“8664” proposal to remove part of I-64 through Louisville’s Waterfront Park resurfaces, renewing debate

A renewed push to remove the Interstate 64 stretch that runs through Louisville’s Waterfront Park area is resurfacing as local advocates revive the long-running “8664” proposal, WLKY reported on Aug. 14, 2026. The effort, described by proponents as a way to reshape the downtown riverfront corridor, would involve taking down part of the interstate where it cuts through the park setting.

The plan draws on a history of similar proposals that have circulated for decades, with supporters arguing that the current highway layout separates neighborhoods and limits how the waterfront can be used by families, visitors, and businesses. The resurgence follows the return of public discussions about whether the downtown interstate segment should be reduced, replaced, or removed.

WLKY reported that the renewed calls are being made as part of a broader conversation about how the city manages its transportation network in the downtown core and how it balances highway capacity with pedestrian and community space. Proponents of “8664” characterize the interstate stretch as an impediment to waterfront development and access, while opponents and transportation officials, where they have spoken previously in similar debates, have typically pointed to the role of I-64 in moving traffic through the region.

While the new round of attention has reopened the question for public officials and residents, WLKY’s report framed the “8664” effort primarily as a call to revisit the feasibility of removing the roadway segment rather than as a finalized project with an announced timeline or funding plan. Any change to a major interstate would require coordination among state and federal transportation authorities and would likely involve extensive planning, environmental review, and engineering work.

Transportation infrastructure changes of this scale also raise public-safety and traffic-management questions. Removing or rerouting interstate lanes in a concentrated downtown area would require a redesign of access points, bridges, interchanges, and detours to maintain emergency routes and regular traffic flow. Those practical considerations are at the center of most debates over downtown highway removal projects, particularly when the infrastructure is integrated into regional commuting patterns.

For Louisville, the controversy also touches local land use and the future use of the riverfront. Waterfront Park is a community destination and event venue, and advocates of “8664” argue that a redesigned corridor could better support public space. Even so, city and state decision-makers would likely need to weigh short-term disruptions against long-term outcomes if the proposal moved from discussion to formal planning.

WLKY reported the “8664” debate as part of a renewed push to tear down the interstate stretch through the Waterfront Park area. The immediate next step, as reflected in the report, is continued public engagement and attention to whether the proposal will receive formal consideration through the city’s transportation planning process.

As the discussion develops, residents may see further meetings, presentations, and commentary from local officials, transportation agencies, and affected stakeholders. Until any responsible agency endorses a specific alternative and publishes a schedule, details of scope, costs, and how traffic and access would be handled remain the subject of ongoing public debate rather than confirmed project plans.
