>>1944291>>1944326Old bridge was opened in 1957, which is peak socialism era in Norway. It's also downstream which may have been a contributing factor.
>>1944736There's now talk of reinstating the old bridge to rail duty. If the loading guage fits, it's maybe able to carry today's axle loads at 5-10 km/h, is my guess. Mind you, it was replaced due to the weak superstructure.
