The two-stage design and build contract is the first scheme to be commissioned under TfL’s Civils Project Framework, which supports a £4bn roads modernisation programme in the Capital, delivering the enhancement and refurbishment of tunnels, bridges and other structures.
Costain and Skanksa are the other contractors making up the three-strong panel for TfL.
The Old Street Roundabout island will be removed to form a new peninsula-style junction, reintroducing two-way traffic movements and converting the existing roundabout into an open and accessible public space.
Morgan Sindall, supported by design partners WSP, has just started detailed design, with works planned to start on site from Autumn 2018.
Paul Gott, managing director of Highways at Morgan Sindall, said: “We are delighted to be awarded the first project under TfL’s Civils Projects Framework. This scheme calls upon a wide variety of expertise, interfacing with the TfL strategic road network and London Underground’s Old St Station entrance.
“We are looking forward to starting work on this transformational scheme, and our strong track record of similar projects means we are well placed to deliver it.”
