Let's start a thread about Bulgarian motorways and other highways.
Time is not proportional with length...both the 30 km of M43 here and 200km of M6 will be inaugurated in 2010...and both were started this year.But if so what is it taht takes that long to build the motorways? 20 km 2 year, that´s unbelievable.
M6 has 4 tunnels,1km is the longest...with a lot of smaller-bigger bridges. Time is not an element in the equation. It only depends on how many people work on it. Remember,even bridges were built under 1 night in WWII...I assume it depends a lot on the number and length of bridges, viaducts and tunnels... the M43 for instance has to cross a major river (Tisza).
