Thoughts about next Tuesday. Having experienced total traffic chaos on the PP roundabout for the Norwich Carabao Cup game and noticing from ongoing traffic reports that the situation seems to getting worse rather than better, I would suggest some warning notice needs to issued by the Club. With away fans travelling and arriving in numbers along the M25/M23 route, I can foresee an evening of travel chaos unless supporters stagger their journeys, not so easy for an evening kick off. A warning notice on both the CTFC and Colchester Official web sites would seem the absolute minimum to alert fans of the potential problems but also contact with the Highways authority and Police would also seem a sensible course of action to see if anything could be done to relieve congestion ahead of kick off time. I assume parking availability will continue to be provided at the Tilgate Forest Business Centre and again publicity and confirmation from the Club would seem a good idea.
I believe the travel chaos you refer to as a large vehicle broken down (I may be wrong) but I can assure you having travelled that route post Norwich it's no longer blocking the road. However, yes any bigger attendance always a good idea to allow a little extra time.
