It happened on Wednesday morning near Kingsway Island.
Officers are appealing for witnesses to come forward following a collision on the A38 on Wednesday.
The incident occurred at 11.10am on Wednesday, 10 July, on the northbound carriageway just prior to the Kingsway island.
A blue VW Transporter van left the carriageway after colliding with a white VW Crafter van. The driver of the blue van, a 66-year-old man from Walsall, was pronounced dead at the scene. His family are aware and our thoughts are with them at this time.
The 56-year-old male driver, who is from Somercotes, of the white VW van has been arrested on suspicion of causing death by dangerous driving and has been released under investigation as enquiries continue.
Officers are keen to hear from anyone who was in the area at the time and may have witnessed the incident as well as the moments leading up to it - in particular they would like to hear from any drivers with dashcam footage.
