The B1429 is a link road in west Lincolnshire. The road was originally unclassified but got its number in the mid-1930s.
The road starts on the A17 and heads east, zigzagging a bit before following a straight route through the grounds of RAF Cranwell and the RAF College. After leaving this behind there's a brief rural section before we enter Cranwell itself. The road zigzags from College Road onto Sleaford Road then becomes straight once more as it returns to open country. The road ends shortly afterwards at a T-junction on the A15.
