The Dartford Cable Tunnel is a 2.4 km utility tunnel upstream of the Dartford Crossing. With a diameter of ~3 m (10 ft), it is designed to carry and allow for maintenance of 400 kV National Grid electrical cable beneath the Thames. It is accessible by foot as a crossing of the Thames, but by authorised personnel only.[1][2][3] It was built in 2003–04 at a cost of £11,000,000.[4][5]
