On all the many OS maps that I have, motorways are blue.
On a UK Ordnance Survey map, a main 'A' road (trunk road, etc) is often shown in red.
The advantages of the British Ordnance Survey maps are:Scale of 50:000 is a general purpose map that is popular with cyclist. The 25:000 scale map (showing field boundaries and footpaths in great detail, is popular with walkers.The disadvantage is that being published in paper or laminated form, they are prone to wearing out. Opening and closing, often in rainy weather takes its toll on the map, and the most used maps would need to often be replaced. Then, being printed on paper, the map in certain areas will be quickly out of date (new housing estates, new road layouts, with new roads complicating navigating using an older map.
The two major kinds of roads on a map are typically classified as "primary roads" and "secondary roads." Primary roads, often depicted in bold lines, include highways and major thoroughfares that facilitate long-distance travel and significant traffic. Secondary roads, shown in lighter or thinner lines, connect smaller towns and rural areas, providing access to local destinations. These classifications help users navigate and understand the road network effectively.
The symbol for a main road is typically a thick, solid line on a map or road sign. This indicates that it is a major arterial road or highway used for high-volume traffic.
Dashes on a map typically represent boundaries, such as national borders, state lines, or administrative boundaries. They are used to visually indicate the separation between different regions or jurisdictions.

Since the main road was blocked, he took a secondary road.
Clarke Road Secondary School was created in 1956.
The motto of Kelly Road Secondary School is 'HART KIDS DO IT BEST!'.
The motto of Clarke Road Secondary School is 'Abeunt Studia In Mores'.
A bylane is a secondary road or lane, or a sidelane extending off a main road.
A back road is a secondary road, a little used road, or a road through rural areas sometimes used as an alternate to main roads.
In the UK, Ordnance Survey maps use red for a main road, yellow for a lane. Green may be used for principle routes, and blue for a motorway, but read the map's legend to ensure what colours are used.

There is no Pentonville Road in the American (original) version of Monopoly.
Oh, dude, enters and issues on old ordnance survey maps? It's like when you're navigating a treasure map and you come across a "here be dragons" warning. Enters are where you can enter a location, and issues are the problems you might encounter there, like a grumpy troll guarding a bridge. So, basically, it's just fancy old-timey talk for entrances and obstacles.
