We're keeping two-way traffic lights on Fryerning Lane bridge while we work with the local authority on a long-term solution.

Works

We repaired bridge damage caused by a road traffic incident in 2018. Our detailed assessment shows the bridge is safe to use, but the edge beams need protection from vehicle loading.

Closures

There are no road closures. Protective barriers near both verges have narrowed the road, so the bridge cannot safely carry two-way traffic at the same time.

Diversions

There is no diversion route. Two-way traffic lights are in place to control traffic over the bridge.

Next steps

We're working with the local authority to identify a long-term solution and will share more information once the next steps are confirmed.

Diversion routes: No diversion route. Two-way traffic lights remain in place on the bridge to manage traffic safely.

We’ve temporarily closed the west footway on Bascule Bridge after identifying damage to the surface.

We found a defect in the concrete at the start of the footpath which has created a trip hazard for people using the footway. 

Our contractors are investigating the issue and finalising how we’ll repair it.

We’ll start work as soon as possible and re-open the footway once it’s safe to use. 

Bascule Bridge remains open and fully operational. This closure only affects the west footway. 

Closures

A12 Lowestoft Bascule Bridge west footway

Closed 24/7 until further notice.

Diversions

If you need to cross the bridge:

• use controlled crossing points 
• safely access the east side footway 
• continue your journey across the bridge 

Please remember that closures can change at short notice. You can check the latest information on our daily closures page. Our travel alerts give details of live incidents on our network.
