The Coventry ring road (A4053) is a 2.25-mile (3.62 km) ring road in Coventry, England, forming a dual-carriageway loop around the city centre. The road encloses Coventry Cathedral, the shopping areas, and much of Coventry University. Except junction 1, all junctions are entirely grade-separated and closely spaced, with weaving sections between them. The road connects with three other A roads: the A4114, the A4600 and the A429. From the 1930s, Coventry City Council began replacing its medieval streets with modern roads, and Donald Gibson, the city architect, began work in 1939 on a plan that was expanded after the Coventry Blitz during the Second World War. The ring road was constructed in six stages from 1959, initially with at-grade junctions, cycle tracks and footpaths, but in the early 1960s the council amended the design to include grade separation and the weaving sections. The road was completed in 1974, with an overall cost of £14.5 million (equivalent to £191 million in 2023). (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
