Weidlinger’s innovations in bridge engineering result in part from experience in analyzing the problems of century-old structures and designing their reconstruction to correct original defects and diminish future fatigue and cracking. State and city transportation authorities rely on Weidlinger to monitor, upgrade, and design their long spans--suspension, truss, cable-stayed, and concrete segmental—and their highway bridges. In searching for the best design solution, our bridge engineers pay close attention to time and budget constraints, constructibility, and traffic maintenance.
Design of new bridges and R&D are as important to Weidlinger's practice as rehabilitation. Recently, Weidlinger engineers designed major structural elements of a new self-anchored suspended span for the San Francisco-Oakland Bay Bridge to withstand an 8.0-magnitude earthquake. Our engineers also designed a replacement deck for the Bronx-Whitestone Bridge and improved its aerodynamic stability with the addition of wind fairings, the largest application of FRP composite panels on a bridge to date. A third recent milestone was authorship of the first-ever guidelines for the inspection and evaluation of suspension bridge cables.
