The Great North Road runs through the town (now B1164), though the majority of traffic now uses the modern A1 trunk road, which splits the town in two. The town was bypassed in July 1967, opened by Stephen Swingler. The section of road, known as Carlton to Markham Moor, or the Sutton-on-Trent, Weston and Tuxford Bypass, was built by Robert McGregor & Sons, with concreting aggregates supplied by Hoveringham Gravels (later bought by Tarmac). The eight-mile section was authorised by Tom Fraser with a contract for £2.7 million, but ended up costing £3.4 million. The section is notable for the first use in British construction of the slip form paver using pervious concrete. The bridge sections came from Boulton & Paul Ltd in Norwich.
