Multi-Vehicle Crash Blocks Lane on Lake Mary Blvd at Forest Blvd

A multi-vehicle crash blocked the right westbound lane on Lake Mary Boulevard at Forest Boulevard Thursday morning, hitting one of the most persistently dangerous intersections in Seminole County during peak commute hours.

The right lane remained impassable through the morning commute. No information on the number of vehicles involved, injuries, towing timeline, or whether speed, impairment, or weather were contributing factors had been publicly confirmed as of Thursday morning. The official crash report, once processed, can be requested through the Seminole County Sheriff's Office Public Records Unit via the SCSO's online portal. The Florida Highway Patrol also maintains a live road conditions viewer at trafficincidents.flhsmv.gov.

What we know: the right westbound lane on Lake Mary Boulevard at Forest Boulevard was blocked Thursday morning. What remains unconfirmed: injury status, vehicle count, cause, and when the lane will fully reopen.

For drivers diverting around the blockage, westbound traffic on Lake Mary Boulevard was best rerouted south via Country Club Road to Longwood Lake Mary Road, reconnecting to the I-4 corridor before the Lake Mary Boulevard interchange. Commuters relying on the Greenway/417 northbound connection at International Parkway, roughly one mile east of the crash site, faced the likelihood of secondary queues at the toll plaza as volume from the blocked lane redistributed. The I-4 westbound on-ramp at Lake Mary Boulevard, already a chronic bottleneck during morning rush, was positioned to absorb much of the overflow.

The intersection's role in Thursday's disruption is part of a well-documented pattern. The Seminole County Traffic Engineering 2015 Crash Summary recorded 22 crashes at Lake Mary Boulevard and North Forest Boulevard that year, placing it tied for seventh on the county's official top-10 highest-crash-location list. The same intersection appeared in the county's 2004 top-10 with 17 crashes, accounting for 4 percent of all tracked crashes countywide that year; two of those 17 resulted in driver injuries. The data spans more than two decades without the intersection falling off the list.

That record sits within a county that already carries the worst crash burden in Florida. Seminole County logged 2,369 crashes between January and May 2023, a rate of 199 per 10,000 residents that ranked highest among all Florida counties during that period, nearly double Hamilton County's rate of 104 per 10,000. Florida ranks third nationally for traffic fatalities.

Investments on the corridor have attempted to keep pace with the volume. The Florida Department of Transportation designated Lake Mary Boulevard a high-priority traffic management corridor and deployed connected vehicle technology, including Signal Phase and Timing and Emergency Vehicle Pre-emption systems, at seven signalized intersections between International Parkway and Rinehart Road. As recently as August 2025, a new turning lane opened at Lake Mary Boulevard and Country Club Road to reduce recurring congestion on the route.

Seminole County's Vision Zero Action Plan, published in 2024, commits the county to eliminating traffic deaths and severe injuries on local roads. The sustained crash history at Lake Mary Boulevard and Forest Boulevard is precisely the kind of long-term intersection pattern the plan was built to target.
