River Lune painted by J. M. W. Turner. The M6 motorway crosses the Lune near Tebay and Halton-on-Lune; in 2015 it was joined by the Heysham to M6 Link Road. The Ingleton branch line, a railway operational between 1861 and 1967, followed the Lue between Tebay and Kirkby Lonsdale, crossing the river twice on viaducts which still stand. Near the end of the non-tidal reach of the river stands the Lune Aqueduct, which carries the Lancaster Canal. The Lune is now tidal only below Skerton Weir in Lancaster. Four bridges in close proximity cross the estuary in Lancaster: Skerton Bridge (road), Greyhound
Spherical lune example, a regular hosotope {2,p,q} has digon faces, {2}, where its vertex figure is a spherical platonic solid, {p,q}. Each vertex of {p,q} defines an edge in the hosotope and adjacent pairs of those edges define lune faces. Or more specifically, the regular hosotope {2,4,3}, has 2 vertices, 8 180° arc edges in a cube, {4,3}, vertex figure between the two vertices, 12 lune faces, {2}, between pairs of adjacent edges, and 6 hosohedral cells, {2,p}. Spherical lune In spherical geometry, a spherical lune is an area on a sphere bounded by two half great circles which meet at antipodal
