M3 Bagshot Heath Footbridge - 9 April 2025
Update from National Highways outlining the next steps for the long-awaited footbridge installation
The Bagshot–Lightwater footbridge spans the M3, providing a key walking route between two connected communities. Since its closure on 3 October 2023 due to safety concerns, residents have faced a 3.3km diversion with multiple hazardous crossings — disproportionately affecting those without access to cars or public transport.
Dear Dr Al Pinkerton,
Re: M3 Bagshot Heath Footbridge - 9 April 2025
I’m writing to inform you of our upcoming weekend closure to the M3 between junctions 3 and 4 in both directions for the installation of the new footbridge at Bagshot Heath.
Our planned dates to undertake the bridge installation are from Friday 25 April to Monday 28 April. To ensure we can complete the installation safely and efficiently we’ll be staggering the start of the closures required over the weekend.
Friday 25 April
We'll close slip roads and carriageways in phases:
• 12 noon - M3 junction 3 southbound entry slip road closes (this will allow us to have the bridge in situ ready to be lifted over the weekend)
• 7pm - M3 J3 to 4 northbound (London-bound) carriageway closes
• 9pm - M3 J3 to 4 southbound carriageway closes
Monday 28 April
• 6am M3 reopened between junctions 3 – 4 in both directions.
Once the bridge is in place, we will need 10 overnight closures of the M3 (five on each carriageway) to safely fit mesh and anti-climb measures before the footbridge can be opened to the public.
As these works are weather dependent, we have also booked the weekend of 9 May to 12 May as contingency.
We will be letter-dropping the local community to advise of the upcoming weekend closure, using electronic and hard standing signage across the network and also utilising our social media channels to communicate the weekend closure.
If there are any changes to our planned weekend closure we will be in contact to advise of them, in the meantime the most up to date information on the works can be found https://nationalhighways.co.uk/our-roads/south-east/m3-bagshot-heath-footbridge/
Yours sincerely,
National Highways
