If you Google: Gravely Hill interchange , the is a great article there.
I did that same walk to go to and return from, home games at Villa Park during the period it was being built. I used to walk/skip along that raised concrete between the pavement and Salford Park (shown at the left of the first picture). It was about six inches wide, so it was no tightrope, but I wished I had that sort of balance now
. There also used to be a pedestrian walkway between Slade Road and Lichfield Road Pictures 2 & 3), which was closed some years ago, because it wasn't ever the safest of routes to take, particularly after it got dark.

The build started in early 1968 and was completed in 1972 , the build time does not include design or preliminary site investigations.
I would have thought that they had to às ìt was a DOT Gov contract

When I worked at Digbeth Coach Station in the late 70s, we were visited by some government chappie (Ministry of confusion & public nuisance?) to tell us that traffic would be restricted on Spaghetti Junction whilst repair work was carried out, and that this would be necessary every few years for the rest of its life. He actually said that parts of it were so badly designed and built that in the long run it would be cheaper to tear down the whole elevated section of the M6 and rebuild it, but they couldn't because there was nowhere to divert all the traffic to.like everything concrete eventually wears out

Spaghetti Junction in Birmingham is actually called the Gravelly Hill Interchange and began construction in 1968, learn more interesting facts here!
There has been many developments in concrete technology since the 70’s via chemical additives to give plasticity and ductility to the concrete , also high performance concrete, self setting concrete to reduce shrinkage and voids.
I quite agree, and from what the chap said concrete technology (and inspection during construction) had already improved within the time since the junction's building till then, and it is bound to have improved a lot more since. The current construction of HS2 is bound to increase it more, as well.
