Two cyclists were injured, one seriously, in a collision with a green, 18-tonne livestock carrier on bank holiday Monday.
The B6451 at Norwood near Otley was closed for more than five hours to allow collision investigators to examine the scene.
Police are now appealing for witnesses to the collision which happened at around 1.40pm on Monday, approximately one mile from the Sun Inn on the Otley side.
The cycles were being ridden by two Leeds men, both aged in their 20s. The livestock carrier was driven by a man in his 40s from the Silsden area.
Both the cyclists and the lorry were travelling towards the Sun Inn when the collision occurred.
One of the riders sustained serious injuries and was airlifted to Leeds General Infirmary where he remains in a stable condition.
The second cyclist sustained minor injuries and was discharged from hospital after treatment.
Police are asking for anyone who stopped at the scene of the incident to contact them if they have not already done so.
They also want to hear from anyone who was travelling along the stretch of the B6451 from Otley to the Sun Inn, who saw either the green livestock carrier or the cyclists before the collision and anyone who witnessed the incident.
Anyone who has any information is asked to contact North Yorkshire Police on 101, select option 2 and ask for Traffic Constable Steve Wright at Harrogate Roads Policing Group or e-mail firstname.lastname@example.org Quote incident number 12140084596 when passing on information about this collision.
