ROUNDABOUTS SHOULD NOT BE INSTALLED UNTIL CENTER LANE IS ADDED
Roundabouts create a continuous flow of traffic along the corridor
Left turns block traffic along the corridor (140 uncontolled connections on this corridor)
Continuous flow of traffic will cause extensive traffic delays from left turning vehicles
Center two-way turn lane removes left turners from the traffic flow
Vehicles entering the corridor turning left onto the highway have a center lane to enter before merging into traffic
Other Advantages
When school busses stop to pick up or drop off students, traffic in opposite direction is not required to stop
During gridlocked hours center lane allows emergency vehicles to pass through traffic
Center turn lane must be added (with wider shoulders) BEFORE roundabouts are installed
WHAT IS NOT REALISTIC
WHAT IS REALISTIC
Not only that, this corridor already has two-way turn lanes in a number of locations as the result of traffic mitigations for adjacent developments
The cost to accomplish this SR162 improvement redirecting current WSDOT funding
SR162, a two lane rural corridor will be trying to handle the same amount of traffic that SR410 to Bonney Lake, a four lane highway, is handling today.
This corridor cannot absorb the additional traffic (1000 more cars per peak hour) without this minimal improvement.
Wait until you see SR162 traffic volume when the new highway to Tehaleh opens.
