We Are Not Against All Roundabouts 

 

WHY ARE WE AGAINST ROUNDABOUTS – the truth is we are not

We are only against applying roundabouts in the wrong applications
 

We feel that the SR162 Sumner-to-Orting corridor is not suited for roundabouts

 

REASONS WHY

HEAVY TRAFFIC CONDITIONS 

  • SR162 currently level “F” (fail) WDSOT highway peak hour rating
  • Tehaleh highway to add 1000 more cars per peak hour
  • Gridlock bumper to bumper conditions challenge roundabout intersections
  • Roundabout protocol depends upon considerate drivers
  • Drivers commuting from King County have been in traffic for over an hour
  • Roundabout protocol adherence diminishes as patience runs lower

COMMERCIAL TRAFFIC ON SR162

  • Today’s commercial truck traffic consists of OVER 140 combination trucks PER HOUR
    • Over 1000 trucks of all types each day will negotiating roundabouts with cars (most are tractor trailer combinations)
      • That could be over 100 units per hour between 6am and 4pm using roundabout
  • Combination (tractor trailer) trucks hamper roundabout efficiency

    • Combination trucks will use two lanes in multi lane roundabouts

    • These combinations have problems entering busy roundabouts causing delays

    • Ask a combination truck driver how he/she feels about roundabouts

  • Accidents with cars and combinations will increase at roundabout intersections

TRAFFIC FLOW AT SR162/128TH ST.E. INTERSECTION

  • Major traffic flow directional changes coming to SR162
    • High percentage of SR162 traffic will be destined to the Tehaleh development
    • ​​​Much of SR162 evening traffic will be turning left at 128th St. E
  • Heavy southbound left turn flow will restrict northbound flow into roundabout
  • Traffic from Orting will find it difficult to impossible to merge pass through roundabout
    • Northbound SR162 traffic will have to cross two lanes of roundabout traffic

ACCESS & EGRESS OF CORRIDOR SERVED BY ROUNDABOUTS

  • There are over 140 access/egress points along SR162 between Sumner and Orting
  • Roundabouts meter cars causing continuous evenly spaced traffic downstream
    • Eliminating signal breaks in traffic for highway access and egress for homes and businesses
    • Entering and leaving SR162 is currently dangerous, but increased volume will make it even more risky
  • Agriculture retail business brings many customers to the valley especially seasonal volumes creating more access / egress demands on this corridor
