LEE COUNTY, Fl. - A construction zone along interstate-75 becomes the scene of yet another serious crash.  For the second night in a row, a second semi jack knifed near the Palm Beach Boulevard exit.

Troopers say the driver of a tractor trailer was heading northbound.  He lost control and struck several road barriers, causing those to cross into the southbound lanes.  That's when another driver slammed on his brakes to try and avoid the barriers.  They hit his truck... he says he's thankful to walk away unharmed.

"When I see it it's a big surprise for me... there's a big chunk of concrete in front that stopped my truck right there... I say thank you to my God," he says.

"A lot of it has to do with the rain and how people drive and people have to slow down when its raining, a lot of that oil comes to the surface of the road and people just need to slow down a bit and be a little more careful," says Captain Chris Rennie with Tice Fire and Rescue.

The tractor trailer jack knifed but both drivers walked away unharmed.  Just Monday night, this same stretch of 75 was shut down southbound after a massive car crash sent three people to the hospital.

Troopers say since the construction here started, the accidents have increased causing them to beef up their presence.  Debbie Tower with the Department of Transportation says something needs to be done.

"We had over the last month or so been talking about what changes we would to do we had talked about lowering the speed limit that's something we will be doing," she says.

FDOT would change the speed limit from 70 to 60 miles per hour between Luckett Road and Palm Beach Blvd while construction is happening.
