By-roads are often a less travelled path that can lead to hidden treasures or perhaps a shortcut to your destination. Synonyms for by-roads could include alleys, lanes, back roads, footpaths, or even shortcuts. These alternate routes can provide a more scenic journey or a faster and more efficient way to reach your destination. They may also lead to unexpected discoveries, such as a quaint cafe or a beautiful hidden garden. While they may not always be the most direct path, by-roads offer an adventure and exploration not found on the main highways. So, take a chance and veer off the beaten path to discover the charm and beauty of the lesser-known roads.
