The following proposed improvements and design elements are identified on each plan. The purpose of each element is explained in the legend as they relate to safety improvements, vehicular speed and other roadway updates:

  • Intersection Improvements
    • Intersection improvements at existing signals to include U-turn bulbs
      • Allow drivers to make a U-turn at designated intersections
    • Designated right and left turn lanes
    • Pedestrian crossings
    • Signalized intersections
      • Improved operations
      • Protected left turn provisions
  • Raised median or barrier
    • Reduce the severity of crashes
    • Reduce the number of crashes
  • Emergency pull off areas
    • Designated areas for vehicles to safely pull over out of the roadway
    • Provides areas for traffic enforcement
  • Speed feedback signs
    • Inform driver of vehicular speed
    • Reinforce the posted speed limit
  • Advisory speed signs
    • Advise the driver that conditions ahead (curve) warrants a lower vehicular speed
  • Lit chevron signs
    • Alert drivers to roadway curves ahead
