Last May we discussed the impending improvements for the Colonial/I-4 interchange, an “Ultimate Colonial.”

Changes will include I-4 entrance and exit ramp overhauls and a complete makeover of the Colonial Drive intersections near and under the I-4 overpass, including:

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.

  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. 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.
  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).
