The process for how road schemes 'emerge' in the first place is not clear.
Sometimes, the DfT asks the Highways Agency to 'work up' schemes that were recommended in the multi-modal transport studies which took place between 1999 and 2003. Sometimes they are schemes that have just been hanging around since the major roadbuilding programme of the 1990s and have never gone away.
The Highways Agency usually consults on schemes early on to test opposition, but not always. The Nichols Report listed 22 schemes the Highways Agency is currently considering with a view to adding them to roads programme. Some have web pages on the Highways Agency website. If your scheme does not have a web page, contact the Highways Agency and ask it to create one.

Regional schemes
Annex B of the Highways Agency's 2006/07 business plan (610K pdf) lists the current schemes in the agency's regional and national roads programme. Many of the motorway widening schemes are now having hard shoulder running (ATM) considered as an alternative and have been removed from the programme.
