Project Basics

This project will be developed in two phases:

  • "Other" (OT) Phase (Phase I) - accurately assess the need, feasibility, and fundability for conceptual intersection improvements with the implementation of a roundabout. If feasible, move to Phase II.
  • “Design and R/W” Phase (Phase II) - complete detailed design and secure necessary right-of-way so that the project can ultimately be constructed.

Purpose of the project: to improve safety at the intersection.

Roundabout Specifics:

  • 12-ft. lanes, 4-ft paved shoulders on non-curbed sections
  • 12-ft. lanes, 2-ft shoulders on curbed sections
  • 18-ft. paved and striped median on the north leg
  • Variable width raised median
  • 8-ft. sidewalks (with 7-ft. boulevards) around roundabout only to connect ramps
  • LED lighting

General Roundabout Statistics:

  • 90% reduction in fatal accidents
  • 75% reduction in crashes resulting in injury
  • 40% reduction in pedestrian accidents
