The Mar Dyke Interchange first opened in 1982 for the new A13 Tilbury Bypass. It is built over the Mar Dyke river and the southbound slip roads have their own bridges. The interchange opened a few months before the M25 opened that December. The A13 over-bridge of the junction was built at the same time as the junction and it went unused for 16 years. This over-bridge was also notable for its lamp-post under the bridge which was unusual as most bridges tend not to have centrally placed lights underneath. In the late 1990s the A13 west finally opened and the overbridge was put into work. However the road on both sides of the bridge were D3 and it was D2 so the junction for A13 traffic has a lane drop. In the 2000s, it was signalised due to it being the main junction for Lakeside and Thurrock services. It is Junction 30 of the M25/A282.
