Is this sensible?

[Simpo Two]

For the last 5 days the centre of town has been largely stationary thanks to some 4-way roadworks.

A new bridge? A motorway? What feat of civil engineering warrants this much work? I investigated...

Walking down towards the high street we see this... lots of signs:



What is going on, we wonder... They've been fitting stuff under the pavement. That explains why the footpath is closed.



But one lane of the road is closed too, with a barrier all round it - what's going on in the road? Well in fact, nothing at all:



There are some more roadworks going on on the other side of the road, and another chunk of road surrounded by barriers. Something's going on there. Or maybe not:



So apart from one pavement closed, there doesn't seem to be any need for any of these two fenced off pieces of road and no need to stop traffic. Let's venture on down to the high street... the amusement continues:

Looking to the right we have traffic light, cones, a barrier and a closed bus stop:



Here's a nice queue of traffic, waiting for, well, nothing at all:



Walking up to the other end of this set of lights we see:



And in the middle, the zebra crossing is closed:



Looking back up the road we started from, we now know there's nothing apart from a small trench in the pavement on the right hand side...



Is that really all warranted, and how many hours of people's time have been wasted as they sit needlessly at traffic lights?
