The M40 is the quieter of the two London to Birmingham motorways, climbing through the Chilterns at Stokenchurch and joining the M42 south of Solihull. It takes the strain whenever the M1 has problems, and the J1a Denham end shares its congestion with the M25. Live incidents and closures refresh every 5 minutes.
