 The three-route proposal was perhaps prematurely announced, aligned with particular developer landowners' interests in mind, over the interests of others.One of the constraints to implementing Smartlink is the lack of height and width underneath the existing "Newtown Road" bridge, which lies upon the Cheeseman's Green route.The existing bridge headroom only allows use by mini-buses, restricts two-way traffic and only incorporates a narrow elevated footway on one side of the carriageway.
