Excerpt from Wikipedia
The Medway Tunnel is a tunnel under the River Medway linking Strood with Chatham in Kent, England. It forms part of the Medway Towns Northern Relief Road (A289). The Medway Tunnel is the first immersed tube tunnel to be built in England and only the second of this type in the UK, the other being at Conwy, North Wales.
Construction
In 1990 the Medway Tunnel Act was passed granting the Rochester Bridge Trust the power to build and own the tunnel. The work, which was carried out by an HBM Civil Engineering / Tarmac Construction joint venture, started in May 1992. The tunnel was constructed in three distinct sections. The centre part of the tunnel is the 370 metres of immersed tube, which is linked to cut and cover tunnels on both the Strood and Chatham banks of the river. The Medway Tunnel was opened by the Princess Royal in June 1996. In 1996, it won an award from the UK’s Concrete Society.
Running costs
Things that are not allowed in the Medway Tunnel. No horses, cycles, pedestrians. The detour for cycles and pedestrians is several miles long. No parking is allowed either, and there is a 50 mph speed limit (Strood side).
In 2008 negotiations were completed by the Conservative council administration which purchased the freehold of the tunnel from the trust for £1 with a £3.6m contribution on future costs. Bicycles are currently prohibited from using the tunnel which is not part of the local cycle network.
