Yes - you should be able to go to the local library and photocopy 1:1250 OS maps for the cost of the copying. You'll have to do it in bits, but you'll be able to stick together a map that will be just under a metre long. Most London Boroughs have put their 1:1250 maps in one library in the Borough - I see that you're in Lancashire, so it would be best to check with the Library Department before pedalling down there
Failing that you can buy 1:1250 maps which are stored digitally from a host of re-sellers, usually map stores in major cities. The OS website gives details. This is expensive
Failing that you can buy online in different formats - .dwg or .pdf if memory serves. This is expensive.
Failing that you can go to Streetmap and print off little bits of your street and then stitch them together. Give yourself a bit of time for what will be a boring task.
(later edit) there is one wizard wheeze you can try. Some areas are covered by historical maps which the OS sells for not much. If your street is the same as it was in the 1890s, or close to, you can pick up the historical map for next to nowt
(second later edit) I would get your map, buy a roll of tracing paper, and use a series of sheets of tracing paper thus - draw out the major lines - property boundaries, kerbs, junctions and so on in bright felt tip and then mark up with stars, arrows whatever to make your point about conflict points. That's going to be a whole lot easier to read at a meeting, and, if you have a series of these traced diagrams it gives other people the chance to make a point with the minimum degree of fuss and misunderstanding
(third later edit) I'd get another map showing the locality - a blow up of google maps would do
http://maps.google.co.uk/ and use that to show what you think is the genesis of the problem - whether it be rat-running between major streets, or people seeking a way past a jam on a major street. The point is that you can show that the use made by motorists is not what the street was designed for - useful when talking to your local councillor.
(fourth later edit) the great virtue of 1:1250 maps is that they are fantastically accurate. I've used them to plan buildings on prior to getting a measured survey and the difference between the two has been tiny - on one occasion 18mm over a 100 metre site. That's important to your case, because you will be able to measure the width of the road and compare it to the design widths in the highways section of your Council's UDP/LDF, which might say that a secondary or residential road should be (for instance) 7.2 metres wide. If it turns out that your road is less than 7.2 metres wide you will press a button with the Council
(fifth later edit) don't forget that the accuracy of the map will enable you to plot blind spots. Highways officers really do dislike blind spots.
