About this Project
The Florida Department of Transportation's contractor constructed new northbound exit ramps to State Road 56 from both I-75 and I-275. The I-275 northbound lanes were also realigned within the I-75/I-275 interchange.

Northbound I-75 was widened and resurfaced from the I-275 interchange to SR 56.

Two bridges were constructed: A new northbound I-275 exit ramp to SR 56 crosses over I-75 and a bridge has been built across Cypress Creek for northbound I-75 traffic exiting to SR 56.

The new northbound I-75 and I-275 exit ramps to State Road 56 (Exit 275) opened to traffic on August 16, 2011. It is important to note that the new exit points are about two miles before the previous exit ramp locations.

The first opportunity for drivers to exit I-75 if they miss the new exits is 4 miles north at State Road 54/County Road 54 (Exit 279).

Improvement Highlights

• Traffic exiting northbound I-275 or I-75 to SR 56 is now separated from mainline traffic to eliminate the need for lane changes.
• Better drainage and lighting in this area.

Traffic Flow
The construction phasing was designed so that all existing lanes of traffic were maintained on I-75, I-275 and the ramps during peak traffic hours.

Night Work
In order to maintain the construction schedule and to minimize the impact to the public, it was necessary for the contractor to also work at night. Lane closures, traffic shifts, and traffic paces were used during different phases of the project.

Lane Closure Hours
9 p.m. to 5 a.m.

Traffic Pacing Hours
1 a.m. to 4 a.m.
