Deputies said the roads reopened around 4:30 p.m. ET but that drivers should "expect continued disruptions in and out of the Florida Keys as the weather/fire mitigation efforts continue to impact traffic."
The highway was shut down for hours Tuesday afternoon and evening as smoke and nearly flames dropped visibilities to dangerously low levels. The road was eventually reopened around 8:30 p.m. Tuesday before shutting down again around 4 p.m. Wednesday.
The blaze has burned about 4,000 acres and is just 20% contained, according to the Florida Forestry Service.
