The first of several industry consultation days will be held in March to float a new model of public and private financing of the A303 Stonehenge tunnel and the Lower Thames Crossing project.

These projects are two of the largest in Highways England’s Road Investment Programme and are being advanced as ideal candidates for design, build, finance and maintenance contracts.

The £1.3bn A303 project includes a new twin-bore road tunnel under the Stonehenge World Heritage Site, as well as a bypass for Winterbourne Stoke and the improvement of junctions with intersecting roads.

It is currently anticipated that this project will primarily comprise a privately financed design, build, finance and maintain contract, and some associated enabling works.

The £6bn LTC project comprises two bored tunnels beneath the River Thames  between Tilbury and Gravesend with interconnecting link roads to the M25, A13, and A2.

This project could be split into a publicly financed tunnel design and build contract and a privately financed design, build, finance and maintain contract covering the associated link roads, with enabling works.

Further information is available by emailing Lesley Cole at Highways England, with firms registering an interest in attending the day by 26 January.
