伦敦的运输当局已进入在城市东侧的泰晤士河下采购计划14亿美元的公路隧道的早期阶段。如果全部进行计划，伦敦的运输将在下次春天作为一个30年的设计 - 建设金融合同，可能在2018年建设。

拟议的1公里长的Silvertown Crossing将从Greenwich Peninsula的现有Blackwall隧道的南部门口设置为东部，并在河下沿着北岸靠近皇家码头。它设计有隧道镗床驱动的Twin 11.45-M-DIA孔。

The agency is seeking comments from stakeholders through Nov. 29. The project has its critics, including those concerned about air-quality effects of increased traffic in the area. But commuters would welcome reduction of heavy traffic on the existing Blackwall crossing, which is frequently congested.

Each of the existing bores of the Blackwall tunnel now handles around 3,000 vehicles per hour for much of the working day, and congestion is set to worsen.

为了为项目提供资金，现有和计划隧道都将在一个水平上收费，以匹配使用大约30公里的Dartford向东的下一个主要交叉口的收费。

预计新的国家基础设施委员会将在伦敦运输基础设施需求的刚刚推出审查中包括Silvertown Crossing。今年10月宣布，高级别小组将建议国家基础设施优先事项的连续政府。

政府首席财务部长乔治·奥斯伯恩承诺了2020年的1520亿美元的基础设施支出，高速公路约为15％。

前交通秘书安德鲁·阿多尼斯椅委员会举办委员会，其成员包括Sir John Armitt, an engineer who was chairman of the organization that built infrastructure for London’s 2012 Olympic and Paralympic Games并坐在英格兰东南部的未来机场需要的政府委员会。

Establishing the infrastructure commission “was a bold and positive move by government, one which can enable us to reach the essential goal of a long-term infrastructure strategy,” says Armitt. “Through this new political consensus we can achieve an infrastructure revolution."
