World's longest bridge?

Posted by wangi on 1 December 2016 in English (English)

The 63km of Lonowai's bridges / trestles (/ causeways?)! The existing set was recently upgraded with a new 25km bridge to Lito.

It's not feasible, is it? Sea would be far too deep.

Location: 10 Kilometer Bridge, County of Motu'u, Lonowai District (Gobrassanya)

It's theoretically possible in engineering terms, as the sea would be shallow around the islands. But it's highly unlikely that the economics would be worth it for the level of traffic. Perhaps if there were two big cities at each end, but not for a few small islands. The entire island chain would have only a few thousand motor vehicles and the cost of fuel would be inflated by the necessity of importing everything. Any goods that were needed would come from the mainland on a ship, and small boats would satisfy the other transport needs. A fifty-mile bridge over the sea would have a cost many times the GDP of the islands.

Also, if Mount Lito is an active volcano then the islands would be at risk of earthquakes with all the tectonic activity. Then there's the coral reefs, which are doubtless protected by all sorts of international environmental laws.

Just another example of the "infrastructure fetishism" that manifests in OGF. But, as we have been discussing elsewhere, verisimilitude, its definition and enforcement, has been and will be an ongoing issue in OGF. We could make a "just so" story, about a Lonowai billionaire with a bridge obsession insisting on connecting the islands, and no one could argue against it, right? It is, technically, possible, if rather implausible.

The longest bridge I've seen in OGF was one connecting West Island City and Ocean City in West Commonia, around 180km of bridge, plus connecting islands. I tried to contact its builder (to find out who the billionaire behind it was etc) but no result. I downgraded most of it to ferries, but this still could do with some work. It is very easy to draw long bridges quickly. This new bridge section has some additional implausibility, since you can only turn one way onto it and off it.

Off course, the whole of the barrier island system is implausible: if those islands are volcanoes - which is what they look like - there would be fringing reefs, plus atolls, rather than a barrier reef system. The direction of movement of the tectonic plate over the hotspot would affect the distribution of the volcanoes and hence the formation and distribution of the reefs, as here.

The massive Bridge in West Communia is gone

The massive exstension is possible. Just look at the Keys Highway. it floats above the ocean.

The Overseas Highway of the Florida Keys was in my mind. However, it's massively different. It's going over the string of keys, with individual spans up to ~ 7 miles max. The Lito bridge is 25km. The Overseas Highway is a two lane road. The Lito bridge is grade separated.
