A New Tunnel under the Thames

7. Include a set of drawings of your proposed tunnel, including a. a detailed cross section, b. a long section c. a map showing your suggested new road layout and d. a map indicating remedial works to minimise the impact of the extra traffic on the surrounding areas. 8. The site designated for the northern access (between Galleons Reach DLR and the river) is currently a brown field site with possible contamination, which includes an infestation of Japanese knotweed and some fly-tipping which may contain asbestos. Explain the procedures needed to bring the site into a condition suitable for construction. A new Tunnel under the Thames Introduction A tunnel is a subversive vessel, entirely covered a part from openings for entrance and exit, usually from both ends. A tunnel can be constructed for foot passage, rail, vehicle traffic, or a canal. The new Thames river crossing will allow closing of the Wool Wish Ferry. The bridge will relieve congestion for people living adjacent to Blackwall. This marks the location of Thames Gateway Road Bridge that was scrapped by the mayor in 2008, following the rejection of the plan by the Inspector at a Planning Inquiry. The tunnel, which will run from Greenwich Peninsula to the royal Docks, is expected to have a capacity of up to 2400 cars per hour in each route. While the link is very much worthy and will perhaps help reduce the severe overcrowding in the city, it will tamper with Blackwall Tunnel, making the suggestion for a Gallions Rach ferry a laughable alternative for the Thames Gateway Bridge. In addition, it raises questions with regards to the future of the current Woolwich Ferry. Supporters of environmentalists are likely to criticize the scheme of the tunnel, alleging that it would bring problems to people of London by creating more traffic, noise and more pollution. Furthermore, if the leaders in this region want to make London one of the world’s greenest capitals, their policies should be much focused (Irshad, Wagner & Mussger, 2003). Since the era when Brunel made the first Thames tunnel, which was called Rotherhithe Tunnel, the tunnel construction has undergone great breakthrough, especially between 1825 and 1842. Tunnel constructions during these times were done through a rectangular safeguard with a miner revealing the face. The dimensions of the shield were 29ft high and 33ft wide, with brick coating after the miners and an arch brick being constructed. Nonetheless, tunneling will remain a risky activity since the conditions can never be certain, regardless of the number of boreholes that are taken. Furthermore, it is not uncommon to find tunneling gaining more prominence in the next few decades. The proposed Thames Tunnel will occupy a distance of 25 kilometers from west London. It will be 67 meters below the ground and will widely follow the direction of Thames River. According to the environment agency, this tunnel will link 34 of the most contaminated sewer outflows (Munfah 2003).
