Florida Department of Transportation (FDOT) crews at the Interstate 4 (I-4) and Sand Lake Road (State Road (S.R.) 482) interchange project continue to construct new bridges as part of the overall effort to improve efficiency and capacity at the interchange.

Recently, crews completed deck pours on two of the new bridges. The first deck pour, which occurred in December 2024, took place at the new westbound I-4 entrance ramp bridge from Sand Lake Road. Overnight, crews poured more than 340 cubic yards of concrete across this structure to complete the new bridge deck. In January, this new I-4 entrance ramp was opened to the public.

Additionally, in January, crews conducted two more deck pours for a new bridge over Sand Lake Road alongside westbound I-4. Over two separate nights, crews poured more than 640 cubic yards of concrete across this new bridge, which will eventually form part of the general use lanes of westbound I-4 over Sand Lake Road. The existing bridge for the I-4 general use lanes over Sand Lake Road will be reconstructed to accommodate the expansion of I-4 Express.

Once completed, the expansion of I-4 Express will feature two barrier-separated westbound express lanes from its current endpoint at Kirkman Road (S.R. 435) to just west of Sand Lake Road. The two barrier-separated lanes will then transition to a single, buffer-separated westbound express lane. The completed express lane will be constructed over the course of three separate projects extending from west of Sand Lake Road to west of S.R. 536.

Deck pours are a key step in bridge construction, as these concrete bridge decks serve as the base layer for the driving surface and contribute to the overall structural integrity of the bridges themselves.

FDOT video crews captured the overnight pours at both bridges. Click here to view the video.

Completion of the I-4 and Sand Lake Road interchange improvement project is expected in 2027. For more information on improvements at I-4 and Sand Lake Road, visit i4beyond.com/sandlake. If this area is part of your daily commute, you can sign up for construction alerts here.
