Status

Complete July 2011

Construction started May 11, 2009. Work resumed in February, 2010 and was complete July 29, 2011.

This Urban Mobility Capital Improvement Project added another eastbound lane to the SR 285 Senator George Sellar Bridge to reduce congestion. It removed the sidewalks to build the 5th lane. A new bicycle and pedestrian structure was added to the southside of the bridge.

Why is WSDOT adding an additional eastbound lane?
The approaches to the George Sellar Bridge are experiencing heavy congestion, causing traffic delays.  Prior to this project the bridge had two westbound and two eastbound lanes. Now with three eastbound lanes the bridge will facilitate improvements being constructed on both the west and east sides of the bridge.

On the east end of the bridge, a two lane eastbound bypass of the Grant Rd. intersection has been built.  It reduces the number of drivers changing lanes on the bridge to take the bypass with the addition of the third eastbound lane.

On the west end of the bridge improvements began where the two eastbound lanes turning toward the bridge from Mission, must merge into one.  That's because within only a few hundred feet the loop ramp from busy So. Wenatchee Ave. feeds directly into the second eastbound lane.  This configuration creates congestion, delays and safety concerns.  The two eastbound lanes are a pinch point, creating conflicts, including collisions.

The End Result
By adding the eastbound lane to the bridge:

The east side gained a defined lane to enter the bypass. 

The west side gains a third lane matching the those feeding onto the bridge, reducing weaving, conflicts and decreasing delays.

This project removed the sidewalks from the bridge to accommodate width needed for the new lane.  A new bicycle and pedestrian structure was added to the southside of the bridge. With 4-12' lanes, 3' shoulders and sidewalks, the bridge was 54' wide. It now has 61' for 5 -11' lanes with 2' shoulders, a 2' median, plus concrete shoulder barriers.

Project Benefits

  • Reduces Driver Conflicts: Vehicles changing lanes on the bridge to take the bypass is reduced as is the collision potential.
  • Eliminating Bottlenecks and Chokepoints:  The added lane increases the flow of eastbound traffic onto the bridge from Mission Street reducing congestion and delay.
  • Increasing Highway System Efficiency:  The new lane increases the efficiency of both the eastbound on-ramp and off-ramp at each end of the bridge, improving the efficiency of the local road system as well.
