Few Tucson streets have been torn up as long, or in as many separate pieces, as Grant Road. If you drive midtown, you have watched it inch east for years — cones, lane shifts, fresh medians, then a new stretch of construction a mile down. The end of the current chapter is finally close. The Grant Road Improvement Project is rebuilding roughly five miles of the corridor from Oracle Road east to Swan Road, and the City of Tucson expects the active Phases 3 and 4 — from Alvernon Way to Swan — to wrap in October 2026. Here is the June 30, 2026 New Development read on what's actually being built. ~5 mi — Corridor being rebuilt, Oracle Road to Swan Road. 6 — Travel lanes after the widening, three each direction. ~$56M — Reported construction cost of Phases 3 and 4. Oct 2026 — Target finish for the current Phases 3 and 4 A Five-Mile Rebuild, Decades in the Making Grant Road is one of 35 major roadway corridors Pima County voters approved in 2006 under the 20-year Regional Transportation Authority plan, and the City of Tucson Department of Transportation and Mobility has been delivering it in bite-sized phases ever since. Phase 1 — the indirect-left intersection where Grant meets Oracle Road — was completed in 2013. Phase 2, from Stone Avenue to Park Avenue, opened in 2018. The aim across all of it is the same: take an aging four-lane arterial that tens of thousands of vehicles use daily and turn it into a six-lane, multimodal corridor with room for buses, bikes, and people on foot, not just cars. Doing that a mile or two at a time is slow, but it lets the city acquire right-of-way and relocate utilities one segment ahead of the pavement. What Phases 3 and 4 Add The current work, from Alvernon Way east to Swan Road, broke ground on May 20, 2024, and it is more than extra asphalt. Plans call for six travel lanes, landscaped medians, five-foot bike lanes buffered from traffic, wide ADA-compliant sidewalks, public art, and covered SunTran transit stops with dedicated bus pullouts so stopped buses no longer block a lane. The headline change for drivers is the intersection geometry: Grant and Alvernon is being rebuilt with an indirect-left design, which removes the direct left turn at the crossing and routes those movements differently to keep through-traffic moving. The latest 2026 reporting pegs the Phases 3-4 construction at roughly $56 million, funded through the RTA plan and managed by the city. Phase 1 — Done (2013) (Grant & Oracle, Indirect left, Completed): The westernmost piece, an indirect-left intersection at Grant and Oracle Road, set the template the rest of the corridor follows and reopened in 2013. Phase 2 — Done (2018) (Stone Ave to Park Ave, Six lanes, Completed): The Stone-to-Park segment was widened and finished in 2018, adding the medians, bike lanes, and sidewalks now standard across the project. Phases 3 & 4 — Underway (Alvernon to Swan, Broke ground May 2024, Wrapping Oct 2026): The active stretch, including the rebuilt indirect-left intersection at Grant and Alvernon. This is the work causing the current midtown construction zone, and the segment on track to finish this fall. Phases 5 & 6 — In Design (Campbell to Country Club, Design phase, Pushed to 2029): The middle segment, from Campbell Road to Country Club Road, is in design. A revenue squeeze has pushed its construction start to 2029, so a gap in the corridor will remain after the current phases finish. The Construction-Zone Reality Right Now Until the Phases 3-4 work wraps, the Alvernon-to-Swan stretch stays a live job site, and the biggest day-to-day change is already in effect: drivers can no longer make a direct left turn at Grant and Alvernon under the new indirect-left design, a shift that took some getting used to when it rolled out. Expect ongoing lane restrictions, shifted travel lanes, and periodic driveway and side-street access changes along the segment through 2026. As with any project this size, the schedule and specific closures move, so confirm the current status at grantroad.info before you plan a route through midtown. What It Means If You Live — or Are Buying — Along Grant A finished Grant Road gives midtown a continuous six-lane spine with buffered bike lanes and upgraded sidewalks tying together a wide band of central Tucson — a stretch where a lot of the housing stock is older, more affordable, and close-in. For market context, Homes.com put the median sale price in midtown Tucson near $270,000 over the trailing 12 months as of mid-2026, down about 8% year over year, against a broader Tucson median around $320,000 and a typical Tucson home value near $333,000 per Zillow in the same window. The midtown ZIP codes the corridor threads through include 85712, 85716, and 85719. None of this is investment advice — corridor projects cut both ways, easing congestion and adding walk-and-bike access once finished while bringing noise and detours during construction — but the long-term direction is more capacity and better multimodal connections on a road a lot of central-Tucson buyers and sellers care about. Quick reference (June 30, 2026): The Grant Road Improvement Project is rebuilding ~5 miles from Oracle Road to Swan Road into a six-lane, multimodal corridor under the voter-approved RTA plan, managed by the City of Tucson. Phase 1 (Grant & Oracle) finished 2013 and Phase 2 (Stone to Park) in 2018. The current Phases 3 and 4 (Alvernon Way to Swan Road) broke ground May 20, 2024, are reported at roughly $56 million, and are on track to finish in October 2026, adding landscaped medians, five-foot buffered bike lanes, wide sidewalks, public art, covered SunTran stops, and an indirect-left intersection at Grant and Alvernon. Phases 5 and 6 (Campbell to Country Club) are in design with construction pushed to 2029. Confirm details at grantroad.info before you travel. The Takeaway Grant Road has been a construction zone for so long it's easy to forget what it's becoming: a six-lane, median-divided corridor with buffered bike lanes, wide sidewalks, and real transit stops running across the middle of the city. The current Alvernon-to-Swan phase finishing this fall is the big near-term milestone, even as the Campbell-to-Country Club segment slips to 2029. For anyone living, commuting, or house-hunting in midtown, it's worth knowing both halves of the story — the short-term squeeze and the longer-term payoff of a faster, better-connected route.
