Work is due to start in the spring on a Highways Agency scheme to develop an improved layout at Junction 12 of the M40 near the Warwickshire village of Gaydon, home of the Heritage Motor Centre (HMC). The project is scheduled for completion in summer 2016.
Warwickshire County Council is also developing a complementary scheme on the local road network, due to begin in January.
The roadworks, which will also involve upgrades to the internal roadways on the HMC site, affect the centre’s main access routes - the M40 and the B4100 - and it is anticipated there will be great pressure on these roads, particularly during rush-hour periods.
Julie Tew, managing director of the HMC, said: "It is with careful consideration to our valued customers that in order to minimise any potential disruption to client events we have released a small number or our confirmed bookings for 2015.
"The centre will be open for business as usual for meetings, events, dinners and exhibitions on Friday evenings and at weekends throughout the period of redevelopment, and we will be releasing a series of new packages to reflect this offering in the new year."
The HMC is refurbishing and expanding its museum and conference facilities during the roadworks. Its new £4m Museum Collection Centre, which will store and display more than 200 historic British cars from the reserve collections of the British Motor Industry Heritage Trust and its partner the Jaguar Daimler Heritage Trust, will be the first project to be completed, opening in Autumn 2015.
Further refurbishment works are still in the planning stage, but will include new collections and exhibitions.
The museum, Land Rover Experience, Drive Zone and weekend motoring events will continue as usual during the roadworks.
