1 Adding an acceleration lane on eastbound I-4 from Colonial Drive to Princeton Street improves the capacity of the I-4 general use lanes.
2 The entrance ramp from Colonial Drive to eastbound I-4 now occurs north of Colonial Drive.
3 Reconfiguring the entrance ramp from Garland Avenue north of Amelia Street to eastbound I-4 allows traffic to fly over the Colonial Drive interchange with direct access to eastbound I-4.
4 An eastbound exit ramp off of I-4 will allow direct access to turn left onto Colonial Drive.
5 Adding an entrance ramp from Hughey Avenue to westbound I-4 at Colonial Drive improves access to I-4.
6 Reconfiguring the interchange as a single-point urban interchange (SPUI) under I-4 allows all left-hand traffic movements to be controlled by a single traffic signal. Lanes on Colonial Drive will be wider (11-foot).


Recognizing the importance of Colonial Drive (State Road 50) to motorists, residents and businesses, the Florida Department of Transportation (FDOT) is completely rebuilding the interchange of Colonial Drive and Interstate 4 (I-4) in downtown Orlando.

The change will be dramatic and will include I-4 entrance and exit ramps, as well as a complete makeover of the Colonial Drive intersection near and directly under the I-4 bridge.

The redesign is part of the I-4 Ultimate project, which is reconstructing a 21-mile segment of I-4 to increase safety and mobility throughout Central Florida. When completed, the Colonial Drive interchange will look significantly different. But the new configuration will allow for a more efficient flow of traffic on to and off I-4, along the new highway lanes, and on Colonial Drive.

One of the major changes will involve removing the looping ramps from westbound Colonial Drive to westbound I-4 and from eastbound Colonial Drive to eastbound I-4. They will be replaced with simpler, straighter ramps.

The rebuilding of the interchange involves many significant changes that may seem complicated, but they will create a more efficient interchange, as the accompanying maps and renderings show.

On the westbound side of I-4:

  • Entrance ramp at Hughey Avenue will be added to westbound I-4.
  • A new frontage road between Ivanhoe Boulevard and Colonial Drive will allow westbound I-4 motorists to exit onto Colonial Drive.

On the eastbound side:

  • An eastbound I-4 exit ramp will allow direct access to turn left onto Colonial Drive.
  • The eastbound I-4 entrance ramp from Garland Avenue will fly over the Colonial Drive interchange. That will allow motorists to enter on the right instead of the left.
  • The eastbound I-4 entrance ramp from Colonial Drive will move slightly north of Colonial Drive.
  • A new acceleration lane from Colonial Drive to Princeton Street will allow more time to merge into the general use lanes.

There will be large-scale changes on Colonial Drive beneath the I-4 bridge, which will be remade into a single-point urban interchange (SPUI).

A SPUI is a type of interchange that is used to move large traffic volumes safely and efficiently through an intersection with limited amount of space. A SPUI allows opposing left turns to proceed simultaneously in one single intersection, which is over or under the free-flowing road. The name “single-point” refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals.
