M27 Southampton: Route Overview
The M27 Southampton is a key spine of southern England’s road network. Running roughly east to west along the coast of Hampshire, it connects the M3 near Eastleigh to the A27 corridor near Portsmouth, with Eastleigh and Hedge End serving as notable points along the way. While the motorway does not pass directly through Southampton city centre, its northern outskirts and surrounding towns rely on the M27 Southampton for quick access to the national road network and the Port of Southampton.
From its western end, the M27 Southampton begins where the M3 transitions into a broader coastal route. It continues eastward past expanding suburban towns, industrial estates, and shopping hubs, before reaching the Fareham area and ultimately linking with the A27. The motorway is a workhorse for both domestic travel and freight movements, connecting to the important port traffic that Southampton handles daily. For travellers and logisticians alike, the M27 Southampton offers reliable connectivity between inland centres and coastal destinations.
