Not to worry, it's only a training exercise. Hence the 'employees' being training dummies incapable of actual work as opposed to proper minifigures (ignore the lack of minifigs to direct the dummies).

There's just something magical about those red wheels and black tires

One of my first sets. Loved it to bits!

Having just renewed my construction safety certification, all I can see are the health violations…

And this is why road work always takes an eternity. Most realistic Lego set ever!

What kind of front loader has three axles?

I guess they intend to have it look like a tracked vehicle.

I have the trailer from this set. One whole specialized part, including wheels. But I like it, it's functional and my 4 yo can easily play with it with his current lego bricks. 50 year old part but works with the system as a charm!

What health code violations? Both of these guys are clearly dead. They're stiff as a board!

At least it looks like the 'figures' can actually get in to operate it. Kind of rare for this era.

Which, in and of itself, is several violations and probably some kind of felony

I’d buy this today.

Not me, they're very fragile, I broke so many in my days

This is very moody background art. I love it!

They definitely look like the workmen that my local council employ… standing around with their hands in their pockets

Me too. I think I've got more broken than intact ones from back then, but I bought replacements via Bricklink, since I just like the look of them so much more than of all the others that came later. And of course nowadays I know how to be more careful than as a kid.
