Crews working for the City of Peoria are scheduled to start rebuilding 67th Avenue at the Happy Valley Road intersection in mid-October. The plan is to reconstruct the outside lanes, add a median island on the south side and build dual left turns for northbound traffic. Peoria doesn't own that intersection, though. The city's project page says 67th Avenue is a Peoria road, while the 67th Avenue and Happy Valley Road intersection belongs to the City of Phoenix, and Phoenix's Streets Department manages its signals. East of that light, Phoenix is running its own construction project on Happy Valley Road, and it keeps traffic to one lane in each direction through summer 2027.
If your daily drive crosses that corner, you're dealing with two projects run by two cities on two calendars. The Peoria work wrapping up won't, on its own, make the trip toward I-17 any faster.
The City Line Runs Through the Intersection
Peoria annexed this stretch of 67th Avenue from Maricopa County in 2007. The city's 67th Avenue Corridor Improvement Project covers the road from Pinnacle Peak Road north to Happy Valley Road. Plans call for three travel lanes and a bike lane in each direction, burying the overhead utilities, and new curb, gutter, sidewalk, storm drains, streetlights and landscaping. Sundt Construction is the contractor. Completion is scheduled for 2027.
Peoria's own FAQ answers the question most drivers at that corner would ask. Asked whether the project will fix the timing of the signals at 67th and Happy Valley, the city says the intersection is managed by Phoenix's Streets Department, Traffic Management. Peoria can rebuild the lanes that feed the light, but Phoenix runs the light itself.
That split matters more this fall because the Phoenix project starts at that same corner. Phoenix's Happy Valley Road Improvement Project covers four miles of Happy Valley from 67th Avenue east to 35th Avenue. Peoria's corridor page sends readers to Phoenix for details on it.
What Peoria's Crews Have Scheduled Next
The newest detailed bulletin from Peoria's project team is dated September 11, 2026. Here's its sequence, with the caveat that it's a forecast. The bulletin says weather, materials and crew availability can all move these dates.
- Now through about mid-October. Traffic on 67th Avenue runs on the east side of the road, one lane each way, with left turns restricted. Hatfield Road is closed where it meets 67th on the west side. During the Hatfield work, the road stays open to local residents coming and going from the west.
- Mid-October, for about three to four weeks. Work moves to the Happy Valley intersection, and 67th Avenue traffic shifts to the middle of the road, with lane and possibly turn restrictions.
- Around early November. Traffic moves to the curb lanes so crews can work in the middle of 67th Avenue.
The same bulletin lists drainage work nearby. Crews are digging out the Hatfield Road basin and installing weir walls and a spillway, which help control water levels during big storms. They're also building retaining walls with a gabion facade in the 65th Avenue wash, east of 67th. From Pinnacle Peak Road to Hatfield Road, the speed limit is reduced to 30 mph.
That middle-lane phase is the one to plan around. Lanes and turns will both be limited at the busiest corner on the corridor for most of a month, and Phoenix will still be controlling the signal throughout.
East of the Light, Phoenix Runs a Longer Clock
Phoenix describes this part of Happy Valley Road as a major arterial that connects commuters to Interstate 17. It currently switches back and forth between two and three travel lanes, with curb, sidewalk and medians that come and go. The project adds a third lane between 62nd and 56th avenues and between 51st and 47th avenues, plus new traffic signals at 61st and 47th avenues, raised medians and buffered bike lanes. Part of the job is drainage work to handle runoff from Ludden Mountain.
Phoenix's September 18, 2026 notice moved traffic in the 51st-to-39th-avenue work zone to the outer lanes. It's one lane each way, and left turns are allowed only at signalized intersections. That phase runs through January 2027. Two turn restrictions fall in the next few weeks. Left turns at 49th Avenue are restricted through October 14, and then at 47th Avenue from October 14 to 22. Right turns stay open, and drivers can use the other intersection. Phoenix has also posted a notice that work in the 67th-to-35th zone may start as early as 4 a.m. so concrete can cure slowly.
Here's how the two projects compare.
| 67th Avenue Corridor | Happy Valley Road, 67th to 35th | |
|---|---|---|
| Run by | City of Peoria | City of Phoenix |
| Stretch | Pinnacle Peak Rd to Happy Valley Rd | 67th Ave to 35th Ave |
| Current lane setup | One lane each way, left turns restricted | One lane each way through the project |
| Posted finish | 2027 | Late spring 2027, with restrictions through summer 2027 |
| Hotline | 602-532-6250 | 623-825-3444 |
Phoenix's own page gives two different end markers. It expects to finish construction in late spring 2027, but it also says long-term restrictions, lane closures, sidewalk closures and detours will last through summer 2027. So when Peoria's intersection phases wrap up, likely before the end of this year if the September schedule holds, Happy Valley heading east will still be down to one lane each way.
The Closures That Aren't About Cars
The New River Trail is closed at Hatfield Road, between Pinnacle Peak and Happy Valley, through December 2026. Crews are digging there to install a 90-inch storm drain pipe that will carry stormwater out during heavy storms. That end date first showed up in a project update posted in spring 2025, so treat December as the posted target and not a confirmed reopening. Peoria's interactive trails map, which also shows bike lanes, parks and transit, is the best place to plan a different loop until then.
The trail closure and the Hatfield Road work are part of the same project. Peoria and the Flood Control District of Maricopa County are building a regional drainage system that sends stormwater through a box culvert at Hatfield Road to New River. The goal is 100-year-level drainage protection for the area. The project is paid for by Peoria's Capital Improvement Program, the Flood Control District and the State of Arizona. Most of the digging, from the Hatfield basin to the wash east of 67th, is for drainage and not for the extra lanes.
Phoenix's project also includes sidewalk closures along Happy Valley, so the same advice applies to anyone walking or biking east of 67th.
What the Finished 67th Avenue Changes at Your Usual Stops
Two of the biggest destinations on this stretch sit just south of the intersection. Life Time's Happy Valley-Peoria club is at 24700 North 67th Avenue. Christ's Church of the Valley's Peoria campus is at 7007 W Happy Valley Road and holds services on Saturday, Sunday and Monday. Peoria has already added a new traffic signal at the shared main entrance for CCV and Life Time. The city expects that signal, along with the widening, to cut down on the congestion on 67th Avenue around church events.
The finished design adds raised median islands on 67th Avenue between that Life Time and CCV entrance and Happy Valley Road. The city says they're there to manage access and improve safety. At the intersection, the south leg gets dual left-turn lanes and a dedicated right-turn lane, and the north leg gets dual left-turn lanes. Mochilero Kitchen, at 6791 W Happy Valley Road, Suite 100, describes itself as easy to reach from 67th and Happy Valley. Once the medians are in, how you turn into places near that corner may change, so it's worth checking the route before the new lanes open.
Through all of this, Peoria says it's keeping access open to homes and businesses, even if the route isn't the most direct. If your water service or utilities are interrupted without notice, call the project hotline at 602-532-6250. Questions about Happy Valley east of 67th go to Phoenix at 623-825-3444 or [email protected]. Since Phoenix runs the signal, signal-timing complaints at 67th and Happy Valley go to Phoenix as well.
If you live along 67th Avenue and you're wondering what the widening means for your street, your commute or your home's value once the work is done, I'm happy to talk it through with you.
