Train Bridge replaced with help from SF Marina

Built in 1896, the Norwalk River Railroad Bridge in Norwalk, Connecticut, USA, is a frequent single point of failure for the Amtrak and Metro-North commuter trains that traverse its 562' span. Construction to replace the aging infrastructure has begun with SF Marina playing a small but vital role. It's supplying a floating concrete dock for the ferries, tour boats, transients and Norwalk Maritime Aquarium support vessels temporarily displaced by construction equipment.
Jointly installed by Cianbro and Middlesex construction contractors, the 378' dock consists of six SF1230 concrete pontoons. Developed for commercial ports, they have a low center of gravity and exceptional mass that makes them extremely stable. Their unique design attenuates waves, swells and wakes — an important consideration with heavy barges and tugs working in the area. With the heavy-duty non-marking D-fenders, the dock is an ample 3.25m wide. Shore-side external piles and 45cm heavy-duty cleats provide vessels with a straightforward docking area.
The new dual-span vertical-lift bridge will replace an outdated rotating swing design. Construction is expected to be completed in 2029. More information is at www.walkbridgect.com.
