If you own property along Washington Street in Indianapolis, you are living next to one of the largest infrastructure projects in the city's recent history. IndyGo broke ground on the Blue Line bus rapid transit project in early 2025, and construction is now underway along the corridor, with the line expected to open in 2028.
Transit projects of this scale do two things to nearby property tax bills, and they pull in opposite directions. During construction, torn-up streets and restricted access can depress what commercial parcels actually earn. After completion, a permanent transit investment tends to lift land values and invite redevelopment — which eventually shows up on assessments. Corridor owners need to understand both phases, because each one creates a different set of things to check on the next Form 11.
The Project by the Numbers
The Blue Line runs roughly 24 miles between the Indianapolis International Airport and Cumberland, primarily along Washington Street, operating on I-70 between the airport and Holt Road. It replaces the existing Route 8 and, per IndyGo, will connect about 114,000 jobs and 45,000 residents with 60-foot articulated hybrid-electric buses running in dedicated lanes along the majority of Washington Street.
The current $387 million estimate is funded through a mix of federal and local sources, including a $150 million FTA Small Starts Grant, a $21.8 million RAISE grant, and a $135 million local match, plus contributions from the Indianapolis Department of Public Works and Citizens Energy Group.
Crucially for property owners, this is not just a bus project. It is a full reconstruction of the street environment:
| Corridor improvement | Scale |
|---|---|
| New or replaced sidewalks | 7 miles |
| Roadway resurfacing | 5 lane-miles |
| New or refreshed crosswalks | 3 miles |
| New or upgraded ADA curb ramps | 359 |
| Separated storm sewer trunkline | 5 miles |
| New or upgraded traffic signals | 63 |
Sidewalks, drainage, signals, and repaved street frontage are exactly the kinds of public improvements that assessors and appraisers treat as enhancing the desirability — and eventually the value — of adjacent land.
A Corridor Built for Redevelopment
The reason planners fought for the Blue Line for a decade is the same reason assessments along Washington Street deserve close attention: much of the corridor is underbuilt relative to what a rapid-transit street can support.
An analysis published by the Congress for the New Urbanism's Midwest chapter found that within a half mile of the Blue Line route, 16% of properties are either financially upside-down or vacant, and another 35% are low-rise, single-story structures. Only the remaining 48% are more than one story or in civic use.
That is a redevelopment signal. When more than half the parcels near a $387 million transit investment are vacant, distressed, or single-story, the long-run pressure is toward denser uses — and toward higher land values even where the buildings on top do not change. Indianapolis has already seen how quickly land-value repricing can move assessments; our breakdown of Marion County neighborhood land value changes and how to appeal them covers the mechanics.
Note
Indiana assesses land and improvements separately. A transit corridor can push your land value up on the theory of "highest and best use" even while your building — a single-story retail strip, say — earns exactly what it earned before. That gap between theoretical land value and actual income is a recurring appeal issue on corridors like this one.
The Red Line, IndyGo's first BRT corridor, prompted the Indianapolis MPO to commission a formal Transit Impact Study tracking investment and land-use change around its 28 station areas, and IndyGo's own project materials note that proximity to rapid transit is generally associated with higher nearby property values. Quantifying that effect for the Blue Line is premature — the line has not opened — but the direction of the pressure is not in doubt.
Phase One: Construction-Period Impacts (2025–2028)
Before any value uplift arrives, corridor businesses have to survive the construction. Lane restrictions, utility relocation, and torn-up frontage along a 24-mile route are a multi-year reality, with early work concentrated downtown and on the far-east segment.
For commercial owners, this matters at appeal time because Indiana values property as of the January 1 assessment date, and market value reflects conditions as they actually exist — including impaired access and depressed income during construction.
Warning
If your Washington Street commercial parcel lost customer access, parking, or visibility to construction during 2025 or 2026, and your assessment did not move — or went up — you have a factual basis to challenge it. Document the disruption: dated photos of closed curb cuts and torn-up frontage, income statements showing revenue decline, vacancy that coincides with the work. An assessment that ignores a real, income-suppressing condition on the assessment date is contestable.
The strongest version of this argument for income-producing property is the income approach: show what the property actually earned during the disruption versus what the assessment implies it should earn. Temporary conditions do not entitle you to a permanent reduction, but they are legitimate evidence for the years in which they existed.
Phase Two: What to Watch on Future Form 11s
Once the disruption ends and the line opens, watch for the opposite problem — assessments that run ahead of what your specific parcel is worth. Here is the checklist for corridor owners reviewing the Form 11 notices Marion County mails each cycle:
- Land value line, not just the total. Corridor repricing usually arrives through land base rates and neighborhood factors. Compare your land value year over year, separately from improvements.
- Neighborhood factor changes. If your neighborhood code's factor jumps, ask the assessor's office what sales drove it — and whether those sales were redevelopment plays (buyers paying for land) rather than comparables for your use.
- New construction next door. Transit corridors attract new projects, and new buildings enter the rolls at values that can drag trending upward for everyone nearby. Our guide to how new construction is assessed in Marion County explains the timing.
- Use reclassification. Redevelopment interest can tempt an office to reclassify property toward a more valuable use before the market actually supports it. Downtown has seen a version of this dynamic play out with office-to-apartment conversions and their assessments.
- The 45-day appeal clock. A Form 11 starts your window. A corridor-driven jump you disagree with does you no good discovered in month three.
Tip
Keep a simple corridor file starting now: photos of your frontage each quarter, your rent roll or revenue by month, and each year's Form 11. When the post-opening reassessments arrive, owners with a documented before-and-after record will be in a far stronger position than owners reconstructing it from memory.
How AribaTax Helps Corridor Owners
The Blue Line will reprice Washington Street — the only question is whether your assessment tracks your parcel's real value or overshoots it in either phase.
AribaTax tracks parcel-level assessed values, land/improvement splits, and sales across Marion County, so you can see exactly how your corridor is trending before the assessor's number lands. Start with our Marion County property explorer to pull your parcel, use the property lookup tool to compare against neighbors along the corridor, and if the numbers do not hold up, our tax appeal service assembles the evidence and files on your behalf.
