H&H was contracted to design key refurbishments to Tower Bridge in London. The bascule bridge is 244 meters long and 61 meters wide, and it accommodates vehicle, cyclist, and pedestrian crossings. It was originally operated by hydraulic power, harnessing steam to power the engines. In 1976, Tower Bridge was converted to a hydroelectric system. The bridge was designed by Sir Horace Jones and opened to the public in 1894. The hydraulic system was first designed by William Armstrong, a prominent English engineer and industrialist.
Tower Bridge is one of the most notable structures in the world, and H&H is helping to strengthen its integrity for the City of London. The scope of work includes designing new walkways, railings, lighting, and drainage to enhance safety and maintenance access. H&H analyzed the bridge’s movements and identified improvements for clearances beneath the deck.
H&H is making structural improvements while respecting the architectural design and heritage designation. Team members on this project include Knight Architects and Alan Baxter Ltd., EMMAUS Consulting, PIB Risk Management, and Watts Group Limited.
