The programme includes funding to widen the A23 between Handcross and Warninglid and a new bridge on the A27 at Beddingham.
The two-lane stretch of the A23 will be increased to three lanes to match the motorway standard sections on either side. This site has been the scene of 20 deaths in the last year and at least 62 accidents resulting in injury over the past six years.
A further £19 million will go towards bridging the Beddingham level crossing which is one of the worst bottlenecks on the A27 regularly causing tailbacks of over a mile.
A wide range of agencies including the Brighton & Hove Economic Partnership and Sussex Enterprise have been calling for improvements to both roads. The A23 was due to be upgraded in the nineties but the Government withdrew money for the scheme.
Congestion is a major problem on both roads, with 63,000 vehicles a day travelling the 3.8km section of the A23 and 30,000 vehicles using the Beddingham stretch of the A27.
Construction is expected to begin in 2006 and be completed the following year.
