 In 1927 the Chatham Mainline was diverted to use the more substantial second railway bridge, and the original LCDR railway bridge was left unused for decades until it was eventually demolished, the piles being used for the second road bridge which opened in 1970.These days the road bridges and the services bridge are maintained by the Rochester Bridge Trust, the modern incarnation of Sir John de Cobham's Wardens and Commonalty of Rochester Bridge, which dates from 1399.The trust still owns some of the land gifted to the wardens and used the income derived from the endowments to pay for the new bridges in 1856 (now the westbound lanes of the A2) and 1970 (eastbound A2) as well as meeting all the costs of maintaining those bridges and part of Rochester Esplanade.
