The navigation system in the Saab is quite nice. It's no touch screen but the press and turn knob works ok. The big screen show you a detailed map an the upcomming turns, which are also shown on top of the dashboard, in your visual line of sight.

Nottingham & Beeston Canal, London Road, Nottingham.
Turnover Bridge, 1792-96.
By William Jessop & James Green for the Nottingham Canal Co.
Grade ll listed.
Carrying the access road to the former London Road Railway Station over the Nottingham Canal.
Probably altered 1857 when the station was built.
This type of bridge allows horses drawing boats to cross from
one towpath to another without disconnecting the towrope.
The Nottingham Canal passed into the control of the Great
Northern Railway in 1861.
The geography of the waterways in central Nottingham was, and is, complex. The city was built on the River Trent, but river navigation immediately upstream of the city had always been difficult. While the Nottingham Canal was being constructed, the Trent Navigation Company built an artificial canal - the Beeston Cut - to bypass the river from Trent Lock to Lenton. There, it met with the Nottingham Canal, which therefore became part of the river through-route. Two hundred years later, this is the only part of the Nottingham Canal to survive.

This marker is right at the confluence of the Mississippi and Ohio rivers. It is neat to see big barges navigating the river at night, using a massive spotlight to find the reflective signs as they go from marker to marker. Technology has aided navigation tremendously, of course, but these signs are still used.

I believe there's a plan to renovate these buildings. The colliery closed around 1968 and these are the most complete colliery remains in South Wales.

Navigation Colliery, Crumlin.
A wander around the buildings during a Friends of the Navigation / Cardiff University School of Architecture public event, June 2022.
". . . . the best preserved colliery complex in south Wales. . . . is of unusual architectural quality of red brick with yellow brick pilasters. The complex includes two winding engine houses, a fan house, a magnificent chimney, a pumping house, stores and workshops, a heapstead, powder store and baths."
"Known locally as the Navi, Partridge Jones & Co. Ltd. began stinking this colliery in 1907. Two shafts were completed in 1911 at a depth of 512 yards, it was well known for the very rich Blackvein seam, which in places reached a thickness of 18 feet. Employed 439 in 1945, nationalised in 1947, closed 1967"
