Route
Nottingham - Belper
The A609 starts at a one-way system in the centre of Nottingham known as Canning Circus, with the A610 and A6200. Heading West through Radford and Lenton (the road is the boundary), it meets the A6130 at a signalled crossroads, and the A6514 ring road at a large elongated roundabout known as the Crown Island (formerly the site of the Raleigh cycle works and now a campus of Nottingham University) before skirting Wollaton Park and Wollaton to the North, leaving Nottingham at a large signalled junction with the A6002.
Now
NSL, the A609 passes under the
M1 (after a secret exit to Trowell services) on the way to Trowell and the
A6007.
This is not a
TOTSO, though the
A6007 does multiplex with the A609 to Ilkeston, where it leaves at a roundabout with the
A6007 (itself now in a multiplex with the
A6096 as this is a high quality (though not GSJed) bypass of the high street) and
A6096; the A609 itself carries straight ahead leaving Ilkeston to the West and passing through West Hallam and Stanley Common (which seems to take an awful lot longer to do than it looks like on the map) before meeting the
A608 at a signalled T-junction. Here this is a multiplex, and we must turn right onto the
A608 to rejoin the A609 via a left turn at Smalley.
From Smalley the A609 heads West through Horsley Woodhouse and Kilburn where it turns sharp right to the North to meet the B6139, formerly the A38 and A61, at Denby Bottles. A level crossing precedes passing under the modern A38 without a junction. The A609 then enters Belper from the East (via an elongated one-way system) before ending at a roundabout on the A6.
History
