Jackson has completed the PDU2 WEM Amwell Bridge Project in Hertfordshire on behalf of the Environment Agency.
Amwell Bridge was originally constructed in 1955 and provides vehicle access across the River Lea adjacent to the Amwell Nature Reserve.
The £600k project involved the construction of two reinforced concrete abutments, the removal of the existing bridge, and the installation of a new Bailey bridge with a 60 tonne capacity.
The increased capacity will enable the Environment Agency to carry out future works on the River Lea.
During construction, Jackson implemented measures to help protect local ecology and freshwater species. Over 25% of all British terrestrial and freshwater species have been recorded to inhabit in the area, including the most visible colonies of Roman Snail, Helix Pomatia.
A barrier netting was placed around the site to prevent the snails entering the operational area.
Jackson’s Sub Agent, Russell Cracknell said: “The widely anticipated bridge launch went very well and finished one day ahead of schedule.”
“This was a great achievement by all those involved particularly given the challenges we faced during installation.”
“A tidy and well executed scheme was returned to the client in July and those in the team and supply chain showed dedication to deliver throughout the project and certainly showed good works.”
