The bridge was critical. As the invasion of Normandy began, seizing and holding the La Fière bridge was one of three central objectives for the USAF. This route was essential for movement inland from Utah Beach and to prevent German reinforcements from moving west. It simply couldn’t be done without securing the bridge.
Driving more than 2500 km around New Zealand is an endeavour filled with hazards. But winding roads and falling rocks and monsoon rains are to be expected. It’s the bridges I’m not prepared for. Constructing highways through challenging landscapes has led to bridge designs that are rather shocking by North American standards.
