Curb and gutter is a type of street infrastructure that is commonly found in urban areas. It consists of a concrete curb, which separates the roadway from the sidewalk or shoulder, and a gutter, which is a channel that runs along the curb and is used to drain water away from the roadway.

Curb and gutter serves several important functions. First and foremost, it helps to prevent water from pooling on the roadway, which can cause accidents and damage to the pavement. It also helps to protect pedestrians and buildings by directing water away from the sidewalk and into the gutter. In addition, curb and gutter helps to define the edge of the roadway and provide a visual cue to drivers, which can help improve traffic flow and safety.

There are several types of curb and gutter, including standard curb and gutter, combination curb and gutter, and decorative curb and gutter. Standard curb and gutter is the most common type and is typically 6 inches high and 18 inches wide. Combination curb and gutter is similar to standard curb and gutter, but it also includes a small lip or apron on the roadway side, which helps to prevent water from splashing onto the roadway. Decorative curb and gutter is used in areas where aesthetics are important and may include unique shapes, colors, or materials.

Curb and gutter is typically made of concrete, but it can also be made of other materials such as asphalt or brick. It is usually installed by a specialized contractor, and proper installation is important to ensure its effectiveness and longevity. Proper maintenance, including regular cleaning and repair of any damage, can help extend the life of curb and gutter and keep it in good condition.

Curb and gutter are important components of any road or street infrastructure. They serve several important functions that enhance the safety, accessibility, and overall quality of the road.
