The Quick Answer

Interstate 670 through Downtown Kansas City is scheduled to close in both directions from I-35 to U.S. 71 beginning December 2, 2026, through September 2028.

The closure supports Phase One of Roy Blunt Luminary Park, a proposed public park constructed above the highway to strengthen the pedestrian connection between Downtown and the Crossroads Arts District.

Closures on Truman Road and periodic restrictions on nearby streets will extend the impact beyond the interstate itself. In January 2027, a separate I-70 reconstruction closure will add another significant change to travel across the urban core.

For commercial property owners and tenants, the immediate issue is access. For Kansas City's long-range urban development, the potential benefit is a more connected public realm.

Kansas City I-670 Closure Dates and Streets Affected

The official Luminary Park construction information outlines the highway limits and street-level work. Closures are currently scheduled and may change as construction progresses.

Where to check detours: Property owners, commuters and businesses should monitor the official Luminary Park construction page and the Missouri Department of Transportation for updated project schedules and traffic information.

What Is Roy Blunt Luminary Park?

Roy Blunt Luminary Park is a planned public green space that will cap part of the I-670 corridor on the southern edge of Downtown Kansas City.

The broader concept is intended to reconnect downtown destinations with the Crossroads Arts District across an interstate that has long acted as a physical boundary.

Rather than simply adding landscaped space, the vision is to create a more comfortable pedestrian environment and a public destination between areas that already support significant employment, residential, cultural and commercial activity.

The proposed larger park encompasses approximately 5.5 acres, but the currently funded first phase does not complete the entire park.

What Phase One Actually Builds

Phase One will construct the first park block between Wyandotte Street and Baltimore Avenue near the Kansas City Convention Center.

The project will also include substantial tunnel and highway infrastructure designed to support future sections, including safety, fire-protection and operational systems.

According to KCUR's October 14 reporting , Phase One represents an investment of approximately $164 million.

Funding for the remaining park blocks has not yet been fully secured. The completion of the full proposed park therefore remains dependent on additional funding and approvals.

Two Major Interstate Closures Will Overlap in 2027

The I-670 project is arriving alongside another consequential transportation program: Improve I-70 KC .

MoDOT plans an approximately 11-month shutdown of I-70 between The Paseo and Van Brunt Boulevard beginning January 11, 2027, subject to weather.

Because both projects will occur simultaneously, regional drivers may shift onto neighboring highways and local streets.

The combined disruption makes clear communication especially important for businesses that depend on highway access, deliveries, customer visits and commuting employees.

A property's physical address will not change, but the most practical route to its entrance, parking facility or loading area might.

What the I-670 Closure Means for Downtown Commercial Real Estate

Crossroads Arts District and Southwest Boulevard

Crossroads retailers, galleries, offices, restaurants and mixed-use buildings depend on a combination of destination visitors, nearby residents, employees, deliveries and pedestrian activity.

During construction, properties near the project may require updated visitor directions, more proactive tenant communications and changes to how available commercial space is presented to potential occupants.

For businesses on Southwest Boulevard, the impact will depend on the specific routes customers and suppliers use. Owners should check actual access conditions rather than assuming the entire district will experience identical disruption.

Downtown Kansas City and the Central Business District

Downtown office buildings, hotels, residential towers and entertainment destinations rely on transportation networks that connect visitors, commuters and service providers.

Temporary changes to access could affect parking decisions, visitor travel times and the customer experience.

Owners and property managers should consider whether websites, leasing presentations and visitor instructions need to include additional information about construction.

River Market and the Northern Urban Core

Although River Market properties are located north of the I-670 construction corridor, broader changes to regional travel patterns may still affect how people navigate Downtown.

The magnitude of any impact will depend on the property's location, customer origins and the specific routes used.

This is particularly relevant for commercial properties that depend on regular deliveries, regional customers or employees arriving from outside the downtown area.

Could Luminary Park Increase Downtown Kansas City Property Values?

New parks, streetscape improvements and pedestrian infrastructure can contribute to a neighborhood's appeal.

Public spaces may support activity by making districts easier to navigate, more attractive to visitors and more accessible on foot.

For Downtown Kansas City, the potential benefit of Luminary Park is not limited to the park itself. It also involves improving the relationship between the central business district and the Crossroads Arts District.

Better pedestrian connections could create opportunities for surrounding businesses, residential development and commercial property uses.

However, there is an important distinction between potential neighborhood benefits and measurable financial returns.

A new park does not automatically increase the value of every nearby property.

Investment performance will still depend on acquisition costs, financing, rental income, tenant demand, building condition and broader economic conditions.

The park's remaining phases also depend on future funding. Buyers and developers should avoid treating an uncompleted project as a guaranteed future amenity.

What Kansas City Real Estate Investors Should Consider

Major infrastructure projects can create both temporary operating risks and longer-term development opportunities.

Investors evaluating Downtown Kansas City properties should distinguish between these two periods.

During Construction

• Potential changes in tenant accessibility
• Possible impacts on customer traffic
• Changes to loading and delivery logistics
• Additional property management coordination
• Potentially longer marketing or lease-up periods
• Possible tenant concerns about accessibility

After Phase One Completion

• Potentially improved pedestrian connections
• Additional public gathering space
• Opportunities for nearby businesses
• Changes to the surrounding streetscape
• Potential benefits for walkability and connectivity

These possible outcomes should be evaluated as scenarios, not promises.

For commercial real estate acquisitions, investors should review actual lease terms, tenant business models, parking arrangements and documented property performance.

For redevelopment projects, realistic construction timelines and carrying costs should be included in financial underwriting.

How Downtown Kansas City Property Owners Can Prepare

Preparing for construction before road closures begin can reduce confusion for tenants, customers, buyers and property visitors.

1. Confirm property access. Review entrances, garages, parking facilities and loading areas against official construction notices.
2. Update marketing materials. Revise listing directions, property websites, tenant welcome materials and business arrival instructions.
3. Communicate with tenants. Discuss delivery windows, customer accessibility, signage and potential operational concerns.
4. Monitor property performance. Track inquiries, tours, occupancy and business activity where appropriate. Avoid attributing every change solely to construction.
5. Underwrite multiple scenarios. Model possible carrying costs, slower leasing, tenant incentives and operational disruptions.
6. Coordinate with professional advisers. Review lease provisions with qualified legal counsel and financing assumptions with appropriate lending and real estate professionals.

What Buyers and Sellers Should Consider During Construction

Buyers researching a downtown condo, loft or mixed-use building should understand the property's entrances, parking arrangements and documented construction impacts.

Those questions are particularly relevant if a buyer expects to commute by car or operate a business that depends on regular deliveries.

For sellers, accurate information and practical directions can build credibility with prospective buyers.

Property marketing should not imply that routes will remain unchanged throughout construction or that the completed park will necessarily increase property values.

A compelling listing can describe the area's long-term public investment while remaining transparent about near-term transportation restrictions.

Frequently Asked Questions

The Bigger Picture: A More Connected Kansas City

The near-term consequence of the I-670 closure will be disruption. Downtown businesses and property owners should prepare now rather than treating access as a concern to solve after construction begins.

But the longer-term civic objective is larger than a transportation detour.

Roy Blunt Luminary Park is intended to transform part of a longstanding highway barrier into public space, potentially making the connection between Downtown Kansas City and the Crossroads more inviting for pedestrians.

For Kansas City's real estate market, both realities deserve attention: the operating challenges of construction today and the possible benefits of better urban connectivity tomorrow.

Property-level research, realistic financial planning and transparent communication will be more useful than either predictions of dramatic losses or promises of automatic appreciation.
