Small sinkhole prompts emergency road closure of section of Southwest 24th Avenue in Gainesville
Key facts
- Minor sinkhole opened Nov. 12, 2025 on Southwest 24th Avenue near the roundabout at SW 91st Street in Gainesville.
- Road closed in both directions between SW 91st Street and SW 87th Way; detours and signed traffic control in place.
- Hole measured roughly 2 feet across at the surface and about 25 feet deep below the pavement in places; described by county as a “chimney.”
- Alachua County Public Works carried out safety repairs immediately and expected to reopen the road within a day with permanent repairs to follow.
Incident summary
On Nov. 12, 2025, a small sinkhole was discovered on Southwest 24th Avenue just east of the SW 91st Street roundabout. Witnesses and county crews described the opening as roughly two feet wide at the surface with voids extending five to six feet across in the underlying soil and an estimated depth approaching 25 feet. That geometry matches a classic chimney type collapse where surface material funnels into an underground void. The county marked the site with cones and stakes and moved quickly to close the affected segment of roadway between SW 91st Street and SW 87th Way.
The practical consequence was immediate: both directions of Southwest 24th Avenue were shut for public safety and detour signs directed traffic around the closure. Sidewalks in the immediate area remained open. Alachua County Public Works characterized the feature as routine for the area and set expectations that short term safety repairs could allow reopening within a day, while permanent stabilization would occur later. The combination of visible depth and narrowing near the surface explained the decision to restrict vehicle access without delay.

Response, traffic and community impact
The county response blended urgency with pragmatism. Alachua County Public Works, led on scene by the construction inspection team, installed detour signage and limited egress for some neighborhood exits. For residents of the Shannon Woods subdivision, for example, exiting via SW 88th Street meant restricted directional choices until repairs were underway. Public messaging focused on standard safety counsel: follow posted detours, expect delays and maintain safe speeds through alternate routes.
From a public administration perspective, the cascade is predictable but instructive. A small physical failure exposed dependencies in local circulation and highlighted the tradeoffs between immediate safety measures and longer term repair logistics. Short term measures lean on channeling traffic, protection of vulnerable pavement edges and shoring up the hole to prevent incremental enlargement. Local officials set lines of communication via social media and press releases and provided a phone contact for further inquiries. That mix aims to minimize disruption while the assessment and remediation plans are finalized.
For commuters the practical implication was simple. Drivers were routed around the closure and told to allow extra travel time. For county agencies the incident was an operational matter requiring inspection, a temporary safety repair and scheduling for permanent stabilization work. For residents it was a reminder of how quickly localized ground failure can interrupt daily life. Further details and official contacts appear in the county announcement and local coverage: Mainstreet Daily News and Gainesville Sun.
Technical context and local geology
The sinkhole was described by county staff as a chimney. That term signals a particular collapse mode: subsurface material erodes or is removed from below and the overlying soil collapses into a relatively narrow vertical conduit. In Florida, where karst terrain is widespread, such collapses are not unusual. The state’s subterranean landscape includes soluble limestone and variable soil cover. Water movement through the bedrock dissolves channels and cavities over time. When those voids intersect the ground surface and remove support beneath pavements or structures, the result can be a sudden surface expression like the one on SW 24th Avenue.
Understanding that context matters for response and for public expectations. A chimney type opening can appear small at the surface but be disproportionately deep and unstable below. Engineers therefore err on the side of containment and detours until geotechnical assessment is completed. Permanent repair typically involves cleaning and filling the void, compacting new subgrade and repaving. In some cases more extensive underpinning or grout injection is required to address ongoing subsurface instability. Officials told reporters they expected to complete safety repairs quickly and schedule more lasting work afterward. For readers interested in the wider policy angles, the incident also joins broader conversations in Florida about groundwater, drainage management and land use that influence the frequency of such events.

Practical advice and what to watch next
Officials encouraged drivers to heed detours and to allow additional travel time while repairs are underway. For pedestrians the sidewalks remained open at the time of reporting but officials recommended caution near the closure and adherence to temporary barriers. The county provided a phone contact for further information and planned to update the public as repairs progressed. When permanent repairs are scheduled, expect intermittent lane closures and construction staging that may extend the period of localized disruption.
From a reporting perspective, the next items to monitor are simple and consequential. First, when Alachua County confirms a reopening date in the days following the incident. Second, details on the permanent repair approach and schedule. Third, any assessments that point to broader vulnerabilities in the immediate corridor or nearby neighborhoods. Taken together those updates will tell whether this sinkhole is an isolated infrastructure hiccup or a signpost of systemic subsurface conditions that merit longer term planning and investment.
