I think many 1860s / 1870s railroad bridges would still be standing today if it wasn't for the world wars. The U.S. still has many railroad bridges from that era in use.

The reason compared to the more recent bridges might be overengineering because of lack of skills related to statics and strength of materials. Most notable modern bridges would not be designed without the computerized Finite Element Method invented by the aircraft industry in 1950's.

I think that's likely the case. Many monumental 1930s bridges are still going strong around the world while many 1950s and 1960s bridges are structurally deficient. They were built too lean to cope with the growth of traffic and the weight of trucks.

That seems to make the Storstrøm Bridge an outlier though. Perhaps it was affected by the salt water more than other bridges.

One reason is that modeling dynamic forces (especially aerodynamics and vibration) needs a lot of computing power. Quite many of those problematic bridges over Rhine in Germany are cable-stayed bridges. There are more rigid than suspension bridges, but it seems to be me that they still are not free from steel fatigue caused by excessive vibration. The impact of vibration increases as the span width grows. The fatigue is very difficult to be modeled.

The Hännilänsalmi bridge on 4/E75 in Finland had to be removed after 50 years of lifetime only because of its very bad condition. Most of the main steel structures suffered from fatigue, and traffic restrictions had to be introduced before the replaced bridge was complete.

Was Lillebælt built more robust?
The main difference between the old dual bridges crossing the Storstrømmen and Lillebælt, is that maintenance on the Storstrøms-bridge has been neglected for many years, and that is not the case for the bridge crossing the Lillebælt. The Storstrømsbridge has since the motorway bridge opened in 1985 only carried a relatively unimportant local road (AADT under 5.000) and a regional railway carrying less than 100 trains a day (incl. a few international trains) vs. the bridge crossing Lillebælt which carries a local road with an AADT of approx. 10.000 + the main Danish railway, connecting all larger Danish cities, carrying more than 250 trains a day, plus up to 96 international freight trains a day between Scandinavia and the Continent.

More 130 km/h motorways

The Ministry of Transport has announced that a further 70 km of motorways will have their standard upgraded to conform with the the general speed limit of 130 km/h and thus have the speed limit raised from 110 km/h to 130 km/h. https://www.trm.dk/~/media/files/pub...raekninger.pdf

In addition 150 km of ordinary 1+1 roads with a 80 km/h speed limit, will be upgraded to have their speed limit raised to 90 km/h. https://www.trm.dk/~/media/files/pub...-landeveje.pdf

It has further been announced that it is being investigated whether some of the remaining motorways not conforming to 130 km/h, can have their speed limit raised to 120 km/h from the current 110 km/h.

New government motorway initiatives

The governments 2018 budget proposal will be presented soon. But as appetizers for the budgetproposal the government has allready presented a few good-bites.

That includes:
Allocation for shoulder running on the E20 West-Funen as intermediate measure until funds are available for the full widening to 3+3 https://www.trm.dk/da/nyheder/2017/e...-i-myldretiden

Launch of EIA process for widening of two sections of E45 in Eastern Jutland from Vejle N - Skanderborg S and from Aarhus South to Aarhus North from 2+2 to 3+3. Widening of the section in between from Skanderborg S to Aarhus is allready in construction with completion in 2018-19. https://www.trm.dk/da/nyheder/2017/r...6-spor-paa-e45

In addition to Skanderborg S and Aarhus S that will be a nice 67 kilometer expansion project!

The government announced that the toll rates for the Great Belt Bridge will be reduced by 25% in steps between 2018 and 2021. This will extend the repayment period of debt of the Great Belt Bridge by 3 years to 2031.

No, let's not, the Stora Bältbron makes sense cause it's domestic, it helps binding DK togehter, it should be free like Ölandsbron or Högakustenbron.
However there is a point in keeping Öresund expensive, nothing positive can come from making the border even more porous.
Honestly the bridge has been a disappointment , just think what we could've built with that money, the boats where better and mostly allowed just meaningful travel, maybe one day we can demolish the bridge.

The problem of the bridge being too porous a border is easy to solve: Just rollback the Treaty of Roskilde in 1658.

Then you harmonize Danish and Swedish legislation and migration-penal-processes. Problem solved in due time. Why come to Sweden if it's under same conditions as in Denmark, and vice versa.


(Another thing most Swedes who want to put up a machine gun on the bridge never consider: Compared to pre-1990 there are free borders across the Baltic Sea as well. It is within 90-150 kms of distance to Germany/Poland/Baltic states to the Swedish coastline. Would you like boat migrants instead?)

The problem is not in the infrastructure itself, which is doing its job perfectly but the inadequate and lunatic migrant policies of Sweden in the last 20+ years. No matter if there is bridge, tunnel or Hyperloop, until giving money and accepting every poor soul from the Middle East and Africa is the way to go, the 'doctors and engineers' will keep coming..

Well sorry for going on topic, but I can tell that the many years of expansion work at Køge Bugt Motorvejen is finally done.

As of tonight all 4 lanes in the northern direction has been painted (or what its called) and the emergency lane is done as well.

I will try to get out tomorrow and snap some pictures.

As promised, the first pictures are from the Egedesvej Bridge and the second set of pictures are from the Ølsemaglevej Bridge.
