The I4 project between SR343 and Kirkman has not started yet. There is a large road widening between Daytona and Deland, exit 118. That is not too bad as there is still 2 lanes each way.
Check i4ultimate.com for updates on the Orlando part of the project.
Traffic is like always. Don't be on I4 between 7-9a and 3-6p from SR436 to the FL Turnpike if you can help it. Use SR417 or SR429 depending on from where you are coming from during rush hour times.
