I am less impressed with the chosen location past this point which adds an extra 4.5 km travel distance. An earlier concept had the bypass heading directly to TC 1 at the curve east of SK 6. A more complex and expensive connection at the west end for sure, but saving of 11 km of new freeway.
This design really left me scratching my head. Looking at this area, it seems ROW and frontage roads really should not have been a problem. A 3-way interchange at the west end (a trumpet, even?), I'd think would be simpler than this ponderous 4-way mess they have there now.
Sure, there'd need to be a new split with SK1/6, but OTOH, no need for the SK6 interchange south of town. And as you said, save 11 km of new freeway.
How does this get the green light? Direct & sensible routes aside, don't people wanna build things cheap?
