The last stretch of westbound Interstate 4 (I-4) in Seminole County is shifting into final alignment, marking a major milestone for Florida Department of Transportation’s (FDOT) I-4 Ultimate project.
As soon as Thursday, July 9, nearly three and a half miles of westbound Interstate 4 (I-4) between the E.E. Williamson overpass and just west of the Central Parkway overpass, will be in its permanent configuration.
Westbound I-4 motorists will travel brand new lanes extending from west of the State Road (S.R.) 434 interchange all the way to east of the Maitland Boulevard Interchange – more than eight contiguous miles of general use lanes in their final footprint.
To complete the shift, westbound I-4 entrance ramps from S.R. 434 and the westbound I-4 exit ramp to S.R. 434 will close for one night Wednesday, July 8, from 10 p.m. to 6 a.m. the following morning. Please view the detour and shift information here.
The S.R. 434 interchange is also nearing completion after several improvements have been made to improve traffic flow. One of the most notable improvements to the interchange was in April when a new westbound I-4 entrance loop ramp from westbound S.R. 434 opened. The new ramp allows drivers to enter I-4 without a traffic signal, improving flow on S.R. 434. Lastly, the westbound I-4 entrance ramp from eastbound S.R. 434 moved to its final footprint in May. As of now, each ramp at the interchange is in its final alignment. Please download a map of all the improvements to the S.R. 434 interchange.
As closures and detours continue, it is important for motorists to pay extra attention to signage as familiar routes may have changed. Drivers should avoid distractions, adjust their speed, and allow plenty of extra time to navigate the I-4 Ultimate work zone.
Modifications or extensions to these schedules may become necessary due to weather delays or other unforeseen conditions. Motorists are encouraged to follow @I4Ultimate on Twitter or visit I4Ultimate.com for updates.
