It says built in 13 hours but usable for traffic in 4 weeks, and I am trying to parse that.
There was a temporary pontoon bridge then, and then a more permanent bridge for traffic built? I ask because pictures I initially saw were quite larger than the initial bridge, which made me question the within a day time.
I suppose it depends if the Gaza pier is closer to the first than the second. While the Gaza pier is described as temporary, it seems built to handle high and continuous cargo traffic. I imagine constructing such a platform which is also seaworthy enough to be towed requires more tasks than a single lane pontoon bridge. I also wonder how much of the Gaza pier had to be adapted and customized compared to pre-fabricated bridge segments.
Given the difference in type of work, and prefabricated material I wonder if 4 weeks is reasonable or not still. An example of similar maritime construction would be useful I suppose.
