highway bridges and roadways

The 35 w bridge that went down sure has woke up american people that is if CNN and MSNBC keep up the programs on highways deficient problem. I read where the Highways in Germany last much longer than does the highways in the US. From what I have seen - there is not deep enough base put on but anyway supposedly the Contractors guarantee the roads for several years. I saw where Bill Neye the science guy was explaining why bridges may fall down. The corrosion is apparently a factor as the maintenance covers them up with paint after clearning the surface so the metal over time gets thinner. The bridge gives as the traffic goes over the bridge so if the metal is tied to the ends eventually gets weaker then there is not enough metal to support the concrete driveway. That is apparently what happened on the 35W bridge in Minnesota and from what have come out - the troubles were known . Hour highway system is an interstaate system so the State Government is not completely in controll and matter of fact most of the highways are built with 90 percent federal and 10 percent so in effect the federal government is really the responsible party . I remember when Eisenhower built the plans came out of the defense dept because the states either could not afford the highways or because of local problems would not build the the highways system. When the states got involved in the planning what did they do but make many of the highways in local streets and effectively destroy the national system of the defense highways that were designed for defense and national transportation system. Just to change the thoughts with the Railroads under a big profit system- the road Beds are not made to honestly haul extreme heavy loads and at speeds that would make for a better transportation system. For instance in Europe - trans go 200 or even 300 miles per hour and also in Japan. What is wrong with this country? Is profit system so based on profit that we do not actually have a decent railroad system. Once of the causes of the great depression is the Railraods broke down and railroad barons took too much profit. Now we are in the process of the selling state highway systems to private enterprises and what will happen to our Highway sysstem when they want to take more profit out of the transportation system. There is only a true profit system of the most of 20 percent and when these corporations want to take more than that then the country really suffers as the average worker can not pay that much with pure wages. this is a subject I will write more late on.
