The Sava River Bridge project was honored with the 2017 International Road Federation (IRF) Global Road Achievement Award (GRAA) for program management.The IRF’s annual GRAA program honors one recipient in each of twelve categories.
The Serbian capital of Belgrade is home to 1.7 million people and has experienced significant population growth in recent decades. Belgrade’s population growth has mostly occurred in an area known as New Belgrade, located across the Sava River. This expansion has caused existing transportation links to operate at or above capacity, causing serious traffic congestion and delays.
Louis Berger was selected to provide project management and engineering services for construction of the Ada Bridge across the Sava River, the first major bridge built in the City of Belgrade in 40 years, along with interchanges and approaches. The 964-meter-long, cable-stayed bridge has a single 200-meter-high pylon opened in the center to accommodate twin light rail tracks, making it the world’s widest asymmetrical single-pylon cable-stayed bridge. Using only one pylon to support the main span limits disruption of commercial boat traffic on the Sava River below.
The dramatic structure serves as a city landmark and vital link connecting old Belgrade with the city’s new commercial and residential zones north of the Sava River. By diverting traffic from the city center, the bridge enables significant reductions in traffic congestion of up to 30 percent on existing Sava River bridges. Travel times from the city center to New Belgrade have been reduced by up to 30 minutes.
Applications for the IRF’s Global Road Achievement Awards are evaluated based on a number of criteria including innovative use of existing and new technologies, cost and efficiency considerations, complexity and technical value to the road development industry. The award program is designed to highlight people and projects that place the road industry at the vanguard of global social and economic development.
