|Route outline (key)|
The B6089 is a semi-rural B-road in south Yorkshire.
Originally it started on the A630 in the centre of Rotherham and headed north along Drummond Street. This section was later bypassed and later still partly used for the A6123 Rotherham bypass. As such the current southern end of the B6089 is at a roundabout on the northern edge of town near Barbot Hall.
The B6089 heads north up the D2 Car Hill and soon reaches Greasbrough, where the road narrows again. The road crosses a stream before climbing to cross a dyke called the Roman Ridge and enter Nether Haugh, where it meets the B6091. It then bypasses Upper Haugh before crossing the B6090.
The road heads north down a narrow valley before crossing some fields and descending into Brampton. The B6097 is crossed at traffic lights on the near side of the village. On the far side, the road crosses a bridge over the A6195 Dearne Valley Parkway shortly before ending at a roundabout on the A633.
