If you’re sitting in park on the asphalt right now or frantically checking your GPS before heading out, you've probably realized things are a mess. Getting a straight answer on why is I 75 closed in Florida today can be like trying to read a map in a hurricane. Between the massive widening projects in Tampa and the "Alligator Alley" resurfacing down south, the reasons for closures change by the hour.
Honestly, it’s rarely just one thing. On a stretch of highway that runs from the Georgia line all the way to Miami, you’re usually looking at a cocktail of planned construction, sudden crashes, and those "fun" Florida weather events that turn three lanes into a lake.
The Current Construction Squeeze
The Florida Department of Transportation (FDOT) is currently in the middle of a massive overhaul. If you’re near Lee County, specifically between Bonita Beach Road and Alico Road, you’ve likely seen the barricades. They are doing a $22.9 million milling and resurfacing project. While most of the heavy lifting happens at night, the concrete barriers and shifted lanes don't just disappear when the sun comes up.
In the Tampa Bay area, specifically from MLK Jr. Boulevard up to Fowler Avenue, the widening project is a major headache. We're talking about overnight lane closures that often bleed into the early morning hours. If a crew hits a snag with a crane or an overhead sign installation, that "5:00 AM reopening" becomes 7:00 AM real fast. You’ve probably felt that frustration personally.

Why the Northbound Side is Worse Today
In the Naples area (specifically around MM 93), there has been active construction affecting the left shoulder and left lane. This isn't just a "cones out for no reason" situation; they are working on drainage and ITS (Intelligent Transportation Systems) items. When they close a lane in the morning, the ripple effect on traffic can stretch for ten miles.
Then you have the Sarasota-Manatee stretch. They are building new bridges and installing drainage near SR 70. This involves heavy equipment crossing the road. Flagging operations are intermittent, which basically means you might stop for ten minutes while a massive dump truck crawls across the highway.
When It’s Not Construction: The Accident Factor
Florida drivers are... unique. Let’s be real. On any given Saturday like today, January 17, accidents are the #1 reason for "unplanned" closures.

A vehicle crash with injuries was reported early this morning on I-75 Northbound in Broward County near the ramp to Eastbound I-595. Even after the cars are towed, the Florida Highway Patrol (FHP) has to investigate, and if there's a fuel spill, the environmental teams have to scrub the road. You can't just drive over a pool of diesel; it eats the asphalt.
- Jackknifed semis: These are the worst for I-75. One truck goes sideways on Alligator Alley, and the whole state basically stops moving.
- Rubbernecking: Even when a crash is on the shoulder, the "looky-loo" effect slows the opposite side to a crawl.
- Disabled vehicles: On the narrow stretches of the Alley, a simple flat tire can force a lane closure because there’s literally nowhere else for the trooper to park safely.
Alligator Alley and the "Big Gap"
If you're stuck between Naples and Weston, you're on the Alley. This is the most dangerous place to have a closure because there are almost no exits. If why is I 75 closed in Florida today involves a segment of Alligator Alley, you’re basically trapped until they clear it.
The current RRR (Resurfacing, Restoration, and Rehabilitation) projects on the Alley are split into sections. They’re replacing guardrails and fixing the bridge decks. Sometimes, the thermal expansion of the bridge joints in the Florida heat causes "blow-ups" where the pavement actually buckles. When that happens, FDOT has to close the road immediately to prevent cars from launching into the air.

How to Get Around the Mess
Don't just trust the big green signs on the highway. They are often ten minutes behind reality.
- FL511 is your best friend. It’s the official FDOT clearinghouse. Use the app or the website.
- Waze over Google Maps. In Florida, Waze users are aggressive about reporting "police hidden" or "object on road." It’ll give you that 30-second heads-up you need to dive off at the last exit.
- The US-41 Alternative. If I-75 is a parking lot in Southwest Florida, Tamiami Trail (US-41) is your escape valve. It’s slower with the stoplights, but at least you’re moving.
- Avoid the "Rush." On weekends, the 10:00 AM to 2:00 PM window is brutal for I-75 as everyone heads to the coast or the theme parks.
Actionable Steps for Today’s Drive
Before you put the car in gear, check the FHP Live Traffic Map. It shows real-time CAD (Computer Aided Dispatch) notes from the troopers on the scene. If you see "Roadblock" or "Extrication" in the notes, find a different way.
If you are already stuck, stay in your car. People tend to wander out on the highway when traffic stops, but I-75 is notorious for "secondary crashes" where a distracted driver slams into the back of the stopped line. Keep your eyes on the rearview mirror.
Check the local news for the specific county you are in—whether it's Lee, Collier, or Hillsborough—as they often have the most granular details on bridge failures or sudden police activity that the statewide apps might miss.
