The electronic sign is the only one the agency has installed at the roundabout. East-to-north drivers represent the heaviest traffic movement affected by trains crossing 32nd Street.
A contractor working for WSDOT built two roundabouts on Highway 14 this year, at 32nd Street and at Washougal River Road/15th Street.
The temporary speed limit reduction, which was in place during construction, has been lifted, and the speed limit has returned to 55 mph through the area. However, 25 mph is the recommended speed as drivers approach and travel through the roundabouts.
Additional low-cost enhancements include two newly installed electronic speed signs at both roundabouts on Highway 14 to help slow cars down by informing drivers when they are traveling faster than the recommended limit.
WSDOT faced significant opposition when it first started talking about building roundabouts on Highway 14 more than three years ago. Community concerns have waned somewhat as more residents become familiar with this type of traffic control.
Traffic engineers like roundabouts primarily because they improve safety and mobility.
Roundabouts virtually eliminate head-on and side-impact crashes, which are the most likely to result in fatalities or severe injuries. Statistics indicate that roundabouts can reduce fatal crashes by 90 percent and injury crashes by 75 percent at intersections where there were previously traffic signals or stop signs.
Roundabouts also can ease congestion since they allow for continuous traffic flow. If there is no traffic in a roundabout, a driver can proceed without stopping.
