Cold Hesledon Interchange, occasionally known as Murton Interchange is a juntion on the A19 in County Durham. Originally a junction on the B1285, it was reconstructed slightly to the south to serve the newest section of A182 into Seaham. Three new slip roads were built, with only the northbound on-slip remaining of the original junction. Three roundabouts are therefore needed to serve all routes, with a new link road - apparently a spur of the B1285 - built alongside the A19 to connect them. In 2016, the roundabout on the B1285 was replaced with a traffic-light controlled crossroads.
There is a stopped-up exit at the junction, once intended for a road known as the East Durham Link Road which was to bypass Murton and meet the B1285 near Eppleton Hall, with a spur reaching the A182 near Easington Lane. About a mile of this route was completed in 2008, ending at a roundabout built to provide access to a business park. Although planning permission for the business park was granted in 2007, nothing was built for the subsequent ten years leaving the new road unused and inaccessible to traffic. As of 2017, it is unclear whether the full route will ever be completed. It is not clear, had it been built as planned, whether it would have been numbered A182 or B1285.
