SR 417/South Access Road/Boggy Creek Road Interchange

Improved Interchange Enhances Airport Access

Orlando, Florida

The design included three precast, post-tensioned curved concrete U-beam bridges, the first of their kind in Florida, and a curved steel bridge.

The post-tensioned precast curved concrete U-beam bridge design reduced initial construction costs and anticipated future maintenance needs.

The first of their kind in Florida, the beams were precast, erected, and temporarily supported as lid slabs were placed.

Once lid slabs were placed, the beams were post-tensioned to increase torsional resistance and splices were closure poured together.

One of the four bridges was designed with steel materials due to span lengths that exceeded standard concrete U-beam bridge capacity.

Substructure designs took into account a multifaceted site, which included an existing stormwater pond and creek.

The new roadway design eases bottlenecking during peak traffic periods that was once caused by airport traffic being forced through two major access roads.

The ribbon cutting ceremony featured representatives from the Central Florida Expressway Authority, Greater Orlando Aviation Authority, and commissioners from Lake, Orange, and Osceola counties.

With more than 800 flights daily, the Orlando International Airport serves upwards of 35,000,000 passengers annually. The vast majority of passengers access this second largest Florida airport by car or bus, causing severe congestion for commuters and passengers alike.

We designed a four-level interchange with flyover ramps that connects the adjacent high speed limited access highway to the airport's access road. This will alleviate the congestion where airport traffic normally meets local traffic, and provide an easy access to and from the airport. Three of the bridges were designed as post tensioned curved concrete U-beam bridges, the first of its kind in Florida.
