This is a very similar puzzle to last week’s, with a couple of minor tweaks.
Crosstown is on a straight line between Lefton and Righton.
Crosstown is also on a (different) straight line between Upton and Downton.
Unlike before, these two lines do NOT need to cross at right angles.
As before each of the distances between towns should be a unique whole number of miles.
However now there is the added restriction that none of the distances should be a multiple of 3 (although U-D and/or L-R could be as they are each the sum of two separate distances).
To complete the puzzle you just have to find a set of distances which satisfy all of the restrictions. For extra kudos, can you get the total length of the eight roads to be less than 400 miles?
