River Witham Bridge Renewal

Started:Spring 2017
Completed:Spring 2017
Client:AMCO
Location:Spalding
Value:£7 million
Project Overview

The original rail bridge crossing the river Witham at Waterside North, Waterside South and Spa Road in Lincoln, was built in 1847 and has been a familiar sight to generations of Lincolnians through the years.

The mammoth task saw four spans, weighing a total of 290 tonnes and a massive 60 metres long, being removed. The centre span alone weighed in at 140 tonnes and 25 metres long. This was then replaced by 8 new decks weighing a total of 640 tonnes in just 10 days.

A gigantic 1,200 tonne capacity mobile crane with a 107 metre long jib- one of the largest in the world, was brought in to remove the structure crossing the River Witham. The crane was then used to lower a new pre-constructed bridge in to place.

The first job was to renew pre existing sections of the track and the renewal of the bridge spans within a 36 hour period

The supporting stonework pillars were then altered before work could start on bringing the new bridge decks in.

Part of the old bridge is listed so the box girders were refurbished and reinstated to maintain some of the structure's heritage.

Key Deliverables

The scope of works include;

  • Site set up

  • Installation of sheet piles for the concrete crane pads

  • Removal of a redundant gas main that spanned the existing structure

  • Demolition of Existing bridge

  • installation of new concrete pads for the new structure to sit on

  • installation of 8 new bridge decks

  • new brickwork to tie the existing pillar supports to the new structure

Reference

Just a quick note to thank you and your team for all their efforts during the past 10 days.

Despite the issues associated with realising the existing deck and the persistent rain through Tuesday and Wednesday, we handed back on time with all planned works complete.

Network Rail have been very complimentary about the scheme and specifically our ability to adapt to the developing conditions and programme.

Your assistance in making this a success is greatly appreciated.
