Old Inns Junction

Old Inns Junction is junction 6 of the M80. It was originally built in the early 1960s as seven-eighths of a cloverleaf, the only missing movement being the sharp left turn from the SW-bound B816 to the NE-bound A80. The junction was built as part of the upgrade of the then A80, with the Cumbernauld Village Bypass to the west, and the whole road dualled. The road to the south at the time was the single carriageway A73, although this later became the A8011 and was upgraded in the late 1970s to be dual carriageway.

In the 1980s and probably as a result of the construction of Eastfield Road, which heads south west to serve Cumbernauld's northern suburbs, a roundabout was added on the north side and the north-eastern loop was removed. This finally made the junction full access, although at the expense of being free-flowing. When the A80 was upgraded to motorway as the M80, the southern loops were replaced by direct slip roads, with a signalised crossroads installed on the A8011 for right turns. This work was completed in 2011, and during the construction phase, some temporary layouts were in use to ensure traffic continued to flow throughout.

In the north east corner of the junction, next to the site of the former slip road, lies Old Inns services with a filling station, including dedicated HGV pumps, and cafes. It is marked on maps a Service Station, despite not having the normal full range of facilities.
