Fount of all knowledge request:

Our local council has given notice of closing a local road for a week or
so.

Typically, instead of asking the local paper to notify readers that "the
road from A to B will be closed for X from DD ...", they have taken an
advert in the form of a Public Notice, and stated the po-faced bare
facts: "the C123 will be closed from its junction with the U456 to its
junction with the U987".

Since only the highway people themselves know what the C123, U456 and
U987 actually are, we are somewhat in the dark.

I'd like to look at a map which identifies these roads. Googlemaps
doesn't seem to do this. Does any online map?

Thanks a lot for any advice,
John

p.s. I recognize the 'legal requirements' placed upon local councils,
but what harm would it do for them to also get the paper to publish a
brief, informal, and highly informative article, which we could all
understand?
