Bridge & Structural Engineering

Description of Services

The Bridge & Structural Engineering team at Reliance Engineers delivers industry-leading expertise in the planning, analysis, and design of bridge and structural systems across a wide range of transportation infrastructure projects. Our experience spans the full spectrum of bridge types—from complex, long-span structures such as cable-stayed, arch, segmental, and truss bridges, to short- and medium-span solutions including precast girder, steel plate girder, and box-girder bridges. We provide structural design services for both roadway and railway bridges, incorporating a deep understanding of the unique demands of each sector. Our engineers are highly proficient in the design of reinforced and prestressed concrete, structural steel, and steel-composite systems, and have successfully delivered designs for a variety of fixed and movable spans. We are adept at addressing challenging site geometries, including curved, skewed, and superelevated alignments, as well as projects involving phased construction, staged loading, and complex erection sequencing. Utilizing advanced structural analysis tools and 3D modeling platforms, we develop efficient, resilient designs that meet or exceed the requirements of AASHTO, AREMA, and applicable regional standards. From concept development to final design and construction support, our team combines technical precision with a practical, construction-aware approach—ensuring that every solution we deliver is not only structurally sound, but also optimized for constructability, cost-effectiveness, and long-term performance.
