Construction contract signed for $1.2bn Silvertown Tunnel project in UK


The Transport for London (TfL) has signed a contract with the RiverLinx consortium for the construction of the £1bn ($1.28bn) Silvertown road tunnel project.

The contract signing follows the selection of RiverLinx consortium as preferred bidder in May 2019 to design, build, finance, operate and maintain the Silvertown tunnel.

The RiverLinx consortium comprises Spanish infrastructure operator Cintra, Australian bank Macquarie Capital, Britain's Aberdeen Standard Investments, Dutch group BAM PPP PGGM, and South Korean contractor SK E&C.

BAM PPP PGGM is a joint venture between Royal BAM Group and Dutch pension fund administrator PGGM.

The consortium construction team of BAM Nuttall including sister company Wayss & Freytag Ingenieurbau, Ferrovial Agroman and SK E&C will now move ahead with the selection of local sub-contractors and suppliers for the Silvertown Tunnel, a twin-bore road tunnel under the Thames in east London.

RiverLinx will also commence the process of securing local stakeholder, government and environmental approval for the project.

Scheduled for opening in 2025, the project is claimed to be the first of its kind in the country to have dedicated bus lanes. It allows passengers to cross the river on one of around 37 buses an hour during peak periods.

The Silvertown Tunnel is expected to ease congestion at 122-year-old Blackwall Tunnel, improve the reliability and resilience of the road network in east London, and improve cross-river public transport connections.

To ease traffic congestion, the tunnel will connect south of the River Thames with access to the existing Blackwall Tunnel and north of the River Thames with the Tidal Basin Roundabout, in Silvertown.

The tunnel will pass under the River Thames between Silvertown and north Greenwich in London, connecting to the A1020 Silvertown Way/Lower Lea Crossing on the north side with A102 Blackwall Tunnel Approach on the south side.
Construction on the project is scheduled to commence in 2020.
