Lane Reconfigurations (Road Diets)

Road Diets are a low-cost and highly-proven method of improving safety, mobility, and livability by reducing vehicle travel lanes and reallocating the roadway space based on community needs.



Increase economic growth

Replacing a vehicle travel lane with on-street parking, bicycle lanes, walking areas or landscaping can change a street from a place people “drive-through” to one they “drive-to.”

Improve safety for all roadway users

Road diets reduce speeding, a key factor in roadway safety. The space saved by creating a center turn lane can be used for safety improvements like new pedestrian islands or protected bicycle lanes.

Improve emergency response times

The center turn lane created by a road diet can quickly become a clear path for emergency vehicles.


A four-lane road may already operate like a three-lane road.

Left-turning cars can routinely block the inner lanes of traffic, leaving only one travel lane in each direction. Creating a center turn lane for these cars frees up space for other uses.Intersections often impact traffic flow more than the number of travel lanes does.

Fewer lanes can enable better intersection designs to help traffic flow more smoothly than before.

Road diets have been successful on streets with over 20,000 cars a day.

Before recommending a road diet for a particular location, planners and engineers evaluate traffic volume, traffic speed, road dimensions, and the surrounding community.
