This would save the highways a small fortune.
Our motorways cost far too much, if we take the time to look at other counties in the EU their autobahns and motorways. Their lanes are not as wide as our, far less of their roads have lighting nor do they use as many cats eyes.
Reduce the lane widths, cut lighting and reduce the number of cats eyes used.
We could even get the Royal Engineers to repair roads this would save us a fast fortune.
