A popular route over the M4 motorway in north Bradley Stoke is to be closed for six weeks from Monday (27th July 2020) to allow Highways England to carry out bridge refurbishment work.

Trench Lane, which runs between the roundabout at the eastern end of Woodlands Lane and Old Gloucester Road (near The Grange Hotel), will be closed 24/7 to all motorists, cyclists and pedestrians.

The Journal understands that it is only the section of road in the immediate vicinity of the motorway bridge that will be closed, so all businesses located off Trench Lane will continue to be accessible, albeit only from its eastern end, i.e. via Old Gloucestershire Road.

A signed diversion will be in operation via Woodlands Lane, Bradley Stoke Way, Winterbourne Road, Old Gloucester Road and Trench Lane; and vice versa.

The planned work is a ‘full bridge deck refurbishment’, which will include concrete repairs, re-waterproofing, resurfacing and joint replacement.

In a letter sent to stakeholders and local residents, Highways England writes:

“We would not normally do works under a full closure in the summer, but following consultation with South Gloucestershire Council we have been restricted to undertaking these works over the school summer holidays to prevent disruption to Bowsland Green Primary School.”

“Please accept our apologies in advance for any inconvenience this may cause. We always aim to work to the programme however unforseen circumstances, or adverse weather may mean changes to it. We will make every effort to ensure the impact on the local community and travelling public is kept to a minimum.”

The end date of the work period is given as 1st September in the letter to stakeholders, although signage on site shows this as 3rd September.

Anyone with questions or comments about the work is invited to contact the Highways England Customer Contact Centre (open 24/7) on 0300 123 5000 or by email at

Updates will be published on the Twitter feed of Highways England (@HighwaysSWEST)
