This Urban Mobility Capital Improvement Highway Program Project makes improvements to the west approaches to the SR 285 Senator George Sellar Bridge from milepost 0.28 (the west side of George Sellar Bridge) to milepost 0.82 (Bridge Street) on SR 285/Mission Street and local streets.
In 2010, the final design alternative was endorsed by the City of Wenatchee, the Wenatchee Valley Transportation Council, and the Washington State Department of Transportation. It included widening the bridge over South Wenatchee Avenue on SR 285. That allowed an off ramp to Crescent Street. A new signal will be installed at the Crescent - Ferry intersection.
The intersection of SR 285 and Mission Street will have two left turn lanes turning from SR 285 onto southbound Mission Street. Mission Street will be restriped to allow for two southbound lanes as far as Marr Street. There will still be two right turn lanes for turning right onto Mission from SR 285.
The intersections of Marr/Mission and Wenatchee Ave/Marr will not require a signal. The intersection of Ferry and Mission will allow East and West through-movements.
This project is the last of three that address congestion and safety in South Wenatchee. For more information on all three projects click here (PDF)
Why is WSDOT
improving these intersections?
The Senator George Sellar Bridge is one of two Columbia River Crossings in the immediate Wenatchee area and serves to connect the southern ends of Wenatchee and East Wenatchee. The current local Wenatchee intersections adjacent to the west end of the bridge create choke points for traffic approaching and departing the bridge. These intersections cause gaps in the traffic flow causing substantial delay, accidents, and creates a general concern for traffic safety. Current projections show an increase in traffic volumes will lead to even more congestion if nothing was done.
The End Result
This project increased the capacity of the intersections on streets leading to the west end of the bridge, by adding lanes, limiting turning movements at intersections and bringing the streets up to current standards. These improvements will accommodate the current and expected future higher traffic flow across the George Sellar Bridge.
As required by law, in this project sidewalks and ramps are being brought up to current American's with Disabilities Act (ADA) standards.
For the benefit of cyclist and pedestrians, connections from local streets to the new pathway on the south side of the bridge are being improved.
Several new Intelligent Transportation System (ITS) elements are were installed throughout the project, including:
- An automatic congestion detection system that will alert drivers of heavy traffic or delays ahead on southbound Chelan St. traffic with a flashing beacon near the Community Center, well in advance of the bridge approaches.
- Several overhead electronic signs will transmit real-time messages to motorist passing below. One for eastbound traffic is adjacent to La Fuente's restaurant and two for westbound traffic are located on the east end of the Sellar Bridge.
- For pedestrians new flashing crossing signs are being installed at the corner of Marr and Mission and a new crossing is being added across the loop ramp from So. Wenatchee Ave. up to the bridge.
- Bottlenecks and Chokepoints: Adding additional lanes and limiting certain turns will provide for a shortened signal time, improved traffic flow and reduced delays.
- Safety: Easing congestion with added capacity and better accommodation for vehicles, bicycles and pedestrians will reduce conflict points for all users.
- System Efficiency: Synchronizing traffic signals helps maximize traffic flow.
What is the project timeline?
