Part of the Selby bypass has been opened for traffic - decades after plans for the road were first discussed.
The new road will bypass the centre of Selby
Traffic is able to use the section from the A1041 south of Selby to where it meets the A63 west of the town.
The remaining section of the six and a quarter mile road from the A1041 to the A19 is due to open next month.
This part of the road includes a new swing bridge which has had to be built over the River Ouse.
Work started on the £44m single carriageway bypass started in July 2001.
It is designed to reduce the traffic congestion which has plagued the centre of Selby for many years.
Plans for the bypass are believed to have been first discussed in the 1930s and the campaign for a new road began to gather momentum in the 1980s.
