Bristol Junction from Bristol Temple Meads is operated by South Western Railway, and there are scheduled coach links to most major UK cities. The M4 motorway connects the city on an east-west axis from London to West Wales, and the M5 is a north–south west axis from Birmingham to Exeter. The M49 motorway is a shortcut between the M5 in the south and the M4 Severn Crossing in the west, and the M32 is a spur from the M4 to the city centre. The Portway connects the M5 to the city centre, and was the most expensive road in Britain when
Leica M4 without a viewfinder was made as Leica MDa (similar to the Leica M1). Production of the M4 stopped briefly in 1972. Its successor, the M5 had been introduced in 1971. However, the relatively bulky and expensive M5 met with a cool reception, and sales did not live up to Leica's expectations. Production of the M4 was therefore restarted quickly until 1975. In the year 1975, a special edition was made for Leica's 50th Anniversary, and in 1977 the company launched the updated M4-2, which was based on the M4's body, but with a streamlined production process that reduced manufacturing cost.
