'''State Route 30''' ('''SR 30'''), also known as the '''Tres Rios Freeway''', is a planned freeway in the southwest part of the Phoenix metropolitan area. It is planned as a reliever for Interstate 10 five miles (8 km) to the north and will run through the communities of Buckeye, Goodyear, Avondale, and Phoenix.<ref name=SR30MAG />

In earlier planning stages, the freeway was referred to as '''State Route 801''' ('''SR 801''').

SR 30 will have three segments: a western segment from SR 85 to Loop 303, a central segment from Loop 303 to Loop 202, and an eastern segment from Loop 202 to I-17.

==Route description== SR 30 is planned to begin at SR 85 along the Hazen Road alignment, about one mile (1.6 km) south of downtown Buckeye. It will then travel northeast for 10 miles (16 km) before intersecting Loop 303 between Broadway Road and Southern Avenue in Goodyear. SR 30 will then head east for five miles (8 km) before turning southeast at the Agua Fria River and running along the Southern Avenue alignment for {{convert|2.5|mi|km}}. While along the Southern Avenue alignment, frontage roads will accompany the road to provide access to local communities. SR 30 will then head back northeast for {{convert|7|mi|km}} before intersecting Loop 202 just south of Broadway Road in Phoenix. SR 30 will then continue to travel northeast for {{convert|4.5|mi|km}} before meeting its eastern terminus by intersecting the Interstate 17 at the Durango Curve in Phoenix. SR 30 will be {{convert|29|mi|km}} in length when fully complete.<ref name=SR30MAG /><ref name=SR30:L303toL202>{{cite web |title=State Route 30: Loop 303 to Loop 202 Study |url=https://azdot.gov/planning/transportation-studies/state-route-30-loop-303-loop-202-study |website=Arizona Department of Transportation |access-date=April 21, 2022 |date=April 28, 2020}}</ref>

==History== A freeway along the planned SR 30 corridor, titled the Buckeye Expressway, was originally proposed in 1957 as the planned route for Interstate 10 into Phoenix. This plan was later abandoned, and I-10 was re-routed northwards along the present Papago Freeway alignment.<ref>{{cite web |title=Recommended Major Street and Highway Plan |url=https://arizonaroads.com/pics/urban1960.jpg |access-date=29 April 2023}}</ref>

In November 2004, Maricopa County voters approved an extension to an existing sales tax funding regional transportation improvements.<ref>{{cite web |title= About MAG: Proposition 300 and 400 |url= https://www.ourmomentumplan.com/about#:~:text=What%20is%20Proposition%20300%3F%20Proposition%20300%20was%20a,Loop%20202%2C%20and%20State%20Route%2051%2C%20Piestewa%20Freeway. |website=Maricopa Association of Governments |access-date=February 26, 2022}}</ref> A significant portion of those funds will go toward improvements of I-10, which experiences significant volumes of traffic in the southwest part of the Valley. However, rapid growth in the neighboring communities of Buckeye, Goodyear, and Avondale is expected to worsen the congestion on I-10, necessitating the construction of a reliever route.

The Arizona Department of Transportation (ADOT) first identified the need for a route along the current SR 30 corridor in June 2005.<ref name=SR30PIM>{{cite web |title=State Route 30 (SR 30) Study – SR 303L to SR 202L Public Hearing |url=https://azdot.gov/sites/default/files/2019/08/sr30-public-hearing-presentation-051119.pdf |website=Arizona Department of Transportation |access-date=February 26, 2022 |date=May 11, 2019}}</ref> The route was planned to run parallel 5 miles (8 km) south of I-10 through the cities to provide relief. It would run through largely undeveloped land, reducing the impact on residential communities. Due to the extension of the sales tax in 2004, funds were available to help build SR 30.

In response to a budget shortfall brought on by the Great Recession, the Maricopa Association of Governments (MAG) voted to suspend funding to numerous projects in October 2009, including SR 30.<ref name=SR30PIM /> While not removing SR 30 from the long-term regional transportation plan, the removal of the funding would effectively postpone the construction of the route until at least 2026. The plan had originally indicated a construction timeline between 2021 and 2025.

