I got this question by my college director while I was bunking the class.

The above asked question is from General Specifications of Modern Road in chapter Specifications, Estimation of Quantities of Materials and Transport of Civil Engineering Drawing

Answer 1

Right option is (b) 3.70 m

The explanation: A single carriageway or undivided highway is a road with one, two or more lanes arranged within a single carriageway with no central reservation to separate opposing flows of traffic.

A two-lane road or two-lane highway is a single carriageway with one lane for each direction. A single-track road has a single lane with passing places for traffic in both directions. Road traffic safety is generally worse for high-speed single carriageways than for dual carriageways due to the lack of separation between traffic moving in opposing directions.
