The A31 joins the M27 at Cadnam and from there the M3 to London and the A34 to the Midlands and the North can be accessed.[93] The main road west is the A35 to Honiton in Devon which runs through the South East Dorset Conurbation and continues east as far as Southampton, albeit as a non-primary route.[94][95] The A350 in the neighbouring borough of Poole provides the only northern route out of the conurbation.[96] National Express coaches serve Bournemouth Travel Interchange & Bournemouth University.
