True, it is one of the main routes into town, but football matches don't take place when those roads are at their busiest. In any case, people should think about not driving there, if they can avoid doing so. By the time we have moved, we will have a far better idea of how public transport will cope.
The new trains hold twice the number of passengers as the old ones and hopefully we will see an increased time table for match days.
Next week LCR will also certainly vote for the bus service to be re-regulated and Steve Rotheram will be able to dictate that there is sufficient bus provision on a match day for the new stadium by the time we are there.
In short, it WILL be alright on the night (and day). IMHO, of course.
