I don't think that Kidderminster's deterioration can be entirely blamed on the subways, except perhaps for right at the beginning when the 'concrete collar' was first constructed (or not completed - I believe it was a process which took approximately 15 years from the late 1960s onwards). Kidderminster is a 'has-been' town - once its identity as a carpet manufacturing centre had been destroyed it became a faceless dormitory area which couldn't compete with the superior retail experience at Merry Hill, Redditch, Worcester etc. The Weavers Wharf development of the early 2000s was intended to be an expansion of the existing retail facilities but the plan was banjaxed by the economic downturn later in the decade, leaving the once-bustling Worcester Sreet as a ghost street. As you know, it has now been de-pedestrianised and the former Woolworths and Littlewoods stores have been demolished.
Would Safari Park and SVR visitors
ever go to the town centre on foot? The former is some distance out of town and the latter, even with no ring road, is still at least half a mile away.
You wouldn't find much if you did - the town centre is down the hill
