SR 836 / I-395 / I-95 Reconstruction Design-Build Structures

Ardurra serves as Engineer of Record for nine bridges (seven permanent, two temporary), including the eastbound and westbound SR 836 bridges over I-95, for the comprehensive I-395/SR 836/I-95 Design-Build Project. This major reconstruction initiative enhances capacity and safety across three critical Miami-Dade highways through advanced multi-level structural design featuring 3rd and 4th-level structures with specialized Category 2 substructure elements.

The complex bridge portfolio incorporates sophisticated engineering solutions, including straddle piers, augercast foundations, and structural elements specifically designed for construction loads from beam launchers used during beam placement operations. Additional bridge work includes widening existing steel plate girder structures and installing prestressed concrete beams throughout the corridor.
