About this Project
The Florida Department of Transportation's contractor widened I-275 from U.S. 41 (Nebraska Avenue -- just north of Bearss Avenue, Exit 53) to just southwest of Interstate 75. This project included adding one lane in each direction -- making that stretch of highway a six-lane roadway (3 in each direction) to match up with the existing six lanes to the south. The new lanes were built in the median.
A concrete barrier was built in the median separating the northbound and southbound lanes within the southern portion of the project. The high tension cable barrier installed in the median in 2007 remains in the northern portion of the corridor.
Drainage was also improved along the corridor through the addition of new ponds and drainage pipes to handle storm water runoff.
The project also added Intelligent Transportation System (ITS) components to the corridor to assist with traffic management. The devices installed included 5 cameras, 20 microwave vehicle detectors, fiber optic cable, and one Dynamic Message Sign to relay important traffic information to drivers.
A traffic control was developed to minimize inconvenience to the traveling public. However, nighttime closures were needed for mainline travel lanes (see hours below).
