River Lune Bridge (built as rail but now carries a road), Lune Millennium Bridge (pedestrian and cycle) and Carlisle Bridge (carrying the West Coast Main Line railway, and with a public walkway on the eastern side) which is the furthest downstream of the bridges. This part of the Lune is also the site of the old Port of Lancaster, probably a port from Roman times; the Lancaster Port Commission was established in 1750 to improve navigation on the estuary. Between 1750 and 1767, St George's Quay and New Quay were built in Lancaster and in 1779 the port facilities were extended closer
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
