I have been greatly helped in this "Virtual Walk" by the National Library of Scotland who offer "This application that allows a set of historical map overlays to be viewed (against current maps)". Without this impressive research tool identifying long lost routes is unreliable or almost impossible.

I have been able to check some of the pointers used below but there are many that are imposible to check and may be inacurate!

Left towards Wolverhampton. ( See Virtual Walks-7 )

Straight ahead over the footbridge to the Cannock Extension branch.

Right towards Brownhills. ( See Virtual Walks-3).

The sign indicates what was the plan for connecting a restored Hatherton Branch Canal to the W&E via the Cannock Extension branch. Due to various problems the LHCRT now plan that a connection to the W&E will be a little farther along the route to Wolverhampton.

Access from public footpath to Lime Lane.

This was intended to be the start of the new route to the Hatherton Branch of the Staffs and Worcester, replacing the lost section that is described below. The early part of the new canal would have followed the line of the old tramway that delivered cable pulled coal tubs to the canal wharf.

The Hatherton Canal is now expected to join the W&E via the Lords Hays Branch west of Pelsall Junction. See Virtual Walks-7 Pelsall Junction to Lord Hayes Branch for more details.

Yates Brothers Boatyard - The site of the Yates canal empire that once consisted of a fleet of 400 boats. The site is now occupied by Norton Canes Boatbuilders and Denis Cooper's Canal Transport Services boat yard.

In 1982 the boatyard of M.E. Braine Boatbuilders Ltd. on this stretch of the canal was used to film the BBC Play For Today “Atlantis”. The comedy drama, staring Frank Middlemass, was transmitted on 4 January 1983. It was about the conversion of an old narrow boat into a pleasure cruiser. The show ended with a sting in the tail when the boat started its first trip but did not get very far. Peter Terson (pseudonym of Peter Patterson) had written the play while he was living on a boat here.
Does anyone remember the programme or Peter when he lived on the water here?

Access from Watling Street.

The local authority has confirmed its ownership of the footpath along the route of the disused Cannock Extension Canal from the A5 to the M6toll.

It may currently be fenced off and impassable due to its overgrown condition?

https://www.openstreetmap.org/?mlat=52.66011&mlon=-1.97147#map=17/52.66011/-1.97146

The line of the canal from the A5 Watling Street runs from top right to bottom left.

The canal would have passed under Norton Green Bridge or Nortongreen Bridge (now the west bound carriageway of the M6Toll) which took Albutts Road/Commonside over the canal.

Was there a wharf here - or does "Norton Green Wharf" refer to the point after BCN House No.213 (see below) where the canal passes north of Conduit No.4 Colliery (Norton Green Colliery)?

At various places the brickwork of the towpath edge can still be seen.

To walk along the route of the canal use the public footpath from Walsall Road beside the toll road.

NOTE – walking to Walsall Road may not be possible and the first part of the public footpath may require forcing through the encroaching brambles!
Once back on the line of the canal the going is easier.

Level with the first car the canal was crossed by a railway line running north-west (to the left) and almost immediately after the canal also veered off to the north-west

Conduit Road – named after Conduit No.3 Colliery (Jerome's) that lay at the end of the road and was served by canal basins that ran along the line of the right-hand side of the road for three quarters of its length.
