some areas. Work is scheduled for completion by late summer (2026).

Lane restrictions to continue weekdays through April

The Arizona Department of Transportation advises that temporary partial driveway closures on State Route 289 are scheduled to begin Wednesday, April 8, as work continues on a pavement rehabilitation project.

Driveways will be closed for 15 minutes to allow placement, compacting and curing of asphalt.

Drivers should also plan for daytime lane restrictions on SR 289 (Ruby Road) near Peña Blanca Lake from 5 a.m. to 6:30 p.m. weekdays through April. The following lane restrictions are scheduled:

• Daytime lane restrictions on east- and westbound SR 289 (Ruby Road) between mileposts 1 and 9
• Flagging operation in the project area
• A 14-foot vehicle width restriction
• 25 mph speed limit in the work zone

Drivers should allow extra travel time, use caution, be prepared to slow down and merge safely when approaching and traveling through all work zones.

Schedules are subject to change due to weather and other unforeseen circumstances.
