Frontage Road - Advantages

Advantages

There are several advantages to using frontage roads. One advantage is to separate local traffic from through traffic. When frontage roads are lacking in an urban area, the highway is used as a local road, reducing speeds and increasing congestion. Another advantage occurs when the highway is closed or just obstructed. This pushes traffic off the highway. Where an urban area has frontage roads, the traffic can easily bypass the obstruction or closure on the frontage road. Where an urban area has no frontage road, traffic congests local roads searching for that elusive passage around the obstruction or closure, since there is no formal (frontage road) alternative.
