A40 Gloucester bridge works prompt warning to parents

Parents in and around Gloucester are being urged to plan extra time for the school run as major refurbishment of the A40 Over Bridge continues into the new academic year, with lane closures and a long-term slip road shutdown expected to prolong rush-hour delays.

Refurbishment timetable overlaps with return to classrooms

Published updates show that essential maintenance on the A40 Over Bridge at Over, just west of Gloucester, will continue from June 2026 through to March 2027. The programme, managed on behalf of National Highways, involves structural repairs, new waterproofing and drainage improvements on the busy Severn crossing.

Recent progress information indicates that a key traffic milestone was reached at the end of July, when vehicles were moved into a single-lane contraflow on the westbound carriageway so that work could begin on the eastbound deck. This arrangement is set to remain in place as the new school term begins, concentrating all traffic on one side of the structure and reducing available capacity at peak times.

With the bridge carrying an estimated 5,000 vehicles an hour during the busiest periods, local reporting has highlighted the potential for sustained congestion as families resume daily trips to schools in Gloucester and surrounding communities in early September.

Lane restrictions and slip road closure shaping congestion hotspots

The A40 Over Bridge scheme has already brought a series of changes to familiar routes. Publicly available project details confirm that lane 2 in both directions was closed earlier in the summer to allow central reservation works ahead of the contraflow, with drivers now funneled into a single lane in each direction across the structure.

In addition, the dedicated slip road linking the A417 Over Causeway to the A40 westbound has been shut and is expected to remain closed for the duration of the project. Local coverage notes that this restriction is forcing some motorists onto alternative junctions and local roads, increasing pressure at key approaches to Gloucester from the Forest of Dean and Ross-on-Wye corridors.

While monitoring suggests that traffic has gradually adjusted to the new layout, early phases of the works saw queues building at peak times. As weekday traffic volumes rise again with the start of term, transport observers anticipate that morning drop-off and afternoon pick-up periods are likely to be among the most affected.

Parents urged to plan ahead for September journeys

As families prepare for the return to school, Gloucestershire County Council’s latest member briefing on the scheme encourages road users to plan journeys in advance and consider alternative routes where possible. The note acknowledges that the combination of term-time traffic and continuing lane closures may lengthen travel times on the A40 corridor.

Health and education bodies serving the area have issued similar reminders in recent months in relation to appointments and college transport, advising service users to allow additional time when traveling through known roadwork zones. The same message is now being applied informally to the school run, particularly for those who must cross the bridge to reach schools in Gloucester from the west.

Parents of pupils using school transport are also being advised, through wider regional guidance, to keep in close contact with operators during periods of disruption and to check any updated pickup times or diversion routes that may be introduced while the bridge works continue.

Impact across the wider Forest of Dean and Severn corridor

The A40 Over Bridge is a critical link between Gloucester and communities in the Forest of Dean, Ross-on-Wye and beyond. Regional news coverage earlier in the year warned that drivers should expect prolonged disruption for much of the construction period, with forecasts of heavier queuing on approaches to Over roundabout and Highnam roundabout during the morning and evening peaks.

Reports describe a combination of contraflow running, narrowed lanes and intermittent overnight closures for specific tasks such as installing traffic management and switching work zones. Overnight work has been used to complete some of the most disruptive operations, but daytime lane reductions remain the main constraint on traffic flow.

Online commentary from regular commuters suggests that while some have adapted by leaving earlier, others have diverted onto alternative routes through local villages, raising concerns about rat-running and knock-on congestion away from the main A40. Transport planners are continuing to encourage drivers to follow signposted diversion routes rather than using minor roads not designed for high volumes of through traffic.

Advice for families navigating the autumn term

For households preparing for the first school run of the new term, transport and local government information points to a number of practical steps. Parents are being encouraged to check the latest updates on the A40 Over Bridge works before term starts, build extra time into their usual commute, and consider sharing lifts or using public transport where it is available and convenient.

For shorter trips within Gloucester itself, active travel options such as walking and cycling are being promoted in other local transport campaigns as ways to reduce pressure on main roads during peak hours. While these alternatives will not be practical for every family, they may help some pupils avoid delays associated with the bridge works.

Project updates stress that despite occasionally quieter visible activity on top of the bridge, work is continuing beneath the deck and on concrete repairs that require strict curing times and low vibration levels. The emphasis from published information is that the scheme is designed to extend the life of the structure and reduce the risk of emergency closures in future, but that short-term disruption, particularly around the school run, remains likely for the coming months.
