The dead end streets grew into popularity in the 19th and 20th Centuries, with many suburbs being constructed in the developed countries such as USA, Europe, Australia and New Zealand to name a few. The Hampstead Garden Suburb Act was influential for all the Garden Cities of England including the famous Welwyn Garden City by Ebenezer Howard. The 1906 Act did not allow vehicles to pass through the cul-de-sac as they had to drive around it, and had a maximum length of 500 feet. This type of planning was thought to be ideal in suburbs with gardens as they provided more peaceful flow of traffic and low congestion rates. However, as a city planning legislation, Cul-De-Sacs were first legalised in England with the Hampstead Garden Suburb Act in 1906. It was a technique used to prevent civil wars and security against wars for passage of military vehicles during the early ancient periods.
