Consultant Mott MacDonald will lead the study into the new Thames crossings at Silvertown and Gallions Reach.
The consultant has won the contract to investigate new crossings of the Thames between Tower Bridge and the Dartford Crossing following the publication of London mayor Boris Johnson’s transport plan.
Johnson abandoned the TGB last year, saying he favoured a crossing at Silvetown – now confirmed as a tunnel (NCE 6 November 2008). Last week he resurrected the TGB as a “lower capacity” crossing renamed Gallions Reach.
He said that the crossing should initially be a ferry service that could then be upgraded to a “fixed link”.
The TGB had secured £200M in PFI credits by the Department for Transport – around half its projected cost. Engineers and planners had told NCE that work on the TGB was so well developed that construction could have begun within eight months. These plans have now been postponed until at least 2020 (NCE 13 November 2008).
Mott MacDonald’s study will examine a “new road tunnel and lifting road bridge between North Greenwich and Silvertown, a new vehicle ferry between Gallions Reach and Thamesmead, and a new lower capacity bridge at the former proposed location for the Thames Gateway Bridge,” according to a statement.
