Close entrance ramp at Duvall on 183 Southbound
Eliminating this entrance ramp will allow traffic to flow through the curve and eliminate stoppage.
This entrance ramp is the sole cause of the entire 183 southbound back up. There is no merge runoff lane therefore traffic is forced to stop to allow for cars to merge in. This is turn causes a shutdown of the inside lane, which then cascades to outer lanes, which in turn stops the entire flow. This causes a shockwave that then creates a back up all the way to 620. Ever wonder why traffic flows so quickly once past this exit area? It is due to this ramp.