In October 2016, it was announced that ADOT was exploring the possibility of building SR 30 as a toll road to accelerate its construction. It was met with mixed reviews from the public and ultimately not approved. The toll feasibility study took six months.<ref>{{Cite web |title=ADOT taking closer look at toll road options in Phoenix area |url=https://www.12news.com/article/news/local/valley/adot-taking-closer-look-at-toll-road-options-in-phoenix-area/75-329025333#aoh=16458327969076&referrer=https%3A%2F%2Fwww.google.com&amp_tf=From%20%251%24s&ampshare=https%3A%2F%2Fwww.12news.com%2Farticle%2Fnews%2Flocal%2Fvalley%2Fadot-taking-closer-look-at-toll-road-options-in-phoenix-area%2F75-329025333 |website=KPNX |access-date=February 26, 2022 |date=October 4, 2016}}</ref> On October 26, 2017, local mayors officially named SR 30 the '''Tres Rios Freeway''' after the nearby Gila, Agua Fria, and Salt rivers.<ref>{{Cite news|url=https://www.abc15.com/news/region-phoenix-metro/central-phoenix/new-proposed-valley-freeway-state-route-30-named-tres-rios-|title=New proposed Valley freeway, State Route 30, named 'Tres Rios' |website=ABC 15 Phoenix |access-date=April 21, 2022 |date=October 26, 2017}}</ref>

In May 2019, the central segment alternative was approved. It was chosen after four years of study comparing four different possible alternatives.<ref name=SR30:L303toL202 />

==Current status== SR 30 is funded by an extension of a regional transportation sales tax that was extended in 2025. That proposed extension was placed on the ballot for Maricopa County voters to vote for in the November 2024 election, known as Proposition 479. With the tax extension approved, funding is provided for all three segments.<ref>{{Cite web |last1=Brown |first1=Ben |title=Prop 479 to extend half-cent sales tax, city leaders warn of 'dire consequences' if initiative fails |url=https://www.abc15.com/news/state/prop-479-to-extend-half-cent-sales-tax-city-leaders-warn-of-dire-consequences-if-initiative-fails |website=ABC 15 Arizona |access-date=August 4, 2024 |date=February 27, 2024}}</ref>

ADOT is currently in the process of acquiring right-of-way for the central segment. In their five-year plan released in March 2022, ADOT has budgeted funds for this purchase.<ref>{{cite web |title=2023-2027 Five-Year Transportation Facilities Construction Program |url=https://azdot.gov/sites/default/files/media/2022/03/23-27%20Tentative%20Book%202-9-22%20%281%29.pdf |website=Arizona Department of Transportation |pages=184 |access-date=April 21, 2022 |date=March 18, 2022}}</ref>

Construction of the central segment will not be until 2027, starting with a {{convert|4.5|mi|km|sing=on}} segment from Loop 202 to 97th Avenue.<ref name="active">{{Cite web |title=State Route 30: Active Projects |website=Arizona Department of Transportation |url=https://azdot.gov/projects/central-district-projects/state-route-30-active-projects#section-2}}</ref> The full central segment is expected to be completed in 2035, with construction of the eastern segment following.

In yearly reports of the Freeway Lifecycle Program (FLCP), full detailed budget timelines of the SR-30 project are shown, they often change from year-to-year, and are not considered official until announced on the ADOT website. As of the 2026 Fiscal Year FLCP report, preliminary timelines show the section from 97th Avenue to Dysart Road starting construction in 2029, Dysart Road to Estrella Parkway starting in 2031, and Estrella Parkway to Loop 303 and MC-85 starting in 2033, matching up with a central segment completion in 2035.<ref name="26 FLCP">{{Cite web |title=FY 2026 Prop 479 FLCP: Program Overview |website=Maricopa Association of Governments" |url=https://azmag.gov/portals/0/Transportation/FLCP/2025/FY-2026-FLCP-Overview.pdf}}</ref>

Also in the FY FLCP Report, the full eastern segment from Loop 202 to I-17 is listed as one project, with a construction date of 2045. Preliminary "interim freeway improvements" to the western segment from Loop 303 to SR 85 is also listed as one project with a date of 2045.<ref name="26 FLCP" /> However, it is likely that the western and eastern segment projects are just placeholders, to comply with state legislation requiring that the project be worked on by 2045.

When SR 30 is first constructed, there will be three lanes in each direction. The ultimate configuration allows for four lanes and one high-occupancy vehicle lane (HOV) in each direction.<ref name=ADOTDesignReport />
