[5] As the section of the A629 between Skipton and Keighley is designated as a trunk route, it is maintained by the Highways Agency as opposed to the local authorities.

Just before the Kildwick level crossing, the road takes a bypass around Eastburn and Steeton on a dual carriageway that was opened in 1989.

[14][15] Heavy goods traffic is expected to divert onto the A61 north, use the M1 motorway south and then pick up the A629 at junction 35 for Chapeltown to access the rest of the route towards Rotherham.

(although this wasn't technically the A629 but a spur connecting the A629 to the motorway network)[19] The police announced it was a pre-planned operation as they had credible information that the man was carrying a gun.

[20] As the road passes through the major conurbations of Keighley, Halifax, Huddersfield and Rotherham, it is prone to some congestion especially during the morning and evening peak periods.

The junction of the road with the A6026 and the B6112 in Saltherhebble, regularly sees queuing traffic for over a 1-mile (1.6 km) southbound that takes between 12 and 15 minutes to get through.
