Welshpool / Y Trallwng is a town in mid Wales, not far from the English border.

1969 bypass proposals

By the 1960s traffic congestion in the town was becoming a problem. A bypass, or rather a throughpass, was planned to relieve the town centre. Traffic studies revealed less than half the traffic was passing through so therefore a route within the town would capture more traffic than an outer bypass. The route chosen made use of a derelict canal which by then had become unnavigable. In addition the A458 would also be relieved by upgrading Brook Street. The two routes would meet at a large roundabout. Several alternatives were considered for this junction including some with grade separation but the roundabout as planned was expected to provide enough capacity for 30 years.

Objections came in as soon as the route was announced. The main concern was the loss of the canal. At the time there seemed next to no chance of ever restoring it as it was already severed in places and the cost of restoration was prohibitive. The local council's objection triggered a public inquiry which in 1971 recommended the scheme not proceed in its present form.

The town had to wait twenty years for its bypass which eventually opened in 1993 running parallel to the railway which was one of the routes rejected in the original proposals. The canal has since been restored in places and work progresses to eventually open the full length to narrowboats. The decision to abandon the 1960s bypass was the right one.
