The Segensworth Roundabout and A27 Traffic
Daily congestion on the main road corridor
The Segensworth roundabout and the A27 corridor through western Fareham are the main sources of traffic congestion for Locks Heath residents, and the daily experience of navigating these roads shapes attitudes towards transport and infrastructure in the area. The A27 connects Fareham to the M27 and the western suburbs, carrying a mix of local, commuter and through traffic that exceeds the road's comfortable capacity during peak hours.
The Segensworth roundabout sits at the junction of the A27 and the roads serving the Segensworth commercial area. During the morning and evening rush hours, queues form on all approaches as commuters, shoppers and commercial vehicles compete for space. The roundabout's capacity has been improved through traffic light control and lane marking, but the fundamental constraint of too much traffic for the available road space remains.
The morning peak typically runs from seven thirty to nine o'clock, with the heaviest flows on the A27 westbound towards the M27 and eastbound towards Fareham. Locks Heath residents joining the A27 from Warsash Road or Hunts Pond Road encounter queues that can add ten to twenty minutes to their journey on bad days. The evening peak is similarly congested, running from around four thirty to six thirty.
The A27 itself is a single carriageway road that was not designed for the volume of traffic it now carries. The road passes through a continuous built-up area with numerous junctions, pedestrian crossings and speed restrictions, all of which reduce its capacity and create the stop-start flow that characterises the peak-hour experience. Proposals to improve the A27 have been discussed for years, but the cost and complexity of widening or redesigning a road through an established residential area have prevented significant progress.
For Locks Heath residents, the congestion on the A27 and at the Segensworth roundabout is a daily reality that influences journey planning, departure times and route choices. Those who can adjust their working hours to avoid the peak are at a significant advantage, and the growth of flexible and home working has reduced the morning peak for some, though the school run continues to generate traffic regardless of working patterns.
Alternative routes exist but are limited. Cutting through residential streets to avoid the main road congestion is a tactic that frustrates residents on those streets and does not significantly reduce overall journey times. The fundamental geography of western Fareham, with limited east-west routes, means that the A27 carries a disproportionate share of the traffic and there is no easy bypass.
The impact of the congestion extends beyond journey times. Air quality along the A27 corridor is affected by the volume of traffic, particularly during the slow-moving queues when engines idle at low efficiency. Noise from the traffic affects properties close to the road, and the stress of sitting in daily congestion has a measurable effect on wellbeing. These impacts are borne disproportionately by the residents who live alongside the road.
Future traffic levels will be influenced by housing development in the area, changes in working patterns, the uptake of electric vehicles and public transport improvements. None of these factors is likely to eliminate the congestion in the short term, and Locks Heath residents should expect the A27 and the Segensworth roundabout to remain challenging during peak hours for the foreseeable future.
