The M8 is a motorway linking Edinburgh to Greenock via Glasgow. The Renfrew Bypass section once held the number A8(M). The Harthill bypass section, opened in November 1964 but not then extending either east to J4 or west to J5, was the second stretch of motorway in Scotland (or third if the A823(M) spur is counted separately from the M90).
Where the motorway passes close to the centre of Glasgow it forms part of the (still incomplete) Glasgow Inner Ring Road and is both the busiest and widest motorway in Scotland and the most elaborate urban motorway in Britain. As at 2012, there is a gap in the motorway to the east of Glasgow, completion of which has been proposed for many years and is likely to start in the next year or so.
Not all of the M8 was built on a new alignment. A stretch each side of junction 5, totalling about 2.6 miles, was an online upgrade a section of A8 built in the 1930s.

Main Article: Kingston Bridge
The Kingston Bridge carries the Glasgow Inner Ring Road section of M8 across the River Clyde just to the west of the city centre. The bridge has five traffic lanes in each direction, but no hard shoulders. The two outer lanes southbound are weaving lanes connecting the on and off slips either side of the river. On the north bound side of the bridge, the two outer lanes are now segregated from the main carriageway, primarily to prevent the weaving movements. These two lanes are, despite not actually connecting to the rest of the M8 in any way, still designated as part of the Motorway.
