 Additionally, it was proposed that the existing A5 could be upgraded to full dual carriageway grade separated standards together with improvements to the A41 and A464 trunk routes.The first section of the M54 was opened in 1975, then named the A5 Wellington bypass (bypassing one of the existing towns which formed part of Telford), but renumbered the M54 in 1983 when the motorway was extended.The bypass removed traffic from the heavily congested route through the urbanised areas of Oakengates and Wellington, and removed one of the country's most notorious bottlenecks at the Bucks Head crossroads, in Wellington; delays of up to six hours could be experienced in the summer months.
