The $82 million project includes widening and reconstructing 4.5 miles of SR 40 from a 2-lane rural to a 4-lane rural divided facility. The project is located in an environmentally-sensitive area, designated as a “National Scenic Highway” and a “Florida Black Bear Scenic Byway”. The project includes the design of twin 2,711’ bridges over the Ocklawaha River, twin 130’ bridges over Half Mile Creek, and two twin 50’ wildlife crossing bridges.
Ocklawaha River bridge consists of two prestressed concrete bridges. The project requires the construction of parallel, twin bridges that will carry two lanes of traffic in each direction. Each of the twin bridges is comprised of 20 spans. Total bridge length is 2,711’ with steel H-pile supported foundations. Typical spans measure 140’ on the tangent alignment and 139’ on the curved alignment. The superstructure is comprised of 72’ deep Florida-I Beams (FIBs) with a composite cast-in-place concrete deck.
Half Mile Creek bridge consists of two prestressed concrete bridges. Each bridge has two spans of 65’ for an overall length of 130’ and a deck width of 36’ 1”. The superstructures are supported by pile bents composed of 18” square concrete piles.
FINLEY is the Engineer of Record who provided bridge design, load ratings, and temporary critical wall design.
