The new Medway Valley Crossing will help unlock the housing site near Wouldham.
Developer Trenport (Peters Village) Ltd has secured £19.5m from the Government’s Local Infrastructure Fund to start work.
BAM Nuttall will build a new stretch of road, a road bridge and a rail bridge over the River Medway to link the A228 on the west bank to the proposed Peters Village site on the east bank – which will provide up to 1,000 new homes.
The whole project is due for completion around 2022.
Trenport Director Chris Hall said: “We are delighted to be able to move forward with this ambitious and imaginative project, which will transform a once industrialised, yet important part of the Medway Valley.”
