Budget Information

SR 542 - Everson Goshen Rd. Vicinity to SR 9 Vicinity - Complete October 2011

Overview
We built roundabouts at both the Smith Road and Nugents Corner intersections along Mount Baker Highway near Deming.

How You Benefit
Cross GlyphImproves Safety
Roundabouts significantly improve safety for drivers, reducing crashes by 40 percent, injuries by 70 percent and fatalities by 90 percent.
Car GlyphRelieves Congestion
Contrary to many peoples' perceptions, roundabouts actually move traffic through an intersection more quickly, and with less congestion on approaching roads. Roundabouts promote a continuous flow of traffic. Unlike intersections with traffic signals, drivers don’t have to wait for a green light at a roundabout to get through the intersection.

Studies by Kansas State University http://www.ksu.edu/roundabouts/ measured traffic flow at intersections before and after conversion to roundabouts. In each case, installing a roundabout led to a 20 percent reduction in delays. Additional studies by the IIHS of intersections in three states, including Washington, found that roundabouts contributed to an 89 percent reduction in delays and 56 percent reduction in vehicle stops.
Leaf Glyph Protects Environment
A Kansas State University study found that replacing four-way stops with roundabouts reduced carbon monoxide emissions by 38-45 percent and carbon dioxide emissions by 55-61 percent. Nitrogen oxides dropped 44-51 percent, and hydrocarbons fell 62-68 percent.

Other studies show that when roundabouts replace intersections with or without signals, there’s a 30 percent reduction in carbon monoxide and nitrogen oxides and a 30 percent drop in fuel consumption.
