|Route outline (key)|
New towns generally mean new road numbers, and this is certainly the intention with the A899 – although this road masks the importance of what was once a much more important road further along – through Uphall and Broxburn: it was the A8 in a previous life.
Dedridge - Burnside
The road begins on the A71 at Mid Calder, although this section was once the A767. The road is purposefully dualled through the middle of Livingston in the way only a New Town road could be – and it is famous for housing one of the two complete cloverleaf junctions on the entire UK road network – terminating the A705 (the junction just to the north used to be a cloverleaf as well).
The A899 clearly has a love for the unusual in junction design as it meets M8 Junction 3, a free-flowing pseudo-trumpet that halts on a roundabout almost right away at the Dechmont retail park/service area alternative. It comes to meet the A89 at another roundabout, which too used to be the A8, and then takes up that duty itself with a roundabout TOTSO at Dechmont proper. The road to the left used to be the A899 as well but that is now unclassified.
The A89 runs parallel to the south, the earlier of the A8 bypasses, whereas the A899 takes the route originally afforded to the Glasgow - Edinburgh route, straight through the West Lothian amalgamated towns of Uphall and Broxburn. The road turns to once again meet the A89 at a roundabout in the east of Broxburn, its terminus.
The road from Dechmont to Burnside through Uphall and Broxburn was numbered A8 in 1922 whilst the road to the south (the current A89) did not exist. It is marked as having Class I status, albeit unnumbered, on the 1932 Ten-Mile Map and soon became the A8 itself, with the old road becoming the A899. Although this renumbering occurred in the mid-1930s it is not known if it was part of the 1935 renumbering.
The construction of the New Town of Livingston in the 1960s required a new spine road for the settlement; this appears to have been the A899 from the beginning, despite taking the number out of zone. This gave the A899 a spur through Dechmont, which has since been declassified.
