Bridgeworks get the go-ahead

Southgate Bridge, Sleaford diversion

Southgate Bridge, Sleaford is getting essential work to extend its working life.

Karen Cassar, assistant director for highways, said: “It’s great news that we can get on with carrying out the vital bridgeworks for Sleaford that will ensure the route is useable for many years to come. 

“A combination of vehicles, time and ingress of water all degrade the waterproofing layer, which can lead to damage to the bridge. Because of this, replacing the waterproofing is a preventative maintenance task undertaken every couple of decades.  

“During re-waterproofing works more in-depth structural examination of the bridge is also possible which will also enhance its service life. Whilst our specialist crews are on-site, we will also carry out protective maintenance to Southgate Bridge’s soffits and parapet fence.“ 

Dates and times

The works will begin on 29th August 2023 and last for approximately 7 weeks, subject to suitable weather.

Traffic management

Southgate will remain open to vehicles and pedestrians during working hours throughout the full duration of the works.

However, the full closure of B1517 Southgate will be required for resurfacing on two nights and this will happen towards the end of the project. Provisional planning dates are overnight on Wednesday 11 and Thursday October 12. Overnight closures will be from 20.00 to 06.00 between Southgate’s junctions with Boston Rd and Watergate.

During these two night closures it will not be possible to drive over Southgate Bridge, as the bridge will be impassable to vehicles.  

Diversion route

The diversion route will be clockwise along Carre St and Boston Road, Grantham Road westbound, then the A15 northbound to Holdingham roundabout, Lincoln Rd southeast back onto Northgate and the one-way system.

Location of works

The works will be carried out on the Southgate Bridge, B1517 Southgate, Sleaford.

Karen added: “The re-waterproofing work is being completed in two halves, to allow Southgate to remain open during the working day throughout all of the work with the exception of the two nights of work which happens at night to minimise disruption for local traffic.

“All surfacing above the existing waterproofing layer will be removed. The old waterproofing will then be stripped and the deck fully re-waterproofed. Necessary repairs to other parts of the structure will be undertaken alongside re-waterproofing.  

“Whilst we are carrying out these essential works under a scheme to keep the route open for traffic, there will be some unavoidable level of disruption. I would like to take this opportunity to thank everyone effected for their patience and understanding whilst we complete this improvement for the local area.”
