Diversion route via Wisbech revealed for A17 Cross Keys Swing Bridge work in Sutton Bridge

Highways bosses have revealed the official diversion route details that will be in place during works on Cross Keys Swing Bridge, which has begun this week.

Paint and maintenance was due to start yesterday on the structure - which forms part of the A17 at Sutton Bridge.

Traffic management systems are in place - with the key crossing not closed - but highways chiefs have published a long alternative route for those who want to try to avoid congestion.

Signs are in place across the area directing traffic along a 'triangle' of the A17, A47 and A1101 - taking people via Wisbech to reach King's Lynn and adding more than 10 extra miles to the journey.

Maintenance work for the bridge will take place from Monday February 28 and continue until July 1.

Highways bosses have promised to try to minimise the disruption for road users during that period.

Some elements of the programme of works will mean that the bridge has to be closed – when the ends of the bridge are painted, for example – and during this time the diversionary route will be the only way to cross the river in the area.

During public holidays, the restrictions will be removed completely.

Coun Richard Davies, executive member for highways said: “We are working very hard to get the vital works done as quickly as possible in a way that causes the least amount of delay for road users at the bridge.

“It’s been nearly 20 years since the bridge was last painted and our work is essential to not only maintain the structure as it currently is, but to also ensure a long useful life for the future.

“The bridge has to remain operational throughout the programme of works which means that we will have in place temporary traffic lights on site to help with the management of traffic flow. These will be manually operated to help clear backlogs as they develop.

“But for those who want to avoid the bridge completely, the diversionary route will be clearly signposted to make things as straightforward as possible.

“We want to thank everyone for their continuing patience in this matter while the vital works are happening.”

It's thought a permanent replacement for the 1897 bridge could cost £100 million.
