The recent plans for the Colonial Overpass Project have revealed plans to expand Colonial Drive, in a project that we’ve seen referred to repeatedly in City documents as “Ultimate Colonial.”
Colonial Drive is currently composed of primarily five 10-foot lanes as it passes through the downtown core. As it gets closer to the interstate, it become six to seven lanes instead.
The Ultimate I-4 project is going to convert the portion of Colonial that intersects with the interstate into an interchange more like the one at Colonial and Semoran with an extra left-turn lane, and an expansion of one more foot per additional lane. In other words, Colonial Drive is going to be slightly widened as it goes under I-4.
