|Route outline (key)|
The A8004 is a short link road existing in its entirety as part of a sliproad for the M876 at J1, and as such it dates from the opening of the motorway. It is a bit of an anomaly, with other similar roads elsewhere generally being numbered as a spur of the main route, rather than being given their own number. Although the A8004 is two-way throughout there is considerably more traffic heading in this direction than in the reverse as the motorway's northbound offslip joins the A883 slightly further north. The equivalent southbound offslip is a spur of the B905, which meets Checkbar opposite the A8004. Some old maps suggest that this too is the A8004, but it is no longer shown as such.
The road starts at Checkbar Roundabout where the B905 meets the A883 and heads west, signposted for Glasgow and Bonnybridge. It runs adjacent to the A883 for a short distance before bearing sharply left to run alongside the M876. The road soon splits, with the left fork leading into Bonnybridge (and curiously signed as the A803), whilst the right fork passes the motorway chopsticks sign and turns into the westbound onslip of the M876.
