Walo repairs important bridge in the USA

Dietikon ZH/New Castle, July 2023

Walo Bertschinger is repairing the Delaware Memorial Bridge in the USA. The bridge's roadway is being rehabilitated with ultra-high-strength concrete. The double bridge was designed by the Swiss engineer Othmar Ammann after the World War.

Dietiker-based construction company Walo Bertschinger is rehabilitating one of the most important bridges in the eastern United States. According to an announcement on Facebook, Walo is rehabilitating the roadways of the twin Delaware Memorial Bridge over the Delaware River with its ultra-high strength and fibre-reinforced concrete (UHPC). It is the largest application of its kind in North America to date, extending the life of the bridge by decades, Walo’s announcement says. Three-quarters of the surface was completed in time for the summer break, it said. The final phase will be tackled in the autumn and completed in December.

In its statement, Walo recalls that the bridge between the states of New Jersey and Delaware was designed 71 years ago by Swiss engineer Othmar Ammann. The bridge builder also designed and built the George Washington Bridge in New York City. The suspension bridge over the Hudson River connects Manhattan with New Jersey.

The Delaware Memorial Bridge, currently being repaired by Walo Bertschinger, bears its name “Memorial” in memory of the fallen from World War II, the Korean War, the Vietnam War and Operation Desert Storm to liberate Kuwait after its occupation by Iraq.

The Delaware Memorial Bridge connects Pennsville in New Jersey and New Castle in Delaware. On the website of the operating company Delaware River and Bay Authority in New Castle, the double bridge with a length of more than 3 kilometres is described as an important link in the transport system for the entire eastern United States.
