Amity Road and Locust Grove Road Roundabout

The Ada County Highway District is designing a future roundabout for the Amity and Locust Grove intersection. The purpose of the project is to improve traffic flow and increase safety for all users.

Project Description

• Construct a roundabout at the Amity and Locust Grove intersection.
  • Amity Road legs will feature two lanes entering and exiting the roundabout.
  • Locust Grove legs will feature one lane entering and exiting the roundabout.
• Include a truck apron for larger vehicles to use if necessary.
• Add street lighting.
• Construct stormwater basins.
• Add curb, gutter and buffered multi-use pathway.
• Include crosswalks at each leg of the intersection with two-stage pedestrian crossings.
• Install Rectangular Rapid Flashing Beacons at each pedestrian crossing to alert drivers to pedestrians.
