The light rail extension Phoenix voters approved for the State Capitol area in 2015 isn't going to be built on its current plan. The next line the city is pursuing runs about 10 miles west along Indian School Road to Maryvale, and it isn't expected to carry riders until 2036. One thing is still undecided. Before engineering starts, Phoenix and Valley Metro have to choose whether the new line connects to the existing B Line at Indian School Road and Central Avenue or at 19th Avenue and Camelback Road. That choice decides how the west side reaches the rest of the system, and it's still open.
The loop that stopped near the Capitol
The Capitol Extension, known locally as CAPEX, was meant to be short. A Valley Metro fact sheet from spring 2025 described a 0.8-mile extension forming a 1.6-mile loop. It would have run west on Washington Street from 3rd Avenue, south on 15th Avenue, east on Jefferson Street, and back to 3rd Avenue, with two stations. Valley Metro CEO Jessica Mefford-Miller put its cost at $624 million, KJZZ reported. The same report cited city documents putting the companion I-10 West line, called 10WEST, at $2.7 billion.
That route was never final. By August 2025, Phoenix New Times reported that three alternatives were still under study. One was a mostly at-grade alignment on 15th Avenue through the Woodland Historic District, where residents said five homes and three businesses could be demolished. Woodland residents told the outlet they preferred a mostly elevated 16th Avenue South option as the least destructive choice.
The route debate was overtaken by state politics. As KJZZ reported after the vote, a 2023 Arizona law banned light rail within 50 yards of the Capitol. It also gave a legislative committee some authority to approve contracts for stations elsewhere in the surrounding area. In December 2025, Republican legislative leaders sent letters to the City Council opposing the project. KJZZ reported that their letters claimed the project would cost $250 million per mile, serve fewer than 1% of Valley commuters, and recover 7.6% of its costs from fares. Gov. Katie Hobbs' budget director wrote to the council that the city and state wouldn't need to sign any contracts subject to that committee's review to build the lines.
Federal funding put the city under time pressure. Phoenix was seeking about $250 million in federal grants for CAPEX and more than $1.2 billion for 10WEST, with applications due in April 2026. City staff said rerouting away from the Capitol area would make that deadline virtually impossible to meet.
A 7–2 vote after a 10-hour meeting
On Jan. 27, 2026, after what KJZZ described as a marathon 10-hour meeting, the Phoenix City Council voted 7–2 to shelve CAPEX and the I-10 West line. The council chose to speed up the Indian School Road route to the Desert Sky Transit Center in Maryvale instead. The city's announcement the next day confirmed that Valley Metro would leave CAPEX project development and the federal Capital Investment Grant process.
Councilmember Betty Guardado, who voted with the majority, described the decision as a matter of order, telling KJZZ the city was:
"sequencing them responsibly."
Councilmember Laura Pastor and Councilmember Anna Hernandez cast the two votes to keep CAPEX and I-10 West moving. Hernandez argued that voters had approved the work and the city should honor that commitment. Mayor Kate Gallego framed the choice as a question of political feasibility.
So downtown's next rail project was decided by which route could get past the Legislature's objections and the federal grant calendar. The west-side line moved to the front of the queue because it doesn't need anything from the Capitol.
What moved to the front of the line
The West Phoenix route isn't new. Phoenix City Council adopted it as the Locally Preferred Alternative in May 2024. Valley Metro's Q2 2026 fact sheet lists four reasons it was selected. It showed the highest ridership of the options studied, it serves the most transit-reliant customers, it has the strongest economic development potential, and it reaches the largest number of affordable housing units in the area.
Here's how the two projects compare:
| Capitol Extension (CAPEX) | West Phoenix Extension | |
|---|---|---|
| Length | 0.8-mile extension forming a 1.6-mile loop | About 10 miles |
| Route | Washington St., 15th Ave., Jefferson St. | Indian School Rd. to 75th Ave., south to Thomas Rd., west to Desert Sky Transit Center |
| Status | Out of federal grant process since January 2026 | In planning through 2027 |
| Cost figure on record | $624 million, per Valley Metro's CEO | Funding still to be determined |
| Projected opening | Shelved by council vote | 2036 |
The fact sheet also includes an optional extension farther west on Thomas Road, ending near Banner Estrella Medical Center. A 2024 Valley Metro analysis projected an average of 16,600 weekday trips on the route by 2050, Axios Phoenix reported in August.
The junction is the decision still open
The west end of the line is set at Desert Sky. The east end isn't. Valley Metro is weighing two places to tie the line into the existing B Line, either Indian School Road and Central Avenue or 19th Avenue and Camelback Road. Valley Metro and the city will bring an updated recommendation and a proposed connection point to the Phoenix City Council and the Valley Metro Board after technical analysis. That analysis also covers potential stations, park-and-ride locations, a maintenance facility assessment, and the concept of operations. The fact sheet doesn't give a date for that vote.
That's why this fall's outreach mattered. Valley Metro and the city held three open houses with no formal presentation, where people could talk one-on-one with staff:
- Wednesday, Aug. 19, at Desert West Community Center, 6501 W. Virginia Ave.
- Saturday, Sept. 19, at Maryvale Community Center, 4420 N. 51st Ave.
- Wednesday, Oct. 14, at Steele Indian School Park Memorial Hall
The August session asked attendees to weigh the pros and cons of the two connection options, along with destinations, priorities, timeline, and business assistance. In Valley Metro's summary, attendees named Grand Canyon University, Westgate and State Farm Stadium, Banner Estrella Medical Center, the Desert Sky Transit Center, and connections to downtown and Central Avenue as places they hoped the line would serve. Those were requests, and none of them are committed stops. Attendees also asked for faster, more reliable service, shade and cooling at stops, better transfers and park-and-rides, safer and more accessible streets, and construction protections for businesses.
Axios reported that people who spoke to it at the August meeting were largely in favor. Earlier rounds of outreach had drawn concerns about safety and traffic disruption. Updates and signups are on Valley Metro's West Phoenix Extension page.
A decade of milestones before the first ride
The schedule has already moved once. In January, KJZZ described possible construction in 2031 and an opening in 2037. The current timeline, as reported by Axios in August 2026, looks like this:
- Planning runs through 2027.
- If the city approves the route, engineering begins in 2028.
- Construction is slated to start in 2032.
- The line is expected to open in 2036.
Phoenix's last rail project gives the clearest preview of what the construction years will bring. The $1.3 billion South Phoenix extension, which opened in 2025, blocked access to some stores and restaurants during construction, according to Axios. The outlet noted that the same problem will come up again on Indian School Road. During the South Phoenix work, the city and Valley Metro ran a pilot program that gave 295 grants worth more than $1.2 million to 95 local businesses. The city plans to offer similar financial help on the West Phoenix project, plus free business assessments and access signage.
What changes on the existing lines now
Riders on today's system get a smaller change sooner. Valley Metro posted new A Line and B Line schedules effective Monday, Oct. 26. The same service package adjusts PHXLink microtransit and a long list of bus routes. The city's service-change notice specifically lists Route 1 on Washington Street and Route 3 on Van Buren Street, two downtown corridors close to where CAPEX would have run. Updated timetables are on Valley Metro's Oct. 26 schedule page.
For anyone who rides the B Line along Central Avenue or near Camelback Road, the connection decision is the part of this project to follow. Whichever junction the council picks will become the transfer point between the west side and the rest of the system, from 2036 onward.
Transit plans like this one change what different parts of Phoenix offer over the next decade, and pricing a home well means knowing what's actually decided and what's still being planned.
