Routinely the M25 experiences traffic delays which can be exacerbated by trouble on the A2 snarling up road junctions in the surrounding areas. Before long local roads inevitably back up and the whole of Dartford routinely grinds to a stand still, a hostage to the traffic. Fun fact (ready irony here), the detrimental impact to local air quality is significant 'For much of a typical day in many areas close to the crossing does not meet current air quality standards.' The proposed solution is to build a Lower Thames Crossing to release pressure on Dartford/Thurrock crossing point. The road will be 23km long including a 4km twin tunnel. It will be the second longest road in the country connecting Gravesham, Kent with Turrock. The project is expected to be completed in 2027. Traffic capacity will increase across the Thames from
