F-DOT and construction crews are putting the final touches on the I-4/Selmon Expressway Connector, set to open in January.
The one-mile stretch of road project has been under construction since 2010 and is finally nearing it's completion.
Crews are putting signs up, a toll gantry is in place and it's all ringing in at a cost of $421 million.
The connector is expected to handle 20,000 cars a day for commuters that would connect between the two highways.
"It's probably one of the largest and most complex projects done in this district," said DOT spokesperson John McShaffrey.
The project consists of several flyovers and bridges.
It was initially conceptualized in a grand master plan for Tampa Bay Highways back in the 1980s according to FDOT, but recent growth has spurred its necessity.
Relieving Ybor City surface streets from Port of Tampa truck traffic was a big part of the eventual equation.
"It's going to be great for 21st and 22nd Streets in particular. The trucks will want to use this route because it's going to save them time and money," said DOT spokesperson John McShaffrey.
Fares for most cars will range between $.25 and $1.25, while most Port of Tampa trucks will pay around $1.
Cash will not be accepted on the I-4 Connector according to the DOT.
"It will be billed by Sunpass or Toll-By-Plate, but we really encourage people to get the Sunpass, because that's the best and quickest way," John McShaffrey said.
