Do you not think it'll be an improvement on the traffic lights currently in place? I would have thought the majority of the traffic will be flowing east to west and vice versa so would assume the traffic flow will be improved.
I do live on said potential rat run. AFAIK said rat run will be closed off after construction although still usable for a bus route so I have no idea how that will be monitored
I'm not totally for the development and neither am I against it, however those that continue to oppose the development due to traffic should put their time and effort into getting a proper bypass of Worthing and Lancing green lit.
